I think i know answer but just checking with the smartest folks. If I size branch circuit conductors for a system with 4 continuous motors according to NEC430.24 i use the table based FLA with but there is no comment on the 125% for continuous duty. there is comment for sizing conductors for single motor.
Take 125% of the FLC of the highest-rated motor.
Add the FLC of all other motors on the same phase.
Add 100% of any non-continuous non-motor loads and 125% of any continuous non-motor loads on the same feeder.
The sum of these values is the minimum ampacity your conductors must handle
I am thinking that I still need to use the 125% for all 4 motors and add the appropriate non motor loads.
thanks y'all!
