* Permissible limits of the voltage range at which the unit operates satisfactorily .
# Unit ampacity = 125 percent of largest operating component’s full load amps plus 100 percent of all other potential operating components’ (EAC, humidifier,
etc.) full l oad amps.
{ Time---delay type is recommended.
} Length shown is as measured one way along wire path between furnace and service panel for maximum 2 percent voltage drop.

Low Amp K it ( NAHA00101PC all o ws select furna ces to be installed with a 15 Amp Breaker and 14 AWG wire within th e listed wire len gth. Affected data
shown as Default Value/Value with Lower Amp Kit.
ELECTRICAL SHOCK AND FIRE HAZARD
Failure to follow this warning could result in personal
injury, death, or property damage.
The cabinet MUST have an uninterrupted or unbroken
ground according to current edition of NEC NFPA 70 or
local codes to minimize personal injury if an electrical fault
should occur. In Canada, refer to the current edition of
Canadian Electrical Code CSA C22.1. This may consist of
electrical wire, conduit approved for electrical ground or a
listed, grounded power cord (where permitted by local
code) when installed in accordance with existing electrical
codes. Refer to the power cord manufacturer’s ratings for
proper wire gauge. Do not use gas piping as an electrical
ground.

WARNING
FIRE HAZARD
Failure to follo w this warning could result in personal
injury, death, or property damage.
Do not connect aluminum wire between disconnect
switch and furnace. Use only copper wire. See Fig. 33.

WARNING
A190279
Fig. 33 -- Field--Supplied External Electrical Box on Furnace
Casing
115-- V Wiring
Furnace must have a 115-v power supply properly connected and
grounded.
NOTE: Proper polarity must be maintained for 115-v wiring. If
polarity is incorrect, control LED status indicator light will flash
rapidly (Status Code 10) and furnace will NOT operate.
Verify that the voltage, frequency, and phase correspond to that
specified on unit rating plate. Also, check to be sure that service
provided by utility is suf ficient to handle load imposed by this
equipment. Refer to rating plate or Table 11 for equipment
electrical specifications.
USA Installations: Make all electrical connections in accordance
with the current edition of the National Electrical Code (NEC)
NFPA 70 and any local codes or ordinances that might apply .
Canada Installations: Make all electrical connections in
accordance with the current edition of the Canadian Electrical
Code CSA C22.1 and any local codes or ordinances that might
apply.
Use a separate, fused branch electrical circuit with a properly sized
fuse or circuit breaker for this furnace. See Table 11 for wire size
and fuse specifications. A readily accessible means of electrical
disconnect must be located within sight of the furnace.
J-- Box Installation
FIRE OR ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury, death, or property damage.
High voltage field connections must be located in J--Box
with furnace, or in field supplied external disconnect
mounted to furnace.
If field--supplied manual disconnect switch is to be mounted
on furnace casing side, select a location where a drill or
fastener cannot damage electrical or gas components.
!
WARNING
The J--Box must be used when field line voltage electrical
connections are made to the furnace wiring harness inside the
furnace casing. The J--Box cover is not required if a field --supplied
external electrical box is attached to the outside of the furnace
casing. The field ground wire and furnace main ground wire are
grounded when the J--Box bracket is attached to the furnace and
the field ground wire and factory ground wire are secured to the
bracket grounding screw. If the J--Box cover is not used, the field
and factory spliced connections must be located inside the external
electrical box. Do not leave splice connections unprotected inside
the furnace.
