gfci protected wiremold

[copper chopper]

a ? was asked myself by an apprentice. Do i know where in the code it says, when putting single circiut wiremold on gfci protection (breaker or load side of outlet) that you can only put 5 outlets in the wiremold.... I had to say no, so has anyone ever heard this and if you have please give code articles of where the heck this might be.

I would check the manufactures instructions.

Nothing in Article 380 talks about GFCI protection, one way or the other.

Maybe he was vaguely remembering 220.14 (H).

Could be, because that was my other guess is that the load would be high for the GFCI receptacle.

Generally there is no code restricting how many receptacles are put on the load side of a GFCI, but some manufactures might have a restriction, and if this is commercial then you are limited to the 180va per strap rule.

Just because these receptacles are in Wire Mold is not an issue.

GFCI receptacles do not have any OCPDs in them and the circuit PCPD would protect the GFCI receptacle at its rating, all 15 amp GFCI receptacles are rated for 20 amp pass through.

Why some GFCI manufactures limit the amount of receptacles is more of a problem of capacitive coupling in the conductors then because of load, this has never made sense to me since a 100' run with only one receptacle on the load side will present more of a problem then 20 receptacles in a string just 20' long?:?

We're lucky if we can get the instructions with proper grammar and spelling; forget about any electrical theory.

Yes I know, I was just simplifying my answer.

Jeez, what part of this do you not understand?

I think you posted those instructions upside down...

Both of the above replies made my morning :lol:. Then again, as my wife tells me, I'm easily amused.

Regarding the OP: is there any manufacturers limitations on the devices attached to a GFCI breaker? I've never noticed any.
