Electrical room - ground bar clearance

[anbm]

Is the clearance required for ground bar inside electrical room rather than the ground bar needs to be accessible?

What do you mean by clearance, are you really referring to accessibility?

3' clearance at front, no obstacles.

The ground bar is not included in the list of electrical equipment that is likely to be worked on while energized. It is never energized. So there are no requirements for working clearance in front of the ground bar.

It is never energized.

Under normal operating conditions. All bets are off if there is an open grounded conductor at the service.
