Hot Tub Electrical Requirements: What Your Electrician Needs to Install
Congratulations on the new hot tub! Before you fill it, the electrical has to be done right. Here is what to expect.
Circuit size
Most 240V spas require a 50 amp GFCI-protected circuit; larger models with multiple pumps and heaters need 60 amps. Plug-and-play 120V models use a dedicated 20 amp GFCI circuit.
Disconnect location
A disconnect must be within sight of the tub, at least 5 feet away and no more than 50 feet. This lets anyone cut power in an emergency.
Wire and conduit
Copper conductors in PVC or liquid-tight conduit, buried at proper depth, connect the disconnect to the spa pack. Bonding of the tub, nearby metal and perimeter is also required.
Permits
Hot tub circuits require a permit and inspection. We handle both.
Does my panel have room?
A 50–60 amp circuit is significant. If your panel is full or 100 amps, we may recommend a panel upgrade or sub panel.
