{
If wire is applied at ambient greater than 30° C, consult table 310---16 of the NEC (ANSI/NFPA 70). The ampacity of non---metallic---sheathed cable (NM),
trade name ROMEX, shall be that of 60° C conditions, per the NEC (ANSI/NFPA 70) Article 336---26. If other than uncoated (no---plated), 60 or 75° C
insulation, copper wire (solid wire for 10 AWG or smaller, stranded wire for larger than 10 AWG) is used, consult applicable tables of the NEC (ANSI/NFPA
70).

Length shown is as measured 1 way along wire path between unit and service panel for voltage drop not to exceed 2%.
** Time---Delay fuse.
FLA
--- Full Load Amps
LRA --- Locked Rotor Amps
MCA --- Minimum Circuit Amps
RLA --- Rated Load Amps
NOTE : Control circuit is 24---V on all units and requires external power source. Copper wire must be used from service disconnect to unit.
All motors/compressors contain internal overload protection.
Complies with 2001 requirements of ASHRAE Standards 90.1
