The wiring of the unit must be suitable for the MCA
calculated above, and the Maximum Overcurrent Pro-
tection (MOCP) device must be selected to meet the
calculated MOCP.
If the overcurrent protective device for the combina-
tion load is equal to or less than 60 amps, a single dis-
connect may be used for BOTH the main unit and the
62AQ provided that the wire ampacity supplying the
62AQ is sized for a minimum of 33% larger than the
overcurrent protection device value (i.e., 60 amps
x 0.33 = 20 amps), no further subfusing would be
required.

If the overcurrent protection device is greater than
60 amps and the old overcurrent protection device
was less than 60 amps, a FUSED disconnect no
greater than 60 amps must be provided for the main
unit and a SEPARATE FUSED disconnect must be
provided for the 62AQ unit.

If the old overcurrent protection device is greater than
60 amps, a disconnect is required for the MAIN UNIT
as well as a FUSED DISCONNECT for the 62AQ
unit.
