240.6 Standard Ampere Ratings 37 (B) Adjustable‐Trip Circuit Breakers The rating of adjustable trip circuit breakers having external means for adjusting the current setting (long‐time pickup setting), not meeting the requirements of 240.6(C), shall be the maximum setting possible. NEC 240.6 (A) lists standard fuse and circuit breaker sizes. Because there are no standard sizes between 20- and 25-amp ratings, a 20-amp fuse or circuit breaker is the correct size for the single overcurrent protection device. Referring to NEC Table 240.6 (A), we will be able to determine the next standard circuit breaker rating available.

Therefore: Use 300amp 3-pole circuit breaker (per NEC 240.6). 240.6 Standard Ampere Ratings 37 (B) Adjustable‐Trip Circuit Breakers The rating of adjustable trip circuit breakers having external means for adjusting the current setting (long‐time pickup setting), not meeting the requirements of 240.6(C), shall be the maximum setting possible.

All other motors other than ones with a nameplate of 1.15 or more or with a nameplate temperature rise of 40°C shall have the overload device sized at no more than 115% of the motor’s FLA. The movement to reduce arc energy and protect workers servicing energized equipment is on. The 2014 NEC began raising awareness by the changes made in 240.87 pertaining to large frame circuit breakers.
