Question;
When installing temporary lights and 120V 20A temporary receptacles in a building for use during construction is the wire feeding either the lights or the receptacles required to be GFCI protected?
Here is the situation.
A temporary panel was set fed by a permanent feeder.
12-2 NMC is fed from the panel to some temporary receptacles. The first receptacle is a GFCI which is connected so as to protect the ones after it.
12-2 NMC is also fed from the temporary panel to a permanent lighting circuit with temporary pigtail sockets w/cages.
The way it was explained to me years ago, is the purpose of the GFCI protection is not only to protect personel from harm resulting from damaged extension cords and equipment but also damaged or "pinched" temporary wiring, such as the 12-2. This is also why temporary wiring must be in the form of a cable assembly and not single conductors as it was in the past.
What do you guys think?
