MC cable in raceways

[iwire]

Nice neat work, I have executed projects like this the same way down to using the scrap wire as a clip (sometime).

Yeah, it is not my first choice but it was handy, it works, it is strong and its above a suspended ceiling so.

I have a question why not use Brown/Orange/Yellow colored conductors when supplying a 480 volt feed to a disconnect?

The company will do that with large projects but for these one of deals I just order off the shelf cable.

I ordered the 3/3 On a Monday and I had at 5 AM Tuesday. Had I requested BOY I would have been waiting.

How do you read it?



Part of 300.15



The conduit terminates at the cable, therefore 300.15 requires a box or a fitting.

Fittings must be used as listed.


Remember, I do this all the time so I am 'on your side' but there are some code issues in my pictures.

You fail to include 300.15 (C), which is applicable to the situation you are referring to. I actually thought you meant 300.15 required the cable to terminate in a fitting inside the box.

I can't speak to every brand of MC cable but the 2-3 brands I buy here are all printed/labeled on the individual conductors under the armor. Just like any THWN-2 conductors are.

We get it both ways, it depends on the maker, sometimes on a separate clear ribbon, sometimes on the plastic wrap and sometimes directly printed on the conductors.

My position is the NEC requires the makers to provide that info, I don't believe the NEC tells us if it can be removed or not.

When I said 300.15 I mean all of it.

In my opinion C specifically applies to sleeves, not raceway systems so it does not apply to my pictures.

(C) Protection. A box or conduit body shall not be required
where cables enter or exit from conduit or tubing
that is used to provide cable support or protection against
physical damage. A fitting shall be provided on the end(s)
of the conduit or tubing to protect the cable from abrasion

Sometimes I wonder if some of you actually do electrical work, or you just like to argue about doing electrical work that you never do.

I don't feel it applies to your pictures either. We are referring to two different parts of the conversation, I think. If you had sized your raceway (actually chase) for 60% one conductor and pulled the MC jacket and all through the raceway, that is what my comments you are debating referred to. That isn't what you did. I have zero issue with what you did and I have done it just like that, and will do it just like that again as long as the AHJ doesn't bust me. .

Why is it so necessary to get so ridiculously picky here? Article states that MC is allowed to be installed in raceway. It doesn't say conductors stripped out of MC may be... I don't feel your question has any merit. For example, when you run SEU in a trench but it must be enclosed in a raceway where it extends up from the ground how do you do that with your same argument. Give me a break.

Avoiding an explicit and direct answer?

I'll answer yours...

First, Code explicitly permits the raceway to be installed incomplete for the purpose of protecting direct burial when it emerges from underground (BTW, it's USE not SEU).

Second, 300.5

(H) Bushing. A bushing, or terminal fitting, with an integral
bushed opening shall be used at the end of a conduit or
other raceway that terminates underground where the conductors
or cables emerge as a direct burial wiring method. A seal
incorporating the physical protection characteristics of a bushing
shall be permitted to be used in lieu of a bushing.

Your post count certainly backs that up. :happyyes:

MC stands for metal clad. If the metal is removed it obviously is not MC cable any more. It is now a group of insulated conductors which can be installed per their marking.

They do not have to be marked where the armor has been removed. It follows that the wires are still a member of the cable. Only when you remove all of the armor over the entire length does it cease to be an MC cable.

It cannot work that way.

If it is still not MC when you strip it to enter a panel what is it?

What article in chapter 3 applies to it?

What is the temperature rating of it?
