Electrical panel upgrades

When to consider it

Many houses were wired long before central air, home offices, heat pumps and EV chargers. A licensed electrician should look at the panel if:

• Breakers trip often or the panel is full
• The house still has a fuse box
• You plan a whole-home generator, EV charger or addition
• The panel feels warm, buzzes or smells of burning (call an electrician right away)

Panels and generators

A whole-house transfer switch must match your service. If your house has 100-amp service and you want to add a generator plus air conditioning or an EV charger, an upgrade to 200 amps may come first. Doing the panel and the transfer switch in one project usually saves labor and permit steps. See automatic transfer switches.

What happens on the day

The electrician coordinates with Con Edison to shut off and later restore the service. They remove the old panel, install the new one, reconnect and label circuits, and often replace the meter socket or service cable. The house is usually without power for part of the day. A permit and inspection are required, and the electrician handles both.

Fuse boxes

Some older Westchester houses still have fuse boxes. Fixr puts replacing a fuse box with a modern breaker panel at about $1,500 to $4,500, depending on the amperage. A transfer switch is generally added to a modern breaker panel, so a fuse box is usually replaced first.

Safety

Panel work is high-voltage work and must be done by a licensed electrician. If you see scorch marks, smell burning or hear buzzing from the panel, keep clear and call an electrician, or 911 if there is smoke or fire.

Planning ahead

If you expect to add a generator, EV charger, heat pump or addition in the next few years, tell the electrician now. Sizing the new panel and service with those loads in mind can avoid a second upgrade later. Ask for a written list of the circuits the new panel will hold, how many spaces will be left open, and whether the meter socket and service cable are being replaced or reused. Keep the permit sign-off with your house records.
