occupancy sensor

[Hendrix]

Are sensors allowed to be the only way to turn a light on in a commercial bathroom?

I don't see anything to the contrary. I wired several schools years back, & that's all we installed for lighting control then.

agreed in dwellings it has to have a manual override switch on it but in other than dwelling it doesn't

agreed in dwellings it has to have a manual override switch on it . . .

Where would I find that in the NEC? :?

The International Energy Code which is adopted in much of the country in Section 505.2.1 requires a manual control. IMO a manual override would suffice.

In many jurisdictions (as is the case in Utah) the IRC rather than the NEC will govern the electrical installation in a single family home. Where this is the case, Section E3903.2 will require the manual override in habitable spaces (but not in bathrooms).

A good chance to remide everyone that there's more to life than just the NEC.

210.70(A) Dwelling Units.
(1) Habitable Rooms. At least one wall switch?controlled
lighting outlet shall be installed in every habitable room
and bathroom.
Exception No. 1: In other than kitchens and bathrooms,
one or more receptacles controlled by a wall switch shall
be permitted in lieu of lighting outlets.
Exception No. 2: Lighting outlets shall be permitted to be
controlled by occupancy sensors that are (1) in addition to
wall switches or (2) located at a customary wall switch
location and equipped with a manual override that will
allow the sensor to function as a wall switch.

That does not prohibit us from installing a second light that is controlled only by an occupancy sensor. I can see some advantage in having a ceiling light (for general illumination) controlled only by an occupancy sensor, and a vanity light controlled by a manual switch.

Your right, I was going on the assumption we were talking about a single light based on the OP.
But yes I agree if you install a separate light that complies with the rule I posted you can also install one controlled by the occupancy sensor only. Super job Charlie!

As I said, this is not a dwelling, so it dosen't need a switch:?

The NEC does not require it to have a switch. The owner may want one anyway, but that is between you and the owner.
