I'm trying to size branch circuit OCPD and conductors for an elevator motor. The only data that I have for the motor is 16 HP at 30.6 RPM, and the utility voltage 208/3 phase.
For sizing the OCPD I need motor HP so my first thought what exactly is this info "16 HP at 30.6 RPM" even used for?
How do I get the HP to use for sizing the OCPD?
Does 30.6 RPM suggest a multi speed or low speed motor?
