Panel Upgrades
When the panel is the bottleneck
If you are adding a charger, hot tub, heat pump or finished basement and every slot is full, the panel is the project. We size for what you are adding plus what comes next.
Zinsco & Federal Pacific
Known-hazard panels replaced with modern gear, including insurance documentation of the change.
Full Panel Replacement
New breakers, labeled circuits, grounding and bonding brought current, and an AFCI/GFCI plan that will pass.
Subpanels
Garage, shop, basement and ADU subpanels fed correctly with four-wire feeders and separated grounds and neutrals.
Permits & Utility Coordination
Permit, meter release, and Rocky Mountain Power disconnect and reconnect scheduled around your day.
Surge Protection
Whole-home surge devices installed at the panel to protect electronics, HVAC boards and appliances.
How a panel upgrade runs
A panel swap touches the utility, the AHJ and every circuit in your house. Sequencing it properly is the difference between one day without power and three.
- 1Load calculation and scope
We measure your actual demand, count circuits, and check the service conductors and grounding electrode system.
- 2Permit and utility scheduling
We pull the permit and book the disconnect so the crew, the inspector and the utility are lined up on the same day.
- 3Change-out day
Panel replaced, circuits re-landed and labeled, grounding and bonding corrected, AFCI and GFCI protection installed where required.
- 4Inspection and reconnect
Inspector signs off, power comes back, and you get photos of the finished panel with a legible directory.

Panel Upgrades FAQs
Panel upgrade questions
How do I know if my panel needs to be replaced?+
Full breaker slots, double-tapped breakers, rust or moisture in the enclosure, warmth or a burning smell at the cover, breakers that will not reset, a 60A or 100A service feeding a modern remodel, or a Zinsco, Federal Pacific Stab-Lok or Challenger label are all reasons to replace rather than repair.
How long will my power be off during a panel upgrade?+
Plan on most of a day. We schedule the utility disconnect first thing, work straight through the change-out, and are usually back on before evening. If you have medical equipment or refrigerated inventory, tell us and we will plan temporary power.
Do insurance companies care about Zinsco or Federal Pacific panels?+
Increasingly, yes. Several carriers in Utah will not write or renew a policy with those panels installed. We document the replacement with photos and the permit final so you can send it to your agent.
Is 200A enough for my house?+
For most homes, yes, even with an EV charger and a heat pump. Large homes with two chargers, a hot tub, a shop, electric heat or a pool sometimes need 320/400A. The load calculation answers it in a way that a rule of thumb does not.
Can you replace the panel without upgrading the service?+
Often yes. If the meter base, service conductors and grounding are in good shape and the amperage is adequate, a panel-only change is faster and cheaper. We look at the whole path before quoting.
