Electrical Panel Upgrade in Colorado

Your panel is the heart of the electrical system, and most of the trouble people blame on old wiring actually starts there. If your Colorado home still runs on 60 or 100 amp service, a fuse box, or a brand with a known failure history, an upgrade buys you capacity for the way houses are actually used now, with EV chargers, heat pumps, induction ranges and home offices all drawing at once.

Frequently asked questions

How do I know my Colorado home needs a panel upgrade?

Common signs are a fuse box instead of breakers, a panel with no free slots, breakers that trip when two appliances run together, lights that dim when the dryer or AC starts, rust or scorch marks inside the cover, or a plan to add an EV charger, hot tub or air conditioning. If you are unsure, we will read the label and load and tell you honestly whether you need it.

How long does a panel upgrade take?

Most residential 200 amp upgrades in Colorado are done in a single day. Power is off for a portion of that while the service is disconnected and reconnected. Larger homes, meter base replacements and utility coordination can push it to two days.

Do I need a permit for a panel upgrade in Colorado?

Yes. Service changes are permitted and inspected work everywhere in Colorado. We pull the permit, coordinate the utility disconnect and reconnect, and meet the inspector so the upgrade is properly closed out on your property record.

Is 200 amp service enough for a modern home?

For the large majority of Colorado homes, yes. 200 amps comfortably covers electric heat or a heat pump, an EV charger, a range, a dryer and normal household loads. Very large homes, shops with welders, or households running two EV chargers plus electric heat sometimes need 320/400 amp service, and we will run a load calculation rather than guess.

Can you replace a Federal Pacific or Zinsco panel?

Yes, and we recommend it. Those brands have a documented history of breakers failing to trip under fault conditions. Replacement with a modern load center is one of the most worthwhile electrical investments a Colorado homeowner can make.
