**Main power wire from electrical panel to outdoor unit. AWG based on 240VAC Single Phase, 100 ft. distance 1-way, max. 5% allowable voltage drop.
Notes: 1) System must be on a single dedicated circuit.
2) Main power is supplied to the outdoor unit.
3) Use table above to size over current protection.
4) Follow all local building codes and NEC (National Electrical Code) regulations.
Interconnecting Cable: Recommended cable - 14/4 AWG stranded bare copper conductors THHN 600V unshielded wire
Note: Use shield cable if installation is in close proximity of RF and EMI transmitting devices.
