I was reading the instructions on my new powerhead last night and it says its only to be used with a CGFI outlet. I know saftey first yadda yadda yadda. Is this a golden rule or just something in the instructions for liability sake? And if I do need to install a CGFI is it something a non-electrician could handle? I assume by looks of it its just turning power off to the circuit, pulling the old outlet, hooking the wires up to the CGFI outlet and sticking it back in the wall.
