Electrical Panel Upgrades, Wiring & Rewiring

Panel upgrades, circuit installation, and whole-house rewiring. Licensed electricians. SE MA and Rhode Island.

Electrical Work You Can Trust

Still on a 100-amp panel from the 1970s? Adding a heat pump, EV charger, or hot tub? Your panel probably cannot handle the load. We upgrade to 200-amp service and add the circuits you need.

For older homes in Fall River, Swansea, New Bedford, and across RI, we do full and partial rewiring. Knob-and-tube, aluminum wiring, and outdated fuse boxes are fire hazards and insurance risks. We replace with modern copper and breaker panels to current code.

Our electricians are on staff, not subcontracted. That matters because electrical connects to HVAC, plumbing, and appliance projects. Installing a mini split? Our own electricians handle the panel work. One company, one invoice. Switching oil to gas? We wire the new thermostat ourselves.

Why Homeowners Choose Triangle for Electrical Work

In-House Electricians

Most HVAC installers sub out the panel work. That means two companies, two schedules, two invoices. Our own electricians handle the panel work. One company, one invoice.

Mass Save Participating Contractor

We know which systems qualify, what documentation the program requires, and where homeowners usually lose money by picking the wrong equipment tier. We confirm your eligibility before you spend a dollar.

55 Years. Not a Startup.

Rebate money brought a lot of new companies into this market. Triangle has been at 425 Pleasant Street in Fall River since 1970. When your compressor needs warranty service in 2030, we will still be here.

Getting a mini split and notice the water heater looks rough? Want a generator quote while we are there? Heating, cooling, plumbing, electrical, refrigeration. One call, one truck, one bill.

How much does a 200-amp panel upgrade cost?

$3,000 to $4,500 depending on condition and meter base. Quoted before work starts.

Do I need a panel upgrade for a heat pump or EV charger?

Usually yes. Heat pumps need 30-60 amps, EV chargers need 40-50 amps. If your panel is at capacity, upgrading is the safe solution.

How do I know if my house needs rewiring?

Frequent breaker trips, flickering lights, warm outlets, burning smell, visible knob-and-tube in the attic. Pre-1970 homes in Fall River, New Bedford, and Providence often need it.

Do you handle outdoor lighting?

Yes. Exterior, landscape, and outdoor outlet installations. Call (508) 501-7424 for an estimate.

Do you pull permits for electrical work?

Every job that requires one, which is most of them. Panel upgrades, new circuits, and rewiring all need permits and inspection in Massachusetts and Rhode Island. We file, meet the inspector, and close it out. Unpermitted electrical work can void your homeowners insurance, so do not skip this.

How long does a panel upgrade take?

Most 200-amp upgrades are done in one day. Power is off for four to six hours while we swap the panel and the utility reconnects. Utility coordination adds lead time in Fall River and Somerset, so call (508) 501-7424 a few weeks before you need it done.

Whether you need an emergency repair, a new installation, or a second opinion, Triangle is here to help. One call handles it all.
