I am bringing my NEC book home with me for the weekend. I have to find a place to mount a new 400amp electrical subpanel on three sets of three floors for 4 like facilities. There is a small electrical closet that already has two electrical subpanels in it mounted on the back wall where I may be able to mount the new subpanel. Mounting the new subpanel on the side wall of this small room should work since I will have NEC clearance in front. I am worried about the back wall where the subpanels on the back wall are mounted becomming a NEC clearance violation from the side of the new subpanel.

I am also hoping blue lube was used so that I can reuse the feeder conduit and branch conduit for the electrical subpanels. I have to get the electricians in there and pull the main distribution panel and some subpanels apart to see if I have room to pull some new circuits.

I also must find out if the electrical subpanel could be mounted in the room designated for the telephone closet.

I know the Janitor's Closet must be a NEC code violaton since a wash sink is in there.

I have to find a place to mount the new electrical subpanel in order to estimate costs for the job.

No, just change the name on the door. :)

You either have the required work space or you don't.The name of the room should not matter.As to the janitors closet ,why not ?

Sink or not you can put the panel pretty much anywhere you want that has the required working space.

I learned this weekend after reading the NEC that the Janitors closet is out since this room is used for storage, even though nothing is stored in there presently.

The telephone closed would probably be a violation with the AHJ since the telephone circuits would be running above the electrical subpanel when the telephone guys need to get in there to work.

I am totally blown away again it appears since I don't believe I can mount the electrical subpanel against the side wall of the electrical closet since 3 feet of working space is not on the side of the electrical subpanes as you would run in to the wall where the front door is and this is an ungrounded wall made of brick (condition 1 in the NEC).

If nothing is stored in the work space i see no problem.Now if after its finished and passes inspection and they violate the space then let the fire marshal deal with them.Not too long ago i was working in a large gas botteling plant that had tanks sitting right in front of the MDP and subs.Had to ask them to move them so i could even open the panel doors.Not your problem if space is misused after you leave. ;)

It sounds like you are going to try and use an already occupied raceway???

If so, you may have more than 3 ccc and you will need to comply with ampacity adjustment.
It also sounds like you may be trying to put 10lbs of --- in a 5lb room... if you catch my drift.
Why is it that the electrical rooms/areas are given such little thought in regards to size, etc...????

Great question,we had one that almost was not wide enough to fit the panels.It was actually 1/4 inch to skinny if the inspector had pushed it.2 panels 1 on each wall.

110.26(F) permits electrical things above the panel. Communications circuits are electrical things, since they are governed by Article 800.
 
Re: Electrical Panel in a Telephone Closet

Thanks Ryan and Jim. This is an existing dwelling, so the headroom can be less than 6 1/2 feet as I think you indicate.

I'll consider the Janitor's clost and telephone closet also.
