Hi
I installed a whirlpool tub and I need to connect the pump. I know it requires a dedicated circuit but is almost impossible. I decided to use the washer machine circuit (is the only consumer). Anybody has an idea what would be the risks besides code violation?
In connection with this: the wire from the main panel to the junction box is an old 12 cupper, but the ground wire is probably 18 or so. Will it be a problem if I connect this with the ground from a different circuit in the house where I have a 12 ground?
Thank you
