GFCI Used In Lieu Of Ground

Question:Under what condition can a two-wire receptacle be replaced with a three-wire receptacle, when no ground is available in the box?
Answer:[406.4(D)(2)(b)] A non–grounding-type receptacle(s) shall be permitted to be replaced with a ground-fault circuit interrupter type of receptacle(s). These receptacles shall be marked “No Equipment Ground.” An equipment grounding conductor shall not be connected from the ground-fault circuit interrupter type receptacle to any outlet supplied from the ground-fault circuit-interrupter receptacle.

[406.4(D)(2)(c)] A non–grounding-type receptacle(s) shall be permitted to be replaced with a grounding-type receptacle(s) where supplied through a ground-fault circuit interrupter. Grounding-type receptacles supplied through the ground fault circuit interrupter shall be marked “GFCI Protected” and “No Equipment Ground.” An equipment grounding conductor shall not be connected between the grounding type receptacles.

Note: GFCI protection functions properly on a 2-wire circuit without an equipment grounding (bonding) conductor, because the equipment grounding (bonding) conductor serves no role in the operation of the GFCI-protection device.
CAUTION: The permission to replace nongrounding-type receptacles with GFCI-protected grounding-type receptacles doesn't apply to new receptacle outlets that extend from an existing ungrounded outlet box. Once you add a receptacle outlet (branch-circuit extension), the receptacle must be of the grounding (bonding) type and it must have its grounding terminal grounded (bonded) to an effective ground-fault current path in accordance with 250.130(C).

    Power To An Out Building

    Question: Can an outbuilding be powered by a subpanel in another outbuilding or must power come from the main service panel at the house?

    Answer: It is permissible to run a circuit from the sub-panel in the garage to the shed. It will require a disconnecting means (toggle switch is acceptable) in the shed in accordance with 225.31 and 225.32. Also take a look at 225.3 and its exception. A separate ground rod at the shed is not required because this is a single branch circuit and not a feeder. See 250.32(A)
