Mc cable to panel

[ronball]

Is their any code that doesn't allow you to run mc branch circuits out of panel.

These would be surface ran up block wall.

Are their any special requirements.

ceiling is only about 30 inches above panel.

We do that often. You can buy 1 hole MC straps to secure it.

 

[ActionDave]

Do it often. Normal rules apply. Nothing special.

 

[electricalist]

Perfectly legal.
I like to run emt til I'm above the ceiling then set a 4 sq. Or if many circuits a small gutter. That's just my preference , I like how it looks plus I can leave some spare circuits to keep it simple and safe to add on.

I thought it wasn't good practice to run mc on cinder walls bc moisture can be a factor .
Physical damage I personality never like to run mc flush mounted when you can fun conduit and have it look better and you can install circuits in future .

Here in Austin, local ordinance prohibits the install you are describing in commercial applications.

I just got done with a restaurant that had some MC wiring in the basement and Yes it to was deteriorated especially where it touched the foundation walls!

Up in Toledo, Oh they required it because of mice from what I understand in residential.

I try and run conduit any chance I get

I forgot about Austin. We worked on a hotel. Remodel and had to open the wall above every panel and pipe up and out to a j box, Max 4 mc s no matter how big the box.

Max 4 mc s no matter how big the box.

What's the reason for that?

 

[electricalist]

I can't say that he gave a reference other than because he said so. My supervisor said what about,,,,,the inspector said 4 mc s no more. .
I will say this we had more to accomplish doing 5 floors than we had people. So it worked out better that way. My job was finding and fixing mistakes

 

[electricalist]

Originally every thing was in emt, maybe there was a reason we could use mc and he made it difficult.

augie47, That looks like a rats nest ! No connectors on 7 knock outs that I can see. It is work like this that makes you say "Its cheaper to do it right the first time, then to redo it later" As far as trouble shooting compare the pictured panel to one that is done in a neat fashion. Neat work makes trouble shooting that much easier.

... Max 4 mc s no matter how big the box.

I've been told that the reason for max 4 MC's is because each cable has an EGC and a 4 sq box gets crowded.

But that doesn't explain why you can't have more than 4 MC's in a 12 by 12. Or, why you can't have more than 4 MCAP's in a 4 sq box.

Augie's picture illustrates why I think City of Austin disallows MC in panels. The city code also requires MC connectors to have a stop to prevent the sheath from sliding past the connector into a box.

The NEC already has rules to prohibit what is shown in Augies picture it sounds more like someone in power in Austin likes pipe.

I have never used those, it might be good to stock a few.

That said I simply put a standard connector on the MC before I snake it down into the panel.
