Notes: Fuses and circuit breakers shown are for short-circuit ground fault protection only. This data applies to Normal Service applications of switches, starters or breakers shown. Do not use for Heavy Service applications, as defined in the latest Catalog Digest. Data is based on information available at time of publication and is subject to change. See actual installed equipment and Section 110-14C for termination requirements. Fuse sizes and circuit breaker trip amperes are approximate selections suitable for most installations. Thermal unit selectors are not based on NEC currents (see NEC 430-6) but are selected from average full load currents. Thermal units can be more accurately selected using table furnished with starter and full load current marked on the motor name plate.
