GFCI Wiring and Connections for Hot Tub Electrical Circuit Panel: Essentials for your installation, including the required GFCI ground fault protection and circuit wire size.
Hot Tub Electrical Circuit Panel Wiring
Electrical Question: I have a hot tub sub panel that has the ground and neutrals on a shared bar. I’m selling the house and the home inspector said to separate the ground and neutral but I only have one bar can I just simply add another? Is this common?
This electrical question came from: Shawn, a Homeowner from Anchorage , Alaska.
Thanks for your electrical question Shawn.
Wiring and Connections for Hot Tub Electrical Circuit Panel
- Some panels are sold this way but the inspector is correct, the electrical wiring for hots tubs does require separation between the ground and the neutral wires.
- An additional terminal strip or bar may be added, and I’m assuming that you will need a ground bar which will be mounted directly to the hot tub panel enclosure.
- The neutral terminal strip should not be bonded with the ground and should be insulated from the enclosure of the hot tub sub panel.
- The ground wire should then be separated from the neutral and the GFCI Circuit Breaker should be tested to make sure that it functions.
