Heat pumps, EV chargers, induction ranges and hot tubs all pull hard. Here's how to tell if your service size is the bottleneck — and what an honest panel upgrade quote should include.
- Signs your service is undersized (breaker trips under load, dim lights on start-up, no room for a 240V circuit)
- What a panel upgrade actually covers: service mast, meter base, grounding, permit, ESA/AHJ inspection
- Why a load calculation matters more than the amp number on the sticker
