plc noob

In my plant we have a lot of pvc coated mc cable for branch circuits and feeders ran in cable tray.

I have an application where it would be helpful to run mc cable as there is not much room for conduit.

The circuit will be fed from a mcc and will terminate at a disconnect on an outside wall.

I want to know if i can run the mc and strap it to the wall or to strut on the wall and be code compliant.

I am located in atlanta georgia and this is in a heavy industrial manufacturing plant.

But can it be strapped to the wall?

Or does it need cable tray?

this is pvc coated,chem resistant and uv resistant.

What does your boss say?

If the cable is not subject to physical damage where you plan to install it, yes it can be strapped to the wall.
330.10(4) permits it to be installed EXPOSED.

It is in a locked utility room with nothing stored on that wall and a main beam is in front of it.

Is there a height requirement for the horizontal run strapped to the wall?

Total length will only be about 15 feet.

Any special requirement of the strapping lengths/spacing?

mattsilkwood

take a look at article 330.

yeah plc noob you can run it to the wall, tie wrap it to another conduit, put it in a cable tray, you can even run conduit up the wall and drop the mc down in to it. no problem. just make it look good.

And you don't even need to use an anti-short!

Are you sure it is not type AC cable? It is more common in industrial environments.

You can't use a conduit as support for a cable except under certain circumstances, see 300.11(B).

Oh so this makes it legal?

So what? That doesn't mean it's NEC compliant. Just because something passes doesn't mean it's correct. Inspectors are people too, they do miss things from time to time.

sparkyboys

exactly. its all in how its done. if its seeable,then they will catch it. if not, then on with the rest of the job

manchestersparky

I working on not missing things

A slow economy has helped me with this, as I have more time to do my job now. Some jobs the longer I'm there the more nervous the contractor gets

sparkyboys

good. but every inspector misses things, not saying you are not good at what you do, but only the obvious things are caught

and that is another reason why i stay calm

Keep in mind that whether or not the inspector catches a violation does not relieve the electrical contractor, and ultimately the electrician, of the legal responsibility to install the wiring to code.
