NGW WRAPPER
Electrical Recommendations
NGW Electrical Overview:
• The NGW needs a 220V 20A, single phase with neutral, dedicated circuit.
(Dedicated circuit means that the wires coming from the circuit breaker box only go to the wrapper)
• The NGW requires a neutral connection. Neutral must be hooked to earth ground in the install site circuit breaker box
(or however the local electrical codes call out)
• If using ceiling drops, ensure they are long enough to meet line cord length from NGW Wrapper.
• If replacing an existing competitor wrapper:
− Make sure the circuit is 1 phase 220V with a neutral and earth ground
− Ensure the dedicated circuit is 20A with at least 12AWG line
• The NGW does not ship with a power cord. The power cord is a 4 conductor 12 AWG and is water resistant.
DO NOT hook the NGW’s neutral to earth ground. THIS IS A SAFTEY REQUIREMENT.
Earth ground must not conduct any current during normal operation.
Electrical Connections in Field Wiring Box:
• RED - L1
• BLACK - L2
• WHITE – Neutral
• GREEN – Earth Ground
Male and Female Plugs:
CHECK WITH LOCAL ELECTRICAL CODES.
• Using the plugs may not be required, but are a good idea
