Scott beat me to it.
Commentary - Considering an air compressor is not required to be Listed,
the technical committee is putting requirements into the standard. Maybe
the air compressor should be Listed for Fire Protection use.
Thanks,

It may not be a skylight, but I don't see why you couldn't consider it a
"similar pocket" to a skylight.

A switch that looks like a light switch would be legit for a small motor.
If the compressor is on a dedicated 20A circuit it would need to be a 20A
rated switch. You wouldn't be able to tell a 20A from a 15A (common light
circuit rating) without looking at the rating. If it's a 20A/230V
compressor
I think you'd find that in the electrical code, but, and if my
memory serves me from many, many years ago, and if it hasn't changed in the
several iterations of NFPA 70 since the 1970s when I was an electrical
inspector any motor over 1/8th HP requires a disconnect within sight of
that motor or
Like the one for a light switch, there is breaker in the electrical panel with
a lock-out

You are required to have a disconnect switch. What kind of “On/Off” switch are
you seeing?

Made a inspection to one of my jobs today and found that the electrical
contractor installed a On/Off
switch to the air compressor which I know isn't allowed.
Where does it state in NFPA that this isn't allowd?
Thanks,
Mike

IMHO, a clerestory light well is not a skylight. It's a ceiling pocket, but
not a skylight.

I have a 12 x 36 x 58 tall pocket in they ceiling at a clerestory.
If this is consider a skylight per 13-8.5.7 (16ed) I would not have to
provide protection at the top of the pocket.
But if is a pocket per 13-8.6.7 and since its over 36" tall I'm going have
to provide protection at the
