Electrical Panel Upgrades

Your electrical panel decides how much power the rest of the house can safely use. When it is old, undersized or simply full, everything downstream is working around the problem — breakers that trip when the microwave and the air conditioning run together, lights that dip when the well pump starts, an EV charger you have been told you cannot add. Castro Electric replaces and upgrades panels across Richmond, Chesterfield and the surrounding counties: we size the new service, pull the permit, coordinate the meter with Dominion Energy, and hand back a labelled panel with room to grow.

Signs it is the panel, not the circuit

• The same breaker trips again and again, or the breaker feels warm to the touch
• A fuse box, or a 60-amp or 100-amp service in a house that has since gained central air, a heat pump or a hot tub
• No spare spaces left — or two circuits doubled onto one breaker to make room
• Scorch marks, a smell of hot plastic, rust or water staining inside the cover
• Lights across the house dim noticeably when a large appliance starts up
• An insurer, home inspector or buyer’s agent has flagged the panel during a sale

Some of these turn out to be one bad circuit and a two-hour repair. Some of them are the panel itself. We would far rather come out and tell you it is the cheaper of the two.

Federal Pacific, Zinsco and 60-amp fuse boxes

Richmond-area housing stock spans more than a century, and the panel tells you roughly when the house was wired. The Fan, Church Hill and Northside still hold homes on their original 60-amp services, sometimes with a run of knob-and-tube left in a wall. Much of Chesterfield and Midlothian — Brandermill, Woodlake and the neighbourhoods built around them — went up while Federal Pacific and Zinsco panels were the standard fit.

Those two brands matter more than the rest. Federal Pacific Stab-Lok panels were installed from the 1950s through the 1980s, and independent testing has put their breaker failure rates somewhere between 25% and 65%. A breaker that does not trip when it should leaves the wire behind it to carry more current than it was ever sized for. Zinsco panels have much the same reputation. Most insurers now decline to cover a home that still has one, or price it at a penalty — which is how a great many people find out they have one at all.

If you can read the brand name on the panel door, send us a photo. We can usually tell you what you are looking at before anything is scheduled.

What the work involves

A straightforward panel replacement is a one-day job. Here is what the day actually looks like.

1. Load calculation. We size the new service to the house you have now, not the one it was in 1972 — heating and cooling, range, dryer, water heater, hot tub, EV charger and anything else you have planned.
2. Permit. We pull it. You file nothing.
3. Power off and meter pull. Dominion Energy disconnects at the meter. Plan to be without power for most of the working day.
4. Out with the old. The existing panel comes off the wall, along with the meter base if it is being replaced.
5. New panel and service. New panel and breakers, new grounding electrode conductor and bonding, and arc-fault and ground-fault protection where the code now calls for it.
6. Every circuit relabelled. Properly, by what it actually feeds — not “bedroom?” in pencil.
7. Inspection. The county or city inspects the work. Once it passes, Dominion reconnects and we test the house before we leave.

If the meter base, weatherhead or service entrance cable also needs replacing, that happens the same day — it is the same outage and the same inspection, and splitting it means paying for both twice. Worth knowing: Dominion’s crews restore power only as far as your point of connection. Everything from the weatherhead down to the meter base is an electrician’s work, not the utility’s.

What a panel upgrade costs around Richmond

Panel work does not have one price, and anyone who quotes you a firm number over the phone without seeing the panel is guessing. These are the things that actually move it:

• Whether you are replacing the panel alone, or the panel plus the meter base and service entrance cable
• A 100-amp to 200-amp service upgrade versus a like-for-like replacement
• Where the panel sits and how easily it can be reached — a finished basement wall costs more than a garage
• Aluminium branch wiring, damaged conductors, or circuits that have to be brought up to current code
• Permit and inspection fees, which vary by jurisdiction
• Whether a sub-panel is going in for a garage, workshop or addition

We look at the panel, run the calculation and give you the number in writing before any work starts. The figure on the quote is the figure on the invoice — unless we find something behind the wall, in which case you hear about it before we carry on, not afterwards. Estimates are free, and we would rather tell you the job is smaller than you feared than talk you into a service upgrade you do not need.

Permits and inspections

Panel and service work is permitted work everywhere in this region, and an unpermitted panel is a problem you inherit at resale. We handle the paperwork.

• Chesterfield County permits go through the county’s Enterprise Land Management portal, with inspections booked online or on the automated line at 804-751-4444. Inspections can be scheduled up to five business days ahead, which is why we book yours the day the permit is issued rather than the day we start.
• City of Richmond work is permitted and inspected through the Department of Planning and Development Review.
• Henrico, Hanover and the surrounding counties each run their own process. We work in all of them regularly and know what each inspector expects to see.

Everything is installed to the 2020 National Electrical Code, which Virginia adopted statewide on 18 January 2024.

Do you actually need 200 amps?

Not always, and we will tell you if you do not. A 100-amp service is still perfectly adequate for plenty of homes. But the list of things that push a house past it keeps getting longer: a heat pump, an induction range, a heat-pump water heater, a hot tub, a conditioned garage or workshop — and above all a Level 2 EV charger, which can pull as much as the rest of the house put together.

The honest answer comes out of the load calculation, not a rule of thumb. If an EV charger, a hot tub or a garage conversion is anywhere in the next few years, say so when we quote. Sizing the service once is considerably cheaper than sizing it twice.
