Receptacles installed within _____ of the outside edge of a sink be GFCI protected.

All ungrounded conductors of a branch circuit to be disconnected simultaneously at the point the branch circuit originates

Receptacles shall be installed face up on the counter-top surfaces or work surfaces.

The purpose of the grounding electrode system is to carry current for faulty circuits in the building or between the building and the utility transformer.

The path through the earth is not an effective ground-fault return path:

All 120-volt, single phase, 15- and 20-ampere branch circuits supplying outlets installed in
recreation shall be protected by a AFCI:

If the black and red conductors of the 3-wire cable are connected to the same phase in Panel A the neutral conductor must carry the unbalanced current

If the black and red conductors of the 3-wire cable are connected to the same phase in Panel A the neutral conductor must carry the unbalanced current

3-wire branch circuit will have more voltage drop in the conductors

In case of 3-wire branch circuit, if the neutral conductor opens this results in possible burnout:
