im doing a service and im installing emt conduit from load side of service switch to a panel.
my intension is to run emt with set screw connectors steel both connectors and couplings.
install bonding locknuts at both ends.and not pull an egc in the conduit.
engineer says {now we both put this design together so its a friendly debate} that if we use set screw connectors we have to install a egc because set screw does not make an effective ground fault path. but if we use compression connectors and couplings we dont have to install an egc.
but still have to bond conduit to enclosures with bonding locknut .
