Refer to the unit rating plate and/or Table 2 for wire
sizing information and maximum fuse or circuit breaker
size. Each unit is marked with a “Minimum Circuit
Ampacity”. This means that the field wiring used must
be sized to carry that amount of current. Depending on
the installed KW of electric heat, there may be two field
power circuits required. If this is the case, the unit
serial plate will so indicate. All models are suitable
only for connection with copper wire. Each unit and/or
wiring diagram will be marked
“Use Copper Conductors Only”. These instructions
must be
adhered to. Refer to the National Electrical
Code (NEC) for complete current carrying capacity data
on the various insulation grades of wiring material. All
wiring must conform to NEC and all local codes.
The electrical data lists fuse and wire sizes (75°C
copper) for all models, including the most commonly
used heater sizes. Also shown are the number of field
power circuits required for the various models with
heaters.
