408.36 F

[sparky_magoo]

I recently installed two square D 125 amp main lug sub-panels in a detached building at a residence.
I back-fed the first panel with a 60 amp two pole breaker. This serves as the disconnecting means for the detached structure. I came out of the first sub-panel on the main lugs and landed this feeder on the main lugs of the second sub-panel. Both panels are full because of customer additions.

I just read 408.36 F and it tells me the back-fed 60 amp breaker requires an additional fastener to hold it in place. I haven't stumbled accross this requirement before and have never used an addtional fastener. Have I been wiring my sub-panels incorrectly?

Re: 408.36 F

Anytime you backfeed a breaker it must be fastened in place.

You should be able to get a clip or screw for this purpose from the panel manufacturer.

This is not a new requirement.

I just looked at this section in the '02 book, because that's the most recent one I have in electronic format. (My '05 is out in the truck and it's raining, so it's gonna stay in the truck for now) 408.36F in the '02 is all about minimum spacing requirements, so I can't really respond to your query. I just wanted to say this, because I know somebody will : What's a "subpanel"??

Square D sell the breaker retaining clips. They have different ones for different panels.

I'm using the '05 codebook, even though the house is under the '99 code.

It's 408.16(F) in 2002 and 384-16(g) in 1999.

What is a subpanel?

A subpanel is simply another piece of load side equipment (250.142(B)).

The wiring to a subpanel is treated no differently than the wiring to any electrical equipment on the load side of the service disconnect.

I just found the product I need in the Square-D catalog. I should have looked there prior to making a fool of myself (again) on the forum.

I know that. Just trying to fit in, by asking silly questions, over-analyzing things, and beating a dead horse.

This is the place to do it. It wasn't a stupid question at all.
