Water and Electricity Need Extra Protection
Hot tubs pull a lot of power, usually a dedicated 240V circuit of 40 or 50 amps or more, and they sit in water. That’s why the circuit needs GFCI protection, and why code requires a disconnect within sight of the spa, at least five feet away from the water.
Your panel has to have room. A big spa can be the load that tips an older 100 amp service over the edge. We run a load calculation before quoting and tell you if a sub-panel or upgrade is needed.
Outdoor runs need protection. Wiring to a spa across the yard has to be buried at the right depth or run in protective conduit.
