G 25 Operationwc_tx000137gb.fm 372.14 Ground ConnectionSee Graphic: wc_gr001684A ground connection (s) is located next to the terminal lugs. The unitmust have this ground lug connected to a good earthen ground forproper operating safety in compliance with NEC and local standards.2.15 Convenience ReceptaclesSee Graphic: wc_gr001684The generator is equipped with one 120V/240V twist lock receptacle(m) rated at 30A, and one 120V/240V twist lock receptacle (l) rated at50A. The two 120V duplex receptacles (n) are equipped with groundfault interrupts (GFI). Receptacles do not connect through the mainline circuit breaker. Each receptacle is protected by its own circuitbreaker (k) which is located directly above it. Power to the receptaclesis available any time the generator engine is running, even with themain line circuit breaker open.Note: For the G25, when the voltage selector switch is in the 480V/3Øposition, voltage at the duplex receptacles is 139V, and voltage at the30/50A receptacles is 139/240V. When the voltage selector switch isin the 208V/3Ø position, voltage at the 30/50A receptacles is 120/208V. When the voltage selector switch is in the 208V/3Ø position, thevoltage can be adjusted with the voltage adjustment rheostat (f) to240V/3Ø. The voltage at the duplex receptacles is 139V, and voltageat the 30/50A receptacles is 139/240V.2.16 Remote Run Terminal BlockSee Graphic: wc_gr001684The 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.2.17 Panel Door Interlock SwitchSee Graphic: wc_gr001684The 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.
