Exterior Access to Electrical Room

[liarchitect]

Does the electrical room for a 1 story commercial building need to have access from the interior or can i have only exterior access?

Thank you in advance

Looking in Article 110 of the NEC, it looks like either is permitted. You would have to use the amperage and voltage provision along with the door location.

I believe either is fine. Typically, I will design with exterior access only. In a recent bank building, I had originally designed interior access only which we later changed to exterior because the local PUD required keys for access and we weren't too keen on handing out keys to the bank.

So, Mark.. who has access to the electrical equipment.. just the FD?

My guess would be the utility co. would have a key if the meter is in there(Editops, Mark Randall already said the PUC has a key...) and the FD would probably have access via Knox box.
