Symbols:
MCA: Min. Circuit Amps.
MFA: Max. Fuse Amps..
FLA: Full Load Amps.
Kw: Rate Motor Output
Notes:
5. Voltage range should not over the value of above table.
6. Maximum allowable voltage variation between phase is 2%
7. Selection wire size based on the larger value of MCA.
8. MCA/MFA
MCA = 1.25 × FLA
MFA ≤ 4 × FLA
(Next lower standard fuse rating min. 15A)
5. Instead of fuse, circuit breaker is also acceptable.
