EMT connector grounding?

[Dennis Alwon]

I WILL BE RUNNING 1/2" emt in a warehouse for 10 lights i will use a egc so every junction must be bonded to the ecg if it has splices in ti. if i don't use egc i would bond the egc from the light to the box it inters?

That is correct

 

[Kyle1974]

If the conductors are spliced or if they are connected to a device or piece of equipment in or supported by the box.

No, this is false.

250.148, this article section is the same in 2005 and 2008.

Thank you for helping me clear this up Roger and the rest of the gang.

EGC????? and ECG?????:-?

I think he meant egc for both

I am sorry this is still bothering me. If the metal raceway is sufficient as a ground then the box is effectively grounded. If we don't pull an egc then we are fine however if we pull an egc we must ground the box if there is a splice. Odd.......

Also I am not quite sure about the commentary



The purple text, IMO, is saying that if the conductors are not splice to equip. in the box or not terminated to equip. in the box. The following sentence says an example is......Thus there must be other examples--- not sure what they are other than a splice without equipment in the box.

Dennis, I'm sure it's been proven that the EMT is a better EGC than a wire

type EGC, the NEC must feel this way or we would always have to run a wire

type EGC. I believe this is why the splice and connection to the box is required.
