I don't see Wiremold listed out specifically in 250.118, but (13), & (14) are vague. I don't know if Wiremold falls into either of these categories regarding whether it counts as an EGC?

I've always thought it didn't count as EGC, but not sure.
Any input or thoughts are appreciated,
Thanks!
 
They would have to be listed for grounding. All 386 says is for transitioning from other wiring methods methods a means for connecting an EGC must be there.
 
Number 14 is pretty clear that if the wiremold was listed for grounding then it can be used for grounding but if you transition to another raceway then you need a means to connect an equipment grounding conductor.

If the transition fitting is listed for grounding and you are transitioning to another wiring method that is also listed/permitted to be used as an EGC..?

Been a long time since I have looked into it, but I thought Wiremold surface raceways and most the common fittings are listed for use as EGC.
 
I have pretty much always used an EGC wire in Wiremold , but my new project has a fair amount of Wiremold that doesn't have an EGC conductor/wire.
Just trying to figure out if I need to add one.
Thanks
 
I've always used Wiremold as the EGC, as long as wire EGC's are properly terminated to it in boxes. Think of it as a mixed EMT and NM circuit.

If fittings are properly secured, why is it a problem? The spring pressure on them is sufficient, the biggest issue is if they should happen to pull apart.

A cord cap pushed into a receptacle isn't that much different other than it will pull apart easier in most cases.

A cord plug falling out of a receptacle breaks the EGC connection last.

True.

Also a broken off EGC pin on the plug means no EGC at all in the supplied equipment. I trust Wiremold to pass an EGC on better than a cord cap, especially 5-15/20 or 6-15/20's.
