110.26

[buck33k]

Did'nt have a camera today so I made this drawing. Hope it gives enough details.

The secondary of the transformer does not extend more than 6" beyond the front of panel B.

Violation of 110.26(F)?

I don't think it's a violation. At least I've never been called on it and I've done similar many times before.

It's hard to tell from the drawing. Do you have any other measurements? I can see where this could go either way.

I don't see a violation. A transformer is electrical. Are you thinking of
"Foreign Systems?"

No, not exact measurements as this is from memory. I did note the secondary conduit did not extend much beyond the panel it was under....well under 6".

Conduits from panel A are crossing the "dedicated" spaces of panels B thru Z. How often does this kind of thing happen?

Often.

Yes. If the conduit exited the center panel and turned on the floor, I would'nt question it, but it comes from another source.

Good point.

All of your panels come from one source, transformer or not, The Service.
Honestly, I'd have to see a picture. That would be like saying that no conduits could pass over another panel within 6' of another panel.
"Foreign Systems" are piping, ducts,leak protection apparatus,or
equipment "Foreign" to the electrical system. Sprinklers must comply
with 110.26(F)(1)(C).

this is not a violation (unless the disco has a problem - can't tell cause there are no dimensions)

Your right, they all come from the same source. Ike made the point that conduit systems pass through the dedicated space of other panels often. That is also true but I wonder if that should be the case. That would interfere with conduit systems associated with their own panels. Maybe other electrical conduits could be "foreign".

Working space OK on the disco.

It's not foreign, it all comes from ONE source. If all panels are "Bonded"
propperly to the source. I don't see the safety issue. I must say, I do like
how you question it.

Buck,

110.26(A)(3) clearly allows the installation (2008 NEC) as long as the secondary is not

more than 6" beyond the front of the panel.
