Metal clamps around GEC

[Ken9876]

If you run a GEC without pipe or in a wireway and secure it with metal pipe clamps, would this be to code or would it violate the NEC and would it cause a choking effect if there was a fault?

From your description I picture worm drive radiotor hose clamps ?

Could you expand on your application/use ?

I'm guessing he is talking about maybe using a metal conduit strap for securing the GEC.

As long as it does not completely encircle the conductor I don't think there will be any significant change of impedance on the conductor.

I have seen it done with 3/8 inch one hole straps. Since we don't have 3/8 inch pipe, what else would they be used for?? :?

AC/MC cables.

3/8 one hole straps are used to secure M/C cable to metal studs

After reading the responses to the OP, I started looking around at the term.


GEC has a pretty thorough listing in the Index, I didn't see any refernce to this term, electrical choke. Is does exist in respects to combined usage of AC and DC service and component circuits at the electronic levels; the closet to the subject OP would be located at Article 250.94. Note (6) in respects to the proper clamp.

I'm sure there are other Articles but not when in respects to AC usuage only, IMO.
