Compressor Motor
Notes : 1. Electrical data is for each individual motor. 2. Maximum Overcurrent Protection device permitted by N.E.C. 440-22 (1993) is 225% of the largest compressor motor RLA plus the remaining motor RLA and FLA values. 3. Minimum circuit ampacity is 125% of the largest compressor motor RLA plus the remaining motor RLA and FLA values. 4. Recommended dual element fuse size is 150% of the lar
