Notes
Maximum circuit ampacity (MCA) =
1.25 x (FLA motor 1 + FLA motor 2 + FLA electric heat)
Maximum overcurrent protection (MOP) =
(2.25 x FLA motor 1) + FLA motor 2 + FLA electric heat
If the calculated MOP is within 10% of the next smaller available
fuse size, that fuse size shall be used. If not, the next larger fuse
size above the calulated MOP must be used.
If the selected MOP is smaller than the MCA, the selected MOP
must be increased to the next larger available fuse size above the
MCA.
If the MOP is less than 15, it shall be rounded up to 15 amps. This
is the minimum fuse or circuit breaker permitted by code.
