Identifying The Source of Electrical Hazards

How to Prevent a Potential Problem with a Circuit that is not Properly Grounded: The terminations to the outlet and the connections of the power cord should be positively identified and verified. The 4 wire 240 volt outlet should have a ground wire attached to it and if the outlet box is metal or has a ground screw terminal then there should be a ground wire attached there as well ending up with a bond of all ground wires within the outlet box.
