All Units
The minimum circuit ampacity (wire sizing amps) is shown on
the unit nameplate. Refer to
number of power wires.
Copper wire is required for all conductors. Size wires in
accordance with the ampacity tables in Article 310 of the
National Electrical Code. If long wires are required, it may
be necessary to increase the wire size to prevent excessive
voltage drop. Size wires for a maximum of 3% voltage drop.
Supply voltage must not vary by more than 10% of nameplate.
Phase voltage imbalance must not exceed 2%. (Calculate
the average voltage of the three legs. The leg with voltage
deviating the farthest from the average value must not be more
than 2% away.) Contact the local power company for correction
of improper voltage or phase imbalance.
A ground lug is provided in the control panel for each
disconnect or power block. Size grounding conductor in
accordance with Table 250-95 of the National Electrical Code.
In compliance with the National Electrical
isolated 115V circuit is provided in the unit to supply the factory
mounted service receptacle outlet and optional unit lights.
This circuit is powered by a field connected 15A, 115V power
supply. Leads are brought into the RFS and RPS units through
a 7/8" knockout in the bottom of the main control panel, near
the power wire entry point.
