subpanel clearance

Knowing that breakers from a subpanel can't be more than 6'7" off ground and that there needs to be 36" clearance in front of the panel what about the sides of the panel? I've read 30" total in this forum and 30" to each side of the subpanel in other forums. If either side needs 30" clearance could an exterior door be located 30" or less from panel? The answer to this is very important as I have limited space and a workbench that may be affected. Any information would be appreciated.

The 30" required can be anywhere in front of the panel. It can be measured from the left, right, or the panel can be in the middle. Just as long as there is 30" clear in front of the panel.

Thanks that sounds much better. A book by Sunset stated a panel needed 30" on either side as well as 36" in front of the panel and that sounded pointless. In fact it would've really made the area useless to me negating the need for a subpanel.

Think about most panels are on side walls in closets, and they are seldom more than 36"-48" deep to begin with, so having a 30" clearance on sides would be impractical.

Just to be clear you still need 36" deep of working space. Think of it as a box that is 30" wide and 36" deep in front of the panel.

But of course that is an electrical closet not a storage closet.

Clearance

The door may be a part of the 30 in. space, as the space would not be affected when the door is closed. The work bench may not be in the space.
