Electrical Installation: Field Power Wiring
In compliance with the National Electrical Code, an
electrically 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.

Notes:
1. All wire sizes assume separate conduit for each set of parallel conductors.
2. All wire sizes based on NEC Table 310-16 for 75°C THW wire (copper).
Canadian electrical code wire ampacities may vary.
3. All wire sizes assume no voltage drop for short power leads.
