Question

Does a self grounding duplex receptacle need to be grounded to the back of a metal box, with no metal conduit?

Answer 1

If u don't have metal conduit it would not do any good to  connect it to the box. If your receptacle is self grounding leave it as is .Check the wiring maybe u have a ground wire in the cable itself.

Answer 2

I always ground everything. Pigtail the ground wire to the box and the receptacle. Especially if there is no grounded pipe connected to the box. Better to be safe. I believe NEC 2008 requires grounding metal boxes in 250.110

Answer 3

The receptacle needs to be grounded. - So does the box.

If The rec.'s listed as self grounding, it bonds to the box if properly installed.

If there's no metal conduit or cable jacket to supply a grouind,

then the ground wire of your feeder should be connected to

the metalic box to ground both.

Answer 4

No.  But you should have a ground wire hook to the box from the breaker panel.  Or you could hook the ground wire up to the receptacle which ever is easiest.
