When using a metal junction box, eg handybox for a switch,
is it acceptable code to:

A - Just ground the metal box and rely on the switch getting
grounded by being fastened to the box

B - Just ground the switch and rely on the box getting
grounded by being fastened to the switch

C - Both must be grounded using wire?

Thanks all.

*With switches, the BOX must be grounded - the switch grounds to the
box.

OK, so now we have the switch grounding question
resolved. But there was mention of a difference for
receptacles? So, what is the rule for a receptacle
with a metal box? And why would one be different
than the other?
