I wouldn't sweat it too much being brick, but I can also see that it would be pretty easy to shut off that breaker and move a wire out the way to install a KO seal as well.

It does not look to me like that breaker shuts off that wire. 50/50 chance based on what can be definitively seen in the picture, but knowing that the offset nipple likely leads to a meter base, it probably would require pulling the meter which may require meeting with the utility.

What panelboard? :huh:

.


Panelboard. A single panel or group of panel units designed
for assembly in the form of a single panel, including
buses and automatic overcurrent devices, and equipped
with or without switches for the control of light, heat, or
power circuits; designed to be placed in a cabinet or cutout
box placed in or against a wall, partition, or other support;
and accessible only from the front.

...
But putting that aside, if this is not a panelboard what NEC sections apply to it?
Article 408, but sections regarding switchgear. 408.2 specifies additional compliance with Articles 240, 250, 312, 404, and other articles that apply.

:D

I'd seal this one, if only in the vain hope the next man who pulls the deadfront doest rip a wasp nest in half in the process.
Same here, I even stick bolts in unused mounting holes as that is the only place they can get in sometimes and you still run into an occasional enclosure with a swarming surprise waiting for you when you open it.

It appears dkidd takes exception to my view that the equipment in the opening post is a panelboard.
I have to agree with him. I believe it is listed as an SUSE enclosed circuit breaker.

Article 408 still applies because it is used as switchgear.
