If wire is applied at ambient greater than 30
_
C, consult table 310---16 of the NEC (NFPA 70). The ampacity of non---metallic---sheathed cable (NM), trade
name ROMEX, shall be that of 60
_
C conditions, per the NEC (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 (NFPA 70).

Length shown is as measured one way along wire path between unit and service panel for voltage drop not to exceed 2%.
** Time---Delay fuse.

--- 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 2007 requirements of ASHRAE Standards 90.1
