I did this: I took a regular extension cord and cut the female end of it. Then I put a regular GFCI outlet into a plastic outlet box and attached that to the extension cord. Basically I have an extension cord with a GFCI receptacle on the end. They sell these GFCI adapters that construction workers use, but you DO NOT want to use them. They trip when the power goes out and will not reset when it comes back on. So if your utility disconnects your house for 1 minute, your tank will not restart! Guess how I found out. :-)
