Moving from an outdated 60 or 100-amp panel to modern 200-amp service. Learn what the job involves, what it typically costs, and how to be connected with an independent electrician.
Your electrical panel is the heart of your home's electrical system — and much of Rhode Island's housing stock is running on panels that were installed decades ago. Warwick Electric Service is a referral service that connects homeowners in Warwick and the surrounding communities with independent electricians who upgrade and replace panels. We do not do the electrical work ourselves.
Call (401) 249-4614 to Be Connected| Project | Typical Range |
|---|---|
| Panel replacement, same amperage (100A to 100A) | $1,500 – $2,500 |
| Upgrade from 100A to 200A service | $2,500 – $4,000 |
| Fuse box to breaker panel conversion | $2,000 – $4,000 |
| Add a subpanel (garage, addition, workshop) | $800 – $1,800 |
Ranges are general planning estimates, not quotes. Price depends on panel location, service entrance condition, whether the meter socket needs replacement, and utility coordination. Ask the electrician for a written price after they have seen the panel, and confirm whether the assessment is free.
A standby generator is another reason to look at the panel. A whole-house unit ties into your electrical system through a transfer switch, so the panel's capacity and layout affect the job. Our guide to whole-house generator costs in Rhode Island covers what drives the price.
Panel work in Rhode Island requires an electrical permit and municipal inspection, and a service upgrade also requires coordination with Rhode Island Energy to disconnect and reconnect power. Ask the electrician you hire who will pull the permit, schedule the inspection, and arrange the utility appointment. Many panel replacements are completed in a single day, though timing varies by home and utility scheduling.
Certain panel brands — most notably Federal Pacific Electric (FPE) with Stab-Lok breakers and Zinsco panels — have documented histories of breakers failing to trip during overloads. Many home inspectors flag them automatically and some insurance carriers charge higher premiums or decline coverage until they're replaced. If your home has one, replacement isn't just a capacity question, it's a safety one. An electrician can identify what you have and give you a straight answer during an assessment.
Yes. Panel replacement requires an electrical permit and a municipal inspection, and upgrading your service capacity also requires coordination with Rhode Island Energy to disconnect and reconnect power at the meter. Ask the electrician you hire who will handle that scheduling.
Often four to eight hours, though it varies by home and utility scheduling. Many panel replacements start in the morning and have power restored by evening of the same day. Ask the electrician for the expected window before work begins so you can plan around it.
No law forces you to. But both brands have documented histories of breakers failing to trip during overloads, home inspectors flag them automatically at sale, and a growing number of insurance carriers surcharge or decline coverage until they're replaced. It's a safety decision first and an insurance decision second.
Sometimes. If your existing service has spare capacity but the panel is simply out of breaker slots, a subpanel is the cheaper fix. If the problem is total capacity — you're adding an EV charger, heat pump, or central air to a 100-amp service — a subpanel doesn't solve anything, and the service itself needs the upgrade. A load calculation tells you which situation you're in.
It removes one of the most common home-inspection flags. Fuse boxes, 60-amp services, and Federal Pacific or Zinsco panels routinely show up in inspection reports and become negotiating points or insurance obstacles for buyers. A modern 200-amp panel takes that issue off the table.
