When to Replace Your Electrical Panel in Philadelphia
A panel rarely fails without warning. Tick what you see at home and the checker tells you whether to replace your electrical panel now, plan for it, or just have it checked. Heat, buzzing and scorch marks are the urgent ones, because they mean a connection is arcing or overheating.

Residential Electrical Panel Upgrade in Philadelphia, PA
A residential electrical panel upgrade in Philadelphia usually moves a home from 60 or 100 amps to 150 or 200. The load calculation picks the size; these are the usual starting points.
Smaller homes with gas heat, gas cooking and no central air.
- Room for basic kitchen and laundry circuits
- Tight once you add central air or an EV
Mid-size homes adding central air or one large electric load.
- Space for AC plus everyday circuits
- Some headroom for one more big load
Central air plus an electric range, dryer, heat pump or EV charger.
- Top of the City EZ permit range
- Room for the loads most homes add next

Rowhome panels and working space
In a Philadelphia rowhome the panel usually sits in a tight basement, and the service often enters from the front wall. We plan the new panel spot so it keeps the working space the code requires: 30 inches wide, 36 inches deep and 6.5 feet of headroom. Service conductors are not allowed to pass through the inside of a neighboring building, which matters on shared walls.
When an outdoor disconnect is required
In Philadelphia, a service upgrade on a detached house, a twin, a duplex or a rowhome over three stories also gets an outdoor emergency disconnect. Attached rowhomes and townhomes of three stories or less are exempt, and so is a replacement in kind of an existing panel.
Breaker Panel Replacement in Philadelphia, PA
Breaker panel replacement is the right fix for these common findings on older Philadelphia panels. Each one is a reason to replace the whole panel, not patch it.
Why it mattersMany home inspectors flag these panels because of reports that their breakers may not trip during an overload.
Full panel replacement, not breaker swaps.
Why it mattersKnown for reports of breakers that loosen or overheat where they meet the bus bar.
Replace the panel and inspect the feeders.
Why it mattersAn oversized fuse screwed in by a past owner removes the protection, and there is no room for new circuits.
A breaker panel with a surge protective device.
Why it mattersNo single main breaker. Shutting the house off takes several handles, and spaces run out fast.
A main-breaker panel with room to grow.
Why it mattersOld push-button breakers, and matching replacements are hard to find.
Replace the panel rather than hunt for parts.
Why it mattersToo small for central air, an electric range or an EV charger on top of everyday loads.
A service upgrade sized by a load calculation.
Circuit Breaker Repair in Philadelphia, PA: Repair or Replace?
Circuit breaker repair in Philadelphia starts with the cause. A tripping breaker is doing its job: something on the circuit pulled too much current or leaked to ground. We find why, then fix what failed. A breaker itself is never repaired; a bad one is replaced with a breaker listed for that panel.
We repair when
The panel itself is sound.
- A loose lug or terminal that is heating up
- A double-tapped breaker with two wires under one screw
- One worn breaker in an otherwise sound panel
- A breaker too large for the wire it protects
- Nuisance trips traced to an appliance or a damaged circuit
We replace the panel when
A repair would not last.
- Burned or pitted bus bars
- A brand with a record of problems
- No listed replacement breakers available
- A full panel on an undersized service
- Water damage or corrosion inside the panel
New Electrical Panel Installation in Philadelphia, PA: What the Code Requires
New electrical panel installation for additions, gut renovations and new construction follows the 2021 residential code and the 2020 NEC, which the City's EZ standard for residential service equipment cites. In a flood hazard area the equipment sits at or above the flood elevation, and on a property listed on the Philadelphia Register of Historic Places, exterior changes such as a new meter or disconnect need Historical Commission approval.
- 1Main breaker
Sized to the load calculation. Up to 200 amps qualifies a one- or two-family home for the City EZ permit.
- 2Surge protective device
Required on all services under the code Philadelphia enforces.
- 3Outdoor emergency disconnect
For new services and upgrades on detached homes, twins, duplexes and rowhomes over three stories.

- 4Grounding and bonding
Ground rods, water and gas pipe bonding, and a supplemental electrode where required.
- 5Working space
30 inches wide, 36 inches deep and 6.5 feet of headroom in front of the panel.
- 6Circuit directory
Every breaker labeled by the room or appliance it feeds.

Commercial Electrical Panel Upgrade in Philadelphia, PA
A commercial electrical panel upgrade in Philadelphia starts with a load study of the building, not a bigger breaker. We size the service for the equipment you run now and the tenants or machines you plan to add, then prepare what the permit and PECO need: connected loads, motor details for large equipment, and a single-line diagram for three-phase service.
Multi-unit buildings get a meter and a service disconnect for each unit. We plan the shutoff with you and PECO ahead of time and prepare everything we can before the power goes off, so the business or the tenants are without power for as short a time as the work allows.
EZ permit, no plans
Replacing electrical equipment in a commercial building without new wiring, and interior wiring changes in spaces under 2,000 square feet.
Electrical permit with plans
Service upgrades and new feeders beyond the EZ limits. Three-phase requests to PECO include a single-line diagram.
Building permit first
Renovations need a building permit before the electrical permit issues. Healthcare, hazardous locations, changes of occupancy and fire pumps always need plans.
From First Photo to Shutoff Day
Whether you replace an electrical panel in kind or upgrade the whole service, you know the shutoff date in advance and the power-off window is planned.

Electrical Panel FAQs for Philadelphia
62 questions homeowners and building owners ask us most. Filter by topic, or search if you already know what you need.
How much does electric panel replacement cost in Philadelphia?
It depends on whether we replace the panel in kind or raise the amperage, the condition of the meter socket, service cable and grounding, and whether the code calls for an outdoor disconnect. You get a written price after we see the panel and meter.
Is 100 amps enough for my house?
Sometimes. A smaller home with gas heat and gas cooking may do fine on 100 amps. Central air, electric heat, an electric range or an EV charger usually push you toward 200. A load calculation settles it.
Are Federal Pacific and Zinsco panels dangerous?
Many home inspectors flag both brands because of reports that their breakers may not trip during an overload or may overheat at the bus. We recommend replacing the panel rather than swapping breakers.
Will I lose power during a panel replacement?
Yes, for the shutoff part of the job. When PECO needs to disconnect and reconnect the service, we schedule it with them and tell you the date ahead of time.
What is the difference between a panel replacement and a service upgrade?
A replacement swaps the panel at the same amperage. A service upgrade raises the amperage, which usually means new service cable, a new meter socket and work with PECO.
Does a new panel need surge protection?
Yes. In Philadelphia every service needs a surge protective device under the code the City enforces. It is part of the job, not an add-on.
Will a new panel help when I sell my house?
Buyers' home inspectors flag fuse boxes, Federal Pacific and Zinsco panels, and double taps. A permitted, inspected replacement answers those items before they come up.
Why does my breaker keep tripping?
Too much load on the circuit, a short circuit, a ground fault, or a worn breaker. Frequent trips on one circuit point to that circuit. Trips all over the house point to the service.
What does buzzing from the panel mean?
Usually a loose connection or a failing breaker that is arcing. It gets worse, not better, so have it checked soon.
How old is too old for an electrical panel?
There is no fixed age. Brand, condition, capacity and room for circuits matter more. An original panel in an older home is worth a check, especially before you add big loads.
Can I add breakers to my old panel instead?
Only if the panel has room, the service has capacity and the brand is sound. Tandem breakers in an overloaded panel often cause the trips you are trying to stop.
What is a load calculation?
A method in NEC Article 220 that adds up your square footage, appliances, heating and cooling to find the service size your home needs.
I'm switching to a heat pump. Do I need a panel upgrade?
Maybe. A heat pump adds a large load, especially with electric backup heat. The load calculation tells us whether your current service can carry it.
Will a subpanel fix my problem?
A subpanel adds breaker spaces, not capacity. If your service is too small, a subpanel only spreads the same amps around.
Which panels should be replaced instead of repaired?
Federal Pacific Stab-Lok, Zinsco, split-bus panels, Pushmatic panels, fuse boxes, and any panel with burned bus bars or water damage.
Can you replace the panel without changing the meter?
Often, for a replacement in kind. If the amperage goes up or the meter socket is worn, the socket is replaced too.
How long does a panel replacement take?
Most single-family replacements fit in one shutoff day. Service upgrades with PECO work, meter changes or grounding repairs can take longer, and your quote gives the schedule.
Do you check the grounding when you replace a panel?
Yes. We check the ground rods, the water and gas pipe bonding and the grounding conductor, and bring them up to code with the new panel.
Can a circuit breaker go bad?
Yes. Breakers wear and can fail to trip when they should, which is more dangerous than tripping too often. A bad breaker is replaced.
What is a double-tapped breaker?
Two wires under a screw made for one. The connection can loosen and overheat. We fix it with a pigtail or a new circuit.
Why does my GFCI or AFCI breaker keep tripping?
It is sensing a leak or an arc. The cause is often an appliance, a damaged cord or a wiring fault on the circuit. We trace it before replacing anything.
Who inspects panel work in Philadelphia?
A licensed electrical inspection agency, hired for the permit, inspects the work. The City issues a Certificate of Approval once the inspections pass. We schedule it and meet the inspector.
Can a homeowner pull the permit?
A property owner or an authorized agent can apply, but the City requires a licensed electrical contractor to do all electrical work. We file it as your contractor.
My house is on the historic register. Can I still upgrade?
Yes. Exterior changes such as a new meter or disconnect on a property listed on the Philadelphia Register of Historic Places need Historical Commission approval first.
Which code does Philadelphia use for panel work?
The City's EZ standard for residential service equipment cites the 2021 International Residential Code and the 2020 National Electrical Code.
What does a commercial panel upgrade involve?
A load study, the right permit path, PECO paperwork with connected loads and a single-line diagram for three-phase service, and a planned shutoff.
Do I need a building permit too?
For renovations, yes. In Philadelphia the electrical permit is not issued until the building permit is.
Do you upgrade multi-unit buildings?
Yes, including meter banks with a meter and service disconnect for each unit.
Which commercial jobs always need plans?
Healthcare facilities, hazardous locations, changes of occupancy in non-residential buildings, and fire pumps.
Do I need to be home on shutoff day?
Someone needs to let us in and give access to the panel and meter. We walk you through the new labels at the end.
Can you fix the panel items on my home inspection report?
Yes. Send us the report. We fix each panel item and give you a written list for your buyer or agent.
How do I know if I need to replace my electrical panel?
Breakers that trip often, a hot cover, buzzing, scorch marks, a fuse box, a Federal Pacific or Zinsco panel, or no room for new circuits. Planning a big new load like an EV charger is another reason.
Do I need a permit to replace an electrical panel in Philadelphia?
Yes. Panel and service work needs an electrical permit through L&I. Service equipment up to 200 amps at a one- or two-family home can qualify for an EZ permit without plans. A licensed electrical contractor must do the work.
Can a circuit breaker be repaired?
The breaker itself is replaced, not repaired. Circuit breaker repair means finding why it trips or fails, fixing loose connections or double taps, and installing a new breaker listed for your panel.
Do you upgrade commercial electrical panels?
Yes. We upgrade panels and services for storefronts, offices, restaurants and multi-unit buildings, starting with a load study and the permit path your project needs.
Why does my quote include a meter socket or service cable?
If they are corroded, cracked or too small for the new service, replacing them on the same shutoff day avoids a second outage and a second permit.
Will I need an outdoor emergency disconnect?
For a new service or an upgrade on a detached home, twin, duplex or rowhome over three stories, yes. Attached rowhomes and townhomes of three stories or less are exempt, and so is a replacement in kind.
Do you give a written quote?
Yes. You get the full scope and price in writing before any work starts.
Is it normal for my panel to feel hot?
No. A hot cover, a burning smell or scorch marks mean a connection is overheating. Turn off big loads and call an electrician right away.
My lights dim when the AC starts. Is it my panel?
Some dimming at startup is normal. Heavy or growing dimming can mean loose connections at the panel, meter or service. We test the connections, and if the problem is on the utility side we tell you to call PECO.
Should I replace my fuse box?
We recommend it. Fuse boxes have no room for modern circuits, and an oversized fuse put in by a past owner removes the protection the fuse is supposed to give.
Should I upgrade to 200 amps?
If a load calculation shows you need more than 100 or 150 amps, 200 is the common choice. It fits central air plus an electric range, dryer, heat pump or EV charger in most homes.
Can I get more than 200 amps at my house?
It is possible, but in Philadelphia residential service equipment over 200 amps falls outside the EZ permit and needs plans. PECO also needs your load details.
Where can the new panel go in a rowhome?
Anywhere that keeps 30 inches of width, 36 inches of depth and 6.5 feet of headroom clear in front of it, and not in a bathroom or clothes closet. Basements usually work.
Do you install surge protection with the new panel?
Yes. Philadelphia requires a surge protective device on every service, so it goes in with the new panel.
What is a split-bus panel?
An older design with no single main breaker. Shutting off the house takes several handles, and the panel usually has little room for new circuits.
Can you move my panel to another spot?
Yes, within the code rules for location and working space. Moving the meter also needs PECO, so check with them before equipment is bought.
Do you label the new breakers?
Yes. Every breaker gets a label for the room or appliance it feeds, so you can find the right one fast.
Why does my breaker trip right away and not reset?
That points to a short circuit or ground fault on the circuit. Do not keep resetting it. Unplug what is on the circuit and call us.
Can I use any brand of breaker in my panel?
No. Use breakers listed for your panel. The panel label names the breaker types it accepts.
What is the difference between AFCI and GFCI breakers?
An AFCI breaker trips on arcing in the wiring, a fire risk. A GFCI breaker trips when current leaks to ground, a shock risk. Some breakers do both.
My breaker is hot to the touch. Is that dangerous?
A breaker running hot points to a loose connection or an overloaded circuit. Reduce the load and have it checked soon.
What is the Philadelphia EZ permit for service equipment?
An L&I standard that lets service work at one- and two-family homes, with equipment rated 200 amps or less, be permitted without plans when it meets the standard.
Does PECO need to approve a service upgrade?
Yes. Upgrades, relocations and load changes go to PECO on its service application, and PECO does not start its part until it has the required information.
Can my service wires run through my neighbor's house?
No. Service conductors cannot pass through the inside of another building, which shapes the route on rowhome blocks.
Who issues permits on the Main Line?
Lower Merion, Upper Merion, Radnor, Tredyffrin and Easttown each issue their own electrical permits. Wayne and Berwyn cross township lines, so we file with the one your address sits in.
Do commercial panel jobs need plans in Philadelphia?
Service upgrades do. The EZ permit covers replacing electrical equipment without new wiring, and interior wiring changes in spaces under 2,000 square feet.
Can you add three-phase service?
We plan it with PECO. Their application asks for a site plan and a single-line diagram for three-phase service, and service availability is checked before equipment is bought.
How do you keep downtime short for a business?
We plan the shutoff with you and PECO ahead of time and prepare everything we can before the power goes off.
What photos should I send for a quote?
The panel label, the open panel door with the cover on, the main breaker or fuses, and the meter outside where the wires enter.
Which areas do you serve for panel upgrades?
Philadelphia, Lower Merion, Upper Merion, Wayne and Berwyn, plus nearby Main Line towns.
