I have LED fixtures rated 277v with a controller that uses 0-10vdc to perform dimming function.
I have ordered dimmer switches that are rated to switch 277 vac and also have a 0-10vdc / 200ma max output for dimming.
My concern is that the switch does not appear to meet NEC 725.121 (A) requirements thus it will require class 1 wiring methods for the 0-10v, not a problem just my peers diagree and say class 2 is exceptable.
cooper electric sales and technical support are of no help
Can I get some help here?
