Signs you need an upgrade
- Breakers trip frequently, or you rely on power strips and extension cords everywhere.
- You're adding an EV charger, heat pump, hot tub, or home addition — 200 amps is the modern standard.
- Your panel is a fuse box, or uses breakers from a brand with known safety issues.
- Your home insurer asks about it — some carriers charge more (or decline coverage) for outdated panels.
What affects the price
- Amperage jump: bigger jumps need heavier-gauge service wiring and sometimes a new meter socket.
- Panel location: moving the panel, or one buried behind finished walls, adds labor.
- Permits and inspection: nearly always required; your utility may need to disconnect and reconnect service.
- Wiring condition: if existing circuits need AFCI/GFCI breakers or rewiring to meet current code, costs rise.
Safety note: panel work is not a DIY project. It involves the main service feed and must be done by a licensed electrician with proper permits and inspection. Expect your power to be off for several hours during the swap — most upgrades are completed in a single day.
