Hiring a licensed electrician for generators, hot tubs, saunas and EV chargers
Most of the big-ticket products on this site plug into your electrical panel one way or another. A standby generator, a 240V hot tub, a traditional sauna heater and a Level 2 EV charger all need a dedicated circuit, and most need a permit and inspection.
Hire right once: Ask the electrician to check your panel's capacity for every big load you're planning over the next few years, not just this one. One panel upgrade or subpanel costs less than two.
Before you hire, check:
- A current license on your state or local licensing board's lookup
- That the quote includes the permit, inspection and any load calculation
- Panel space and service size for the loads you'll add later
What they do for these products
- Standby generators: install the automatic transfer switch, wire the generator to it, and coordinate the gas or propane connection (often with a plumber or gas fitter). Many generator dealers include this.
- Portable and battery generators: install a power inlet box with a transfer switch or a panel interlock so you can back up chosen circuits safely. Plugging a generator into a wall outlet ("backfeeding") is dangerous to you and to utility workers.[2]
- Hot tubs: run a dedicated GFCI-protected circuit (typically 240V/50A for acrylic tubs) and a disconnect within sight of the tub, per NEC Article 680.[1]
- Saunas: run the dedicated 240V circuit sized to the heater's nameplate and the maker's instructions; 120V infrared cabins usually need only a dedicated outlet.
- EV chargers: install a Level 2 circuit (NEC Article 625) and, where the panel is full, a load-management device or panel upgrade.[1]
Licensing and permits
Electricians are licensed by the state in most of the U.S. and by the city or county in some places; check the license on your licensing board's website. New circuits, generators, transfer switches, hot tubs and EV chargers usually need an electrical permit and inspection under the edition of the National Electrical Code (NFPA 70) your state has adopted.[1] Standby generators may also need a gas permit and setback clearances from windows, doors and property lines set by the maker and local code.
Questions to ask
- Do I have the panel capacity for this, and did you do a load calculation?
- Is the permit and inspection included in the price?
- For a generator: transfer switch or interlock, which circuits are covered, and who handles the gas line?
- For a hot tub: where will the GFCI disconnect go, and what's the trench or conduit route?
- For a sauna: what breaker and wire size does the heater's manual call for?
- For an EV charger: can you add load management instead of a panel upgrade?
- What's your workmanship warranty?
