The unitmust have this ground lug connected to a good earthen ground forproper operating safety in compliance with NEC and local standards.3.15 Convenience ReceptaclesSee Graphic: wc_gr002611The generator is equipped with two 120V/240V twist lock receptacles(l) rated at 50A, and one 120V/240V twist lock receptacles (m) ratedat 30A. The two 120V duplex receptacles (n) are equipped withground fault interrupts (GFI). Receptacles do not connect through themain line circuit breaker. Each receptacle is protected by its own circuitbreaker (h, j, k) which is located directly above it. Power to thereceptacles is available any time the generator engine is running, evenwith the main line circuit breaker open.Note: When the voltage selector switch is in the 480 V / 3Ø position,voltage at the duplex receptacles is 139 V, and voltage at the 30/50 Areceptacles is 139/240 V. When the voltage selector switch is in the208 V / 3Ø position, voltage at the 30/50 A receptacles is 120/208 V.When the voltage selector switch is in the 208 V / 3Ø position, thevoltage can be adjusted with the voltage adjustment rheostat (f) to 240V / 3Ø. The voltage at the duplex receptacles is 139 V, and voltage atthe 30/50 A receptacles is 139/240 V.3.16 Remote Run Terminal BlockSee Graphic: wc_gr002611The remote run terminal block (o) is located just to the right of the 120Vduplex receptacles. It provides connection points for installation of aremote start switch. When it is connected to a transfer switch, it allowsthe generator to be used as a standby power supply.3.17 Panel Door Interlock SwitchSee Graphic: wc_gr002611The customer connection lugs panel access door is equipped with aninterlock switch (q). When the door is opened this switch automaticallytrips the main circuit breaker. Voltage to the receptacles will not be cut.
