Romex in conduit to panel

Strapping for the nm?

Do I have to get UL approval when I drill holes?

Electric,

According to an ex-employer,
one hole for one cable,
no matter what size the hole!

We didn't see eye-to-eye! :smile:

Yikes! I couldn't even imagine!

One hole or 10, ...
If you were to make the same holes in load-bearing-wall studs,
you would have to reinforce them.

Larry,
Good point, and good trade practice.
But I don't think it is a code issue.

My remark about about UL approved "holes" was in JEST.
Estoy hacienda una broma! :roll:

While it seems there are plenty of violations to go around for this installation, I just wanted to throw this out there for my own understanding?


Jim W in Tampa States: ?If its over 2 feet then derate comes into play?

And

Twoskinsoneman states: ?Also funny to comply with the exception the raceway has to be 18" but if more than 24" you have to derate...?


As I understand this?
This could easily comply with the NEC as far as conductors in proximity and may NOT be a violation of Section 310.15(B)(2)(a).

We can only see what is in the photo and have no information on the individual circuit lengths, and whether or not the individual circuits are subject to additional conductor proximity.

As I understand this?
The exception to Section 310.15(A)(2) permits the conductors to be in proximity for as much as 10 feet (if conditions are met?) without considering the requirements of 310.15(B)(2)(a).


It appears to me that not enough information is available to call this a violation for proximity (bundling)?

I'm not convinced there is a violation here either.

Whenever poosible I discuss things with the inspector. Sometimes niether of us knows exactly what an answer may be. The time to figure these things out though is early in a project. And as Pierre said, he isn't inspecting what might be, hes inspecting what is there now.

Maybe, maybe not, but there is a reason framing inspections are done after plumbing, mechanical, and electrical rough-ins are completed.

 

[eljefetaco]

just because it is neat doesn't mean it's right.

sealing the raceway

what would be used for sealing the raceway to prevent blow torching?

Iaov,

In your post #125 you state: "I'm not convinced there is a violation here either"


... For a conductor proximity violation: You would be spot on ! (It is undeterminable from the information provided...)
