For a 125 VDV 1.6 W motor, is it necessary by NEC to consider inrush current in the calculation to size the conductor for the motor circuit?

 

1.6 watts will only use .0128 amps at 125 Volts DC. I can't remember the NEC saying anything about milliamp level circuits and I can't think of any reasonable size wire or circuit breaker that will not survive that load.

 

Sorry #12 (or #32 incognito?). I failed to type the k in front of W. The motor is 1.6 kW.

 

Section 430 of the NEC is a very long chapter. I found 2 places that say to use the locked rotor current for ampacity and several tables calling for a percentage based on use. Then there is table 430-152 about dc motors less than 50 hp:

non-time delay fuse = 150% of FLA
dual element fuse = 150% of FLA
instantaneous trip breaker = 250% of FLA
inverse time breaker = 150% of FLA

So much writing that you have to declare pretty much everything about what it is and how you're going to use it.

 

Thanks fore your help. Have a good weekend.
