Conduit just isn't acceptable here. In fact we hardly use any conduit. The odd straight length for am appliance socket (switch) and that is invariably PVC, not EMT. Equipment grounding is the connection to the ground of non-current-carrying conductive materials – e.g., cable trays, metallic conduits, junction boxes, transformer casings, and motor frames. The purpose is to limit the conductive material voltage to the ground. You don't need a wire to ground the switch, the mounting screws satisfy the requirement when used with metal boxes, and there is an exception that allows you to not satisfy grounding requirements if no grounding means exists for replacement switches.
I Was Asked The Question If Conduit Could Be Used As The Equipment Ground. We Ran Into A Situation Where A Control Panel Required 3 Phase, Plus A Neutral And A Ground. However, The Neutral Was Not Pulled And The Contractor Is Saying Thay Would Have To Pull All The Cables Out To Add The Neutral.Conduit must be installed to enter manhole perpendicular to manhole.

Bonding provides for a low-impedance fault current path back to the source of the electrical supply to facilitate the operation of overcurrent protection devices in the event of a ground fault.
