Hot Tub, Spa and Pool Wiring

We wire hot tubs, spas, and pool equipment from the panel to the tub, with the protection the electrical code calls for.

Most hot tubs that seat several people run on 240 volts and need a circuit of their own, often 50 amps. Smaller plug-in models run on a regular 120-volt outlet with GFCI protection. The spec sheet that comes with the tub says which kind you have, and it's the first thing we ask for.

What does a 240-volt hot tub need?

  • A circuit of its own from the breaker box, sized to the tub's label.
  • A shutoff box with GFCI protection, mounted where you can see the tub and at least five feet from the water.
  • Wire in conduit from the shutoff to the tub, run under the lawn, along the house, or beneath the deck.
  • Bonding, which ties the metal parts around the tub together so they stay at the same voltage.

Jesse planned this setup and Logan wired it:

Jesse was professional and knowledgeable during the inspection, planning and estimate. Logan did excellent work wiring up my auxiliary box and connecting the hot tub. I couldn’t be happier.

When the panel has to come first

A hot tub is one of the biggest things you can add to a house, electrically, and an older or full panel may not have room for it. In that case we price a panel upgrade alongside the tub wiring. Jesse put it plainly on Zach S.'s quote:

… Jesse and the team replaced our breaker panel, bringing everything up to code, and also wired our new hot tub. We knew the breaker panel needed to be replaced prior to the quote, and one of the best things we received from 4 Point Electric was a statement on the quote that read, "We wouldn't feel comfortable wiring the hot tub without updating the panel." …

Pick the spot before the tub arrives

The distance from the panel, whether the wire runs under a lawn, a patio, or a deck, and what the tub sits on all shape the job. If a deck builder or a landscaper is involved, we work around their schedule so the conduit goes in before the patio is poured. A spot near the house usually means a shorter run and a lower price. While the trench is open, it's an easy time to add path or patio lighting.

After the tub is running

The GFCI in the shutoff box has a test button. Tub makers recommend pressing it regularly, usually once a month, to make sure it trips; then reset it. If it trips on its own and won't reset, that points to moisture in a connection or a heater element going bad, and it's worth a call before you keep using the tub.

Pools and pool equipment

A pool can have a pump, a heater, lights, and an automatic cover, each on its own circuit, all bonded together with the water and the metal around the pool. Send us the full equipment list and we'll price the whole setup together.

Before the tub is delivered

Send the tub's model or spec sheet, a photo of where it will sit, and a photo of your breaker box.
