Frequently Asked Questions

What size breaker does a hot tub need?

Most 240V hot tubs require a 50A or 60A GFCI breaker. Smaller 120V plug-in models use a standard 20A outlet.

How far can the panel be from the hot tub?

There's no maximum distance, but longer runs require thicker wire to prevent voltage drop. Runs over 50 feet may need to upsize from 6-gauge to 4-gauge.

Is GFCI protection required?

Yes. NEC requires GFCI protection for all hot tub circuits. The GFCI can be at the breaker, the disconnect, or both.

Can I plug a hot tub into a regular outlet?

Only small 120V portable spas can use a standard outlet. Most full-size hot tubs require a dedicated 240V hardwired circuit.
