Modifying a conduit body

[Thomas529]

Can a conduit body, such as an LB, be modified to accept more conduit than it was designed for. I am questioning the legality of a situation that I recently saw at our facility where a mallable iron LB had a hole drilled into the side of it, and a piece of 1/2" sealtite flex was installed. I am sure this is not allowed, but I am unsure what section of the NEC would be applicable for this instance.

That is not legit as the conduit body is not being used as intended by the manufacturer. I would cite a violation of 110.3(B). The installation is likely not in accordance with the listing or labeling instructions.

Geez, what a hack job, the lock nut was left on the fitting.

I like it

That's not hack. You do that so the fitting does not stick too far into the LB. It's too hard to get a hack saw down in there. Everybody knows that. Geeze, kids these days.

I have done it to get some signal wires where they need to go, but they did not carry any line voltage.

What is in the pipes in the picture?

This conduit is carrying the wiring for 2 machine E-Stop buttons on 24 Volt DC.

Ya got me there pops, I did not think of that.

The wiring in this conduit is actually the E-store wiring on this machine.

May not apply

May not apply

If it is part of a listed machine, then NEC does not apply.

we have a job now that fancy customer did not like the looks of weatherproof boxes and we ended up using 1-1/2" c condulets that will be drilled to accommodate a half inch seal tight connection. At that size ratio the install seams rigid to me but inspector may cite 110.3 (B)

I wouldn't worry about it.

 

[Thomas529]

It wouldn't be such an issue, but our plant is currently trying to get OSHA VPP Star, and we are trying to make sure we don't have any violations.

In that case I would probably just take out the LB and put a j box there.
