Lighting Contactor's

[brian@sutherland]

I am specifying ASCO 917 contactors. Can I mix 120V and 277V lighting on the same contactor? As I understand the contacts are rated appropriately.

Yes that is permited. You will have to comply with 210.5.

Thanks Don. I realized that 300.3(C)(1) is applicable.
