Welcome to our forum.
Can I get away with mounting the GFCI breaker in the main panel and just have the emergency disconnect switch in the spa room, or is there a maximum safe distance between GFCI and load?Also, I don’t want (and the inspector probably wouldn’t allow) the sealtight conduit from the disconnect to be ran across the surrounding walkway to the spa. The flooring is concrete, so I have to run it in/and on the surface of the walls..If more of the circuit has to be exposed other than the maximum allowed sealtight length (6' ?), should I use hard PVC conduit and watertight boxes, before the sealtight? Or daisy-chain sealtight lenghts with watertight boxes in between?Don’t have the spa yet, but I am hoping that the electrical entrance will be close enough towards the back to allow the flexible stuff to be ran from the back wall/spa corner intersection.
You are correct about your sealtite. It's meant only for the last few feet outside the spa, and to encase the wire inside the spa cabinet to the electrical connection. Also, you can use an inexpensive 60 amp a/c non fused pull box (under $10) for your disconnect if you put your GFI breaker in your main panel.Brewman
What you save on the Box....I think you make up for with GFI on your main .....Lowes, Home Depot both have units that have both for about $80.00
There are not a lot of sources for this capacity breaker- in fact the Sqare D "pro" series was my only choice, therefore for me it made sense to put it in the main panel, which just happened to be a square D pro panel.
