NOTES:
1. Wire sizes, lengths, fuse sizes and dual element fuse sizes shown are for the branch circuit between the disconnect
switch and the unit.
2. The branch circuit wire sizes and the corresponding maximum wire lengths tabulated will result in a 1% voltage drop
at the nameplate full load amperage. The wire size listed and the maximum fuse sizes are in accordance with the
National Electric Code.
3. Dual element fuses can be sized much closer to the actual running current than one-time link type fuses because of
the built-in lag. Thus, dual element fuses give additional motor protection against both single phasing and locked
rotor failure, should starter contacts fuse. Use dual element fuses for compressor protection on all installations.
With properly selected fused disconnect switches, fuse reducers may be required.
4. Units having 3 phase fan motors require a separate disconnect switch and fuses or dual element fuses for the fan
motor circuit as well as a separate disconnect switch and dual element fuse for each compressor circuit.
