Section 4: Inverter/Charger Installation
gauge number indicates a smaller wire diameter (for example: a 2 AWG cable is smaller than a 00
AWG cable). Under the MCM standard, a larger number indicates a larger cable (example: a 350 MCM cable is larger than a 250 MCM cable). Wire size is usually marked on the cables for sizes this large.
DC Disconnect and
Batteries Every Prosine inverter/charger system requires a
Generator When a generator is included as a secondary AC power source, a manual or automatic AC source selector switch must be installed ahead of the circuit breaker in the line leading to the inverter/charger. In marine and RV applications, the AC cabling from the generator to the circuit breaker must be composed of stranded cable. Both the Line (Hot) conductor and the Neutral conductor must be protected by circuit breakers. If the generator is the only AC shorepower source, no source selector switch is needed.
Ground Fault Circuit Interrupters (GFCIs) A GFCI is a device that
Installations in marine and recreational vehicles may require GFCI protection of branch circuits connected to the AC output of the inverter/charger. In addition, electrical codes require GFCI protection of certain receptacles in residential installations.
While the true sine wave output of the Prosine inverter/charger is equivalent to the waveform provided by utilities, compliance with UL standards requires that Xantrex test and recommend specific GFCIs. Xantrex has tested the
