Breaker Box Clearance
« on: December 16, 2018, 10:13:07 AM »
Hi guys.

Wondering if someone with better knowledge of residential electrical code could help out (I know some industrial but mainly around 480).  I tried searching the internet and NEC at the library but I couldn't decipher a clear answer.

I have 2 200 amp breaker boxes in my basement.  They are currently in the "gym" and the cubby they're in "freaks out" my wife.  Previous owner walled in partially, which I was told is out of code. 

My question, what is acceptable to do to cover this area?


-Boxes are ~40 inched edge to edge
-As you can see this is also where my internet comes in (in AT&T's infinite wisdom I have to keep their router as a gateway hence the 2nd router which is going to be relocated).  My coax also comes in here (no internet or satellite of course) so I would like to be able to access this area for main power in, fiber in, running circuits to panels, and eventually, hopefully, solar power coming in.

My question:

-With the boxes wider than a 36" door, I assume cannot use in this situation?
-How much space has to be in front of panels?  I assume when working on it's 48"?
-Any other items that would need to be done?

The space has to be 30"x36" deep, per IRC E3405.2, "Working clearances for energized equipment and panelboards."

Thanks bacchi,

Looks like I have to do a full door then. 

I am thinking two folding doors for total 48" opening.  Like these:

(checking habitat for some used ones of course).

Thanks for the clear answer!
