Not electric-savy here
Waiting for new 110v Plug n play hot tub to arrive. But planning on plugging it into the GFCI outlet on the side of my swimming pool equipment panel.
However, in the pre-delivery instructions it says "A GFCI cord is supplied with your spa. Your spa must be wired with a GFCI either on the cord
or on the outlet, but not both."
Why would this be? Does it present any risk?
And what would be the most cost effective solution? Incidentally I do have a couple of available 'slots' in my pool equipment panel.
