SEU PVC sleeve

[Jhallelec]

Has anyone ever been failed for installing a 4/0 SEU cable in a 2” pvc from meter to a LB as a stub into the house and converted over with a FA connector.

Just guessing…but I am thinking that one of the issues maybe that the 2” LB is not big enough for the 4/0 SEU. Also there may be an listing issue for converting from the FA to a SEU Cable connector.

I doubt there are any instructions or listing documents prohibiting threading a camp connector into an FA, but one could argue that the Connector needs to bonded and is not.

Are you using the connector for 312 5 C ?

The issue is usually that the 5X SE cable minimum radius of the bend in the LB cannot be maintained. An elbow in lieu of the LB solves that problem.

Which would be an interesting turn into the house from an outside meterbase without some big ugly sheep hearders hook to contend with.

Oddly enough that same bend of the SEU inside a standard wall depth doesn't really gain you that much as far as the bend radius either.

I have oversized the LB before to make it large enough for the 4/0 SEU!

What is the acceptable bend radius on 4/0 SEU cable?

Did the inspector give any insight as to how to resolve the issue?

There are ways to do it without the Shepard's hook and still use the code compliant elbow.

If a 4/0 SEU cable is traveling down an outside 3 1/2"deep wall, are you still not having to make as sharp a bend to turn it 90 degrees out?

A code compliant radius bend of the SEU wouldn't fit inside the wall either if there wasn't there wasn't a brick void or some other gap between the outside wall and the back of the meter base.

I just have a hard time believing the inspector failed him for bend radius seeing as how we are discussing a cable installation and not individual conductors that are replaceable when pulled through conduit.

If we had to maintain the bend radius of the conductors, we wouldn't be able to bend them 90 degrees and terminate them in the meterbase.

Which he's going to have to do to make the terminations.

You're correct that in some installations an elbow may not be a suitable replacement for an LB due to the length of the sweep.

SEU has individual conductors that are labeled as one of the types permissible in any Chapter 3 wiring method, if I'm not mistaken? In which case what's wrong with using a cable clamp at the house end of the PVC stub and stripping the SEU jacket inside the PVC? The cable clamp becomes a conversion fitting from cable to PVC.

His inspector seems to be very "Code oriented" and it's likely the individual conductors would not meet 314.28 with a standard PVC 2" LB.

There's 314.28(A)(3), so what's the typical marking on the interior of a 2" LB? If it's 3 @ 4/0, then it's fine. If it's less, then I agree a 2" LB is sized too small for the application.

Table C.11(A) for compact conductors with XHHW insulation says 2" PVC Schedule 40 allows up to (5) 4/0 conductors. So that at least makes it plausible a 2" LB would be marked for (3) 4/0 conductors.

Per the "tech drawing" available near the bottom of this page, for Cantex 2" LB, it's (3) 4/0 XHHW. So 314.28(A)(3) would be complied with.

My point was, even without an elbow or LB fitting at all, if the cable itself is inside of a 3 1/2" void between the studs in the wall, your going to have to bend it sharply to be able to terminate it into a meterbase, service disconnect or whatever is on the outside wall you're trying to get into.

Especially if the equipment is mounted directly on the outside wall without that added length of a brick void or the like to allow you to make a sweeping bend to the outside.

The inspector said the bend radius is wrong. If you use a sill plate the bend radius is even smaller.

 

[jap]

I read up on this and evidently there is a rule to the bend radius I wasn't aware of for the cable, so, I stand corrected.

That's what I get when I start jabbering without looking things up.

I need to re-read "Charlie's rule" at times.

I assumed that was his issue and I have to agree with him. Many inspectors will let it slide. My own home has #4/0 SEU in a 2" PVC LB that somehow passed inspection.
