Electrical data
* Permissible limits of the voltage range at which unit will operate satisfactorily. Operation outside these limits may result in unit failure.
† 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 nonmetallic-sheathed cable (NM), trade name ROMEX, shall be that of 60°C (140°F) conductors, per the NEC (ANSI/NFPA 70)
Article 336-26. If other than uncoated (non-plated), 60 or 75°C (140 or 167°F) insulation, copper wire (solid wire for 10 AWG and 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 the unit and service panel for a voltage drop not to exceed 2%.
** Time-delay fuse.
