One of our jobs just got turned down because they didn’t use a sealed lock ring coming into the CT cabinet; inspector told the foreman there is some sort of split gasket you can use on the exterior of the cabinet, but I’ve never seen it. Anyone familiar with this or have you seen a split gasket that can be installed ? My internet searches are coming up empty.

I've never heard of one. I am curious though, if a split ring is acceptable to the inspector, why not some pure silicone sealant?

I'm assuming this entry is on the side of the CT cabinet, but where is it, near the top, bottom, ... middle?

It’s at the very bottom side, so I’m not sure why they’re making a fuss over it, but I’m not there to argue and we’re just trying to get them to give us temp power.

Two things and not sure what you mean by split. First look at Roxtec. Very useful and IP68 for goofball connectors. Second is of course cord connectors but you still need access on one end with either approach. No way to put them on once the cable is in.

I thought if the conduit comes in at a level below live parts inside then it did not need to be a sealed type of installation.

As the others said, this is entirely legal if below terminations.

It may be worth your time to educate the inspector, the time spent doing that may be less than the time spent looking for an unnecessary sealing lock ring. As well as the fact he will be correctly inspecting future projects.

We'd probably consider this a battle worth fighting if it came to it in our shop, as we build A LOT of exterior services with penetrations in the sides of cabinets.

No, I know that it’s legal, it’s just a situation in which I didn’t want to get in a pissing contest. Some inspectors are less interested in learning what’s right versus just being “right”. If I were there, and face to face, I’d argue it, but I’m six hours away.
