Circuit Breaker Sizing for Motors

[aelec84]

Hello,

I need clarification on breaker sizing for small motors less than 1/6 HP. My understanding is circuit breaker in panelboard can act as disconnecting means. The mechanical unit data states 5 Amp MOP breaker. Trying to figure out per code sections what is the max. size breaker allowed for this installation.
Thank you.

While the code would permit a 15 amp breaker, (10 amp in the 2023), if the instructions specifies "Maximum Overcurrent Protection" of 5 amps, that becomes a 110.3(B) code requirement.

Thank you for pointing to the 110.3(B) requirement.
However which section would permit a 10A breaker? FYI this is a 120V unit. I am using 2023 NEC.

Likely it's GFSC protection and covered by 430.52

- This is only true if the equipment being served is located "within sight" of said circuit breaker

Where would you or how would you go about finding a 5amp Circuit Breaker ?
