NOTES:
1. "Recommended Fuse Size" are selected at approximately 150% of the largest compressor RLA, plus 100% of all other
loads in the circuit.
2. "Maximum Fuse Sizes" are selected at approximately 225% of the largest compressor RLA, plus 100% of all other loads
in the circuit.
3. Supplemental overloads are used in conjunction with standard inherent overload protection. The supplemental overloads:
• Reduce wire sizing amps
• Add additional protection
• Lower compressor amperage
