Hot Tub Circuit Requirements and Electrical Wiring

Can I use a voltage converter for a hot tub? My new hot tub requires 220volts and i was wondering if I could use a step up voltage converter from 110v to 220v and still work for the hot tub.


220 Volt Hot Tub
Question: Can I use a voltage converter for a hot tub?
I am having a hot tub installed on my back patio, it is 220 and I was wondering if I could use a step up voltage converter from 110volt to 220volt and still work for the hot tub?

Thanks for your electrical question Tristan.

Electrical Wiring for a 220 Volt Hot Tub

I do not recommend using a voltage converter for a hot tub circuit, because Hot Tubs require a dedicated circuit, and this circuit must provide GFCI protection. A typical hot tub circuit will be a 50 or 60 amp 240 volt 4-wire circuit depending on the size and specified requirements stated in the installation manual.

    I recently purchased a 110 volt plug and play spa. The cord has a GFCI built in to the plug. If I wanted to convert to 220v, could I use a voltage conversion box since it already has the GFCI on the original 110v cord?

    • Dave Rongey says:

      Hi Raine,
      Converting The Voltage of a Plug and Play Spa
      You will need to refer to the specific plug and play spa that you have to see if it provides a dual voltage capability of 110volt and 220volt. If the spa has been built specifically for 110volt then you should not attempt to convert the voltage, otherwise you will risk permanently damaging the spa and it will become a very dangerous shock hazard.
      Please refer to the owners manual for your spa and the specifications.
      Be Safe,
      Dave
