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). This unit ships without a
power cord (or hard wire kit). An accessory power cord
must be ordered to connect the unit to the outlet.
NNootteess::
• 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 18"
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 2. 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.
Voltage Supply
Check voltage supply at outlet. For satisfactory results,
the voltage range must always be within the ranges
specified on the data information plate. Power cord
does not ship with the unit. The cord to order is
determined by the unit voltage and the desired electric
heat capacity.
Cord/Connected Units
The 250 Vac field supplied outlet must match the plug
for standard 208/230V units and be within reach of the
service cord.
NNoottee:: Do NOT use 30 amp cord with sizes 07 and 09
units.
