Frequently asked questions
How do I know I need an upgrade?
Frequent breaker trips, no open slots, or planning an EV/addition are common signs. We assess for free.
Will the power be off long?
We minimize downtime and schedule the cutover to fit your day.
Is it permitted?
Yes — service upgrades require a permit and inspection, which we handle.
