This total is the FLA. MCA (minimum circuit amps/wire size) Calculation: Take the FLA of the highest load (typically the pump motor) and multiply it by 1.25, then add all the remaining FLA s without the multiplier. This number is your MCA. MFS (maximum fuse size) Calculation: Take your FLA of the highest load and multiply it by 2.25, then add all the remaining FLA s without the multiplier. Take this number and round down to the next lowest standard fuse size. Electrical Data - Glycol Pump Packages Example: Pump motor 8.2 amps per motor Dry cooler Fans X 4 amps per fan Control transformer 0.5 amps 8.2 + 0.5 16.7 FLA (8.2) X 1.25 = 10.25 + 0.5 18.75 MCA (8.2) X 2.25 = 18.45 + 0.5 26.95 MFS NEC standard fuse sizes: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 100, 125, 150, 175 so the final MFS in this case would be 25 amps. 3-7
