Power from the electrical company's line flows through a home's outside meter and into the electrical service panel, which controls the flow of electricity into the house. Total electrical usage cannot exceed the panel's capacity, which can be 100, 150, 200 or 400 amps. Homes may also have sub-panels that are located elsewhere, which are smaller versions of the main panel and wired through it.

Typical costs:

  • Typically it costs $800-$1,200 to have a qualified electrician upgrade an existing panel to 100 amps, or $1,500-$2,500 if a new panel is needed.
  • Expect to pay $1,300-$3,000 to upgrade to 200 amps, or $2,000-$4,000 to go to 400 amps.
  • Installing a new sub-panel runs $500-$1,000.

What should be included:
  • Electrical panels in an older home might have a lower capacity, but 100 amps is the current minimum required, while 150 amps is common. Many new homes are being built at 400 amps, which usually is achieved by using a 400-amp meter and two 200-amp panels.
  •[1] describes and illustrates a typical main electrical panel, while[2] provides a detailed glossary of electrical terms, which helps in understanding exactly what is included in a quote or required in a specific situation.
  • This is not a do-it-yourself project; major wiring changes should be done by a licensed electrical contractor. Check with your local planning department for any local restrictions or requirements; generally a permit is needed. Permit costs vary widely nationwide.
  • If needed, the upgrading process can include repairing old wiring, adding a copper grounding pole, and removing and replacing the old panel.
Shopping for upgrading an electrical panel:
  • Get estimates from several companies or contractors. Check references, search for complaints with the Better Business Bureau[3] and make sure the electrical contractor is properly bonded and insured, as well as licensed in your state[4] .
  • Referrals to electrical contractors are available from the National Electrical Contractors Association[5] .

The full service also included a new door bell installation, and two dead outlets being repaired. The electrician at the outside box did great work. The company sent two less experienced persons to do the inside outlet repairs and door bell work. Those two were not good at all. They did not test theirs repairs and had to be called back into the house from the truck. I did get a lifetime service contract on the whole package- but I think the work was overpriced by about $1,000.

Panel Upgrades
Amount: $2,000.00
Posted by: DSiggy60 in Union, ME.Posted: August 2nd, 2013 03:08AM
Just a note on panel upgrades. For a majority of the states electrical code panels (2011 National Electrical Code), when upgrading a panel, a majority of breakers must be replaced with the Arc-Fault type. this may increase the past cost of the job by as much as $50 a breaker.

John(the owner) did a very neat and clean 200 amp service upgrade for me at my home in richboro, pa. My existing panel was way to small and my outside service cable was cracked and dry rotted. I am a realtor and I have recommended and used him on numerous service upgrades and panel changes. The best part is that he always answers the phone personally and does the work himself.

Posted by: KarenSue in Oakdale, MN.Posted: February 7th, 2013 05:02AM
Amps: 200Electrician: Kevin~3hrs work.wont use again.
Electrician to put in new meter socket $980.00. Includes (200A meter socket hardware).

Excel energy changed per foot to dig a trench to bury my overhead lines, then there is a $350.00 minimum fee to come out and connect (all happens on same day).

They buried my power lines 72ft distance from pole to house. Total Excel energy cost $808.00

The 200A breaker box was $125, and an extra 100A breaker for the existing panel $50.(didn't let electrician change old 100A fuse box, he was told to send a jumper from 200A to 100A fuse box only.)

Not included in the cost shown above ::
I changed the existing 100A fuse box to a 100A breaker box. Took me 5 hours. Glad I didn't let the electrician do it at apparently ($290 per hour). Cost of panel and breakers $200.00. Cost of 5 hours of my time.... priceless.

Electrical Service Upgrade-Main Service Line & Panel
Amount: $2,350.00
Posted by: Al Nice in Piscataway, NJ.Posted: August 12th, 2012 02:08PM
Amps: 200Electrician: 24/7 Electric, LLC
After reviewing electricians on, I decided to go with a local electrician here in Piscataway. He also had awesome reviews from customers so I felt comfortable in hiring him. We recently had our kitchen redone and noticed whenever we used the microwave with other applianced plugged in at the same time, the power would cut out. I hired Tony from 24/7 Electric and he made few suggestions to us. We decided it was necessary to upgrade our panel box and main service line outside due to old wiring, aluminum acid build up, old circuit breakers, etc. Added a circuit breaker for the microwave. 24/7 Electric went straight to work without any breaks. They never had any problems while working. They were very courtesy and professional. I would hire these guys again for my next project.

After getting several estimates on this project we were referred to this contractor. His pricing was competitive and he included add-ons in the basement to bring the home up to current code. The others never mentioned these requirements. The owner was on scene. All their material was laid out in an organized manner. A big relief for me to see based on past experiences. The work was completed in a timely manner and the quality was beyond our expectations. If you are in need of a professional electrician in central New Jersey, Call Citywide

Just bought a house built in 1960's that came with an old Zinsco 100 amp panel. Upgraded it to a 200 amp panel. We expected to pay about $2000 and spent just a little over that. Electrician handled permit and coordinating with PG & E, and the county building inspector for the "rough in" (first permit check). Felt it was fair price and money well spent. (This was done in 2012- the date thingy didn't let me change it to 2012.)

Amps: 150Electrician: Milestone electric
Milestone is going to come in and replace and move my breaker box that is original to my house built in 1970's. The one I have is no longer safe because of the brand, and time it was installed. I thought the price was high but they added in so many other things they are going to do at no extra charge. They also guarantee their work for the life of the electric panel.
I did not want just anyone doing this job. after all, it's my house we are talking about. so I felt Milestone was the best company for the job. they are experienced, and backed by the BBB. A great company.
By the way, my old panel was a Federal Pacafic Electric Panel.

House built in 1978. Breaker faulty so entire box has to be replaced. Amazing how "code" requires them to replace all breakers, but if that is done then they have to replace the aluminum pole, and install new ground and and and.... so a $2000 cost for box replacement almost triples, all because the breaker isn't made anymore. I am getting other quotes.

If you get people like Mister Sparky to do your work you are paying about 3 times to much. If you get a local electrician to do it your paying a few hundred extra. Get a guy who works for a company and does it on the side too. The total cost for a new panel and breakers is about 300 bucks (depending on how many breakers and what not). I'll gladly pay someone 400 in labor to wire in my panel while its hot and have it done in a few hours.

I feel like the price was reasonable, but I am not sure.

Regarding not waiting for a line crew to show up and disconnect the service providers power lines. Here in California getting caught by the serivce provider disconnecting their lines will get the contractor in alot! of trouble. All Electricians are supposed to obtain approval from the power provider/pull a permit/have it inspected by the municipality and then the inspector issues a "meter release" to the power provider and then they line men come back out and install their "permanent splices" to the overhead wires at the weather head. These proprietary splices are how the company can tell if a "bootleg" job was done. If a private electrician grounds those wires it could pull down many house, or if they were to drop the wires on someones house or accross the street their could be huge liability issues, and it could cost the homeowner money, and the electrician his license. Just the facts.
