Control Wires
Control wires between the switch and the generator consist of:
 Utility voltage sensing wires N1 and N2,
 Operating control wires #23,and 15B or 194 and 0,
 And don't forget T1 120VAC for the Battery charger.
GenReady
 Connect N1 and N2 to the 15A 2 pole breaker provided in the top of the load center (switch).
 Connect wires 23 to Transfer, 15B or 194 to 12VDC+ and 0 to 12VDC - on the green block on the side
of the transfer switch operator.
 The transfer switch operator requires a 5A fuse (supplied) in the +12Vdc for operation.

It will be necessary to install the 5A fuse in the 12Vdc supply line before it leaves the generator.
 Wire T1 (battery charger) from the generator will go to the bottom right 15A Duplex Breaker (Not
Supplied) to be installed on the Generator-fed load circuit breakers.
 Control circuit wire must run in a separate conduit, unless the length is 30 feet or less.
 All control wires must be a minimum 300Vac rating and #14 AWG size. (Generac Control & Install
Cables are #18 AWG 600Vac rated)
 THHN wire is recommended. Do not use Thermostat wire.
RTSY/T/W, RTSR/P/C, RTSB, RTSI, RTJ
 The Control wires are routed to the Fuse block and connection block next to the Main Breaker.
 On the Fuse Block N1 and N2 (Utility) are the Yellow N1 and N2 sensing wires.
 T1 (Load) is for Blue T1 battery charger wire.
 On the small Block, White 23 Transfer is for the white 23 wire for transfer signal control.
 Red 194 +12VDC is for the Red 15B or 194 +12VDC for the transfer relay.
 Black 0 DC Common is for the black 0 wire common ground.
RTG – Prewired
 The Control Wires are prewired on the RTG Switches from the 30' whip.
require a 0 wire.
Circuit Breakers RTG-EZ Switch & RTSR/I Sub-Panel
Note: Some local codes may require splices to be in a separate junction box not in the main panel box.
 Turn off the main breaker on the distribution panel before running any wires into the panel box.
 Balance must be maintained when moving circuit locations from the main panel box to the emergency
load center.
 Circuit breaker positions alternate buss bars vertically.
 Circuits sharing a neutral wire should be either moved together or NOT moved.
 Circuits to be removed must be protected by the same size breaker. For example, 15A to 15A, 20A to
20A. (RTG is all #12 wire so you can swap out the breakers)
 In the main panel box, remove the black wire (hot) from the circuit breaker of the circuit to be
protected in the event of a power failure.
 Connect it to the matching lead from the circuit breaker in the load center of the transfer switch.
 All circuit wires in the transfer switch load center are color-coded and labeled for easy identification.
 Trace each black (hot) wire connected and remove the corresponding white wire from the neutral
block in the main panel (from the same Romex cable).
 Connect the white wire to the matching circuit number on the white (neutral) wire from the
emergency load center.
 Repeat this process for the remaining circuits to be transferred to the transfer switch load center.
 Use the same procedure for the RTSR/P/C Sub-Panel except it will not be prewired in the Sub-Panel.
Note: RTG switches do not
