Hot tub electrical requirements
A 240V hot tub is wired from your electrical panel through a GFCI-protected disconnect near the tub. The electrical code (NEC 680.44) requires GFCI protection on any outlet that supplies a spa or hot tub, and a shutoff within sight of the spa, at least 5 feet away (NEC 680.13 and 680.41).
Is your panel big enough?
Whether your panel has room for a hot tub comes down to a load calculation: what your home already uses plus the spa. If it doesn't, see our page on electrical panel upgrades.

Frequently asked questions
What electrical does a hot tub need?
A 240V hot tub needs a circuit from your panel, a disconnect within sight of the tub and at least 5 feet away, and GFCI protection, which the code requires on any outlet supplying a spa. When the job needs a permit, we pull it.
Does a hot tub need a GFCI?
Yes. The electrical code (NEC 680.44) requires GFCI protection on any outlet that supplies a spa or hot tub, and that covers hard-wired spas, not only plug-in ones.
How far does the hot tub disconnect have to be from the spa?
At least 5 feet away, and within sight of the spa or hot tub, under the electrical code (NEC 680.13 and 680.41). The same maintenance disconnect can also serve as the spa's shutoff.
Will I need a bigger electrical panel for a hot tub?
Not always. A load calculation compares what your home already uses plus the spa with what your panel and service can carry. Many homes have room; some need a panel upgrade first. Ask us to look at your panel when we quote.
How much does hot tub electrical installation cost?
Every job is quoted before we start, and quotes are free, so we don't publish a flat price. Three things set it: how difficult the labor is (for example, how far the tub sits from the panel and how the wire gets there), how long the job takes, and the cost of materials.
Do I need a permit to wire a hot tub in San Diego?
In the City of San Diego, adding to or altering your wiring needs an Electrical Permit, issued only to a licensed contractor or the property owner. When your job needs a permit, we pull it.
