Power Connection Options
Appropriate power cord accessory kit is determined by the voltage and the amperage of the
branch circuit, based on the unit amperage requirements (for example, electric heater size). The
unit ships without a power cord.
NNoottee:: Ensure the outlet matches the appropriate prong configuration on the plug. It should be
within reach of the service cord. All wiring, including installation of the receptacle, must be
in accordance with the NEC
™
and all local codes, ordinances and regulations. National
codes require the use of an arc fault or leakage current detection device on all 208/230V
power cords. For 265V units, if power cord accessory option is selected, then the cord is
only l8" long and must plug into the accessory electrical 265V sub-base.
All Units
IImmppoorrttaanntt:: Follow NEC and local electrical codes when installing electrical supply wiring. The
following is only shown as a sample.
Use recommended wire size (Table 1) and install a single-branch circuit. All units are designed to
operate off only one (1) single branch circuit.
NNoottee:: Only use copper conductors. Branch circuit wire is single circuit from main box. AWG wire
sizes are based on copper wire at a 140°F (60°C) temperature rating.
Table 1. Common Branch Circuit Wire Sizes
Nameplate Amps AWG Wire Size
7.0 to 12 14
12.1 to 16 12
16.1 to 24 10
Grounding
For safety and protection, the unit is grounded through the service cord plug or through separate
ground wire provided on hard wired units. Ensure that the branch circuit or general purpose
outlet is grounded.
