I got that... but how many electricians wire 'two 15 amp legs' to each receptacle? If there had been a surge protector with a trip built in the unit would have tripped before zapping the wire behind the outlet... either way he needs to have a good marine electrician check all his wiring now... put some safeguards into the circuit, but due diligence in watching the electrical loads goes a long way.
