There's No Grounding Conductor in Disconnect Switch and Circuit Breaker Enclosure

It happens man. I see it all the time. Machines vibrate, connectors separate, you lose your ground. It's just bad practice IMO.

I am not a huge fan of EMT in factories. I just see too many times when the connectors have come apart to be comfortable with it. But, as long as everything is tight EMT makes for a fine EGC. I just am not a huge fan of emt in factories.

Question. Suppose a conductor will be used as an EGC, then does that mean if there’s a fault somewhere, the fault current will go to the EGC and the raceway at the same time? Wouldn’t that be parallel paths?

why would it matter? the idea is to get enough fault current to open the OCPD. it does not matter how many paths it takes.
