HCS Installation and Operation Manual
Wiring instructions (hardwired)
Route the HCS conduit to a nearby junction box. Use the included ½" trade size watertight conduit fitting and sealing
washer to provide a moisture-resistant seal between the conduit fitting and the junction box. If necessary, drill a ⅞" diameter
hole to accommodate the conduit fitting. For outdoor installations, ensure the junction box is fully sealed using appropriate
electrical grade silicone sealant.
Before connecting the service conductors, please carefully read the section of this manual titled Installation - Service
connections. If unsure of the type of power provided at the service panel, please consult with the local utility or call a
Service Representative for assistance.
The three supplied HCS-40 service conductors use stranded 10 AWG 90°C copper wire.
The three supplied HCS-50, HCS-60, and HCS-80 service conductors use stranded 8 AWG, 90°C copper wire.
The insulation of each conductor is color-coded for standard 240 VAC installation:
