* Permissible limits of the voltage range at which the unit will operate satisfactorily
{ If wire is applied at ambient greater than 30˚ C(86˚ F), 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 (140˚ F) conditions, per the NEC (ANSI/NFPA 70) Article 336---26. If other than uncoated (no---plated), 60
or 75˚ C (140 or 167˚ 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%.
