Does the GFCI in a spa panel require 4 wires in from the main panel to work? My situation is I have a Robobrew 65L that takes hot hot ground, but I want to GFCI protect it with a spa panel. Can i wire up a spa panel to plug into a 3 prong dryer outlet, or do I need to run a dedicated line with the 4 wire configuration (hot hot neutral ground) into the spa panel and then wire 3 out to my Robobrew?
