I want to install a 5500W 240V heating element in my HLT and BK to supplement propane. I will only be running one heating element at a time. The easiest route to power the heating elements is to run 25' of 10/3 wire from my dryer outlet to my brewing station. The dryer outlet has a 30A double-pole breaker. My question is how do I wire 10/3 wire to a four prong dryer and GFI protect it?
