Installing GFI Hot Tub Electrical Wiring and the GFI Circuit

Hot Tub GFI Wiring

Electrical Question: I have a Hot Tub requiring a 220 hook up.

  • Should the wiring be copper and the GFI copper?
  • An electrician says the GFI doesn’t matter as far as aluminum vs. copper.

This electrical question came from: Vale, a Homeowner from Cobb, California.

Thanks for your Home Electrical question Vale.

GFI Hot Tub Electrical Wiring and GFI Circuit

  • Most hot tubs clearly specify that copper wiring must be used for the installation.
  • The GFCI circuit breaker must be compatible with the copper wire as well, as they typically are.
  • A dedicated 4-wire circuit is typically required containing:
    • a separate neutral wire
    • and a separate ground wire.
