Reliance Installation and Operating InstructionsKey Components of the Reliance Transfer SwitchCircuit breakersHandle tieCircuit selector switchesWatt meters(select models only)Wiring CompartmentCoverPower Inlet(not installed onindoor models).Figure 1Circuit breakers. Each transfer switch circuit has a 15- or 20-amp push-to-reset circuitbreaker that protects the branch circuit when the circuit selector is in the GEN position. Inthe LINE position, each branch circuit is protected by the breaker in the load center.Circuit selector switches. These switches allow you to select either GEN (generator) orLINE (utility) as the power source for the branch circuits that have been wired through thetransfer switch. The OFF position is generally not used, as a switch in the OFF positionremoves that branch circuit from both utility and generator power.Handle ties. Handle ties are used for 240-volt circuits. They may be removed for 120-voltcircuits. See page 6 for instructions on removing and adding handle ties.Power inlet (cord-connected models only). The power cord from the generator is pluggedinto this inlet. This is supplied separately for indoor models to encourage the use of aremote connection outdoors reducing the likelihood of running the generator indoors whichis extremely dangerous (see page 7 for installation instructions). If this indoor model isinstalled outdoors, make sure it is protected from the outdoor elements.Power inlet filler plate. Models without the power inlet installed have a filler platecovering the hole in the wiring compartment cover (models shown on cover). This can bereplaced with a power inlet (see Power inlet above).Wiring Compartment Cover. All models include a wiring compartment that can be usedto hard-wire the unit to a remote power inlet box.Watt meters (select models only). These meters indicate the total load, in watts, on eachside of the generator when the generator is supplying power as follows:The left meter measures the load onThe right meter measures the load onA, B and C6-circuitD, E and F6-circuitA, B, C, and D8-circuitE, F, G and H8-circuitA, B, C, D and E10-circuitF, G, H, I and J10-circuitNote: The watt meters will register only if power is being used from the generator.2

Installation InstructionsPreparing for InstallationYou will need the following items:Electric drillScrewdriverWire cutters/stripperHammerFour anchors and screws4, 6, 8 or 10 yellow wire connectors (depending on the model)4 red wire connectors for the 20A and 30A hard-wire models4 blue wire connectors for the 50A hard-wire modelsThe following five steps generally apply to all transfer switch installations. For flushmounted units (model number begins with the letter "F"), please see the supplementalinstallation instructions packaged with each unit, as they will supercede some of theinstructions shown here. For outdoor units (model number begins with the letter "R"),connect the wires from the unit to the main panel per these installation instructions.Please note the special conduit for the outdoor unit is included but not installed on the unit.Install the conduit supplied using acceptable practices for a raintight application.The transfer switch may be installed on either side of the load center.1. Turn off the main circuit breaker in the load center to ensure yoursafety.Danger: All current-carrying parts on the LINE side of the mainare still live2. Remove the cover of the load center.3. Locate and remove a knockout (ko)in the bottom of the load center(Figure 2). Use a 1/2" ko for 4-circuitmodels, a 3/4" ko for 6-circuitmodels, and a l" ko for 8-to 10-circuitmodels.4. Insert the wires extending from theend of the flexible conduit throughthe ko. Attach the conduit connectorsecurely with the locknut provided.5. Anchor the transfer switch to the wallusing the external feet. Do notattempt to bend the flexible conduitbeyond its structural capabilities.3Figure 2

Wiring the Reliance Transfer Switch to the Load CenterDetermine which circuits will be used during an emergency. See the residential wattagerequirement chart on the inside front cover of this manual. If a selected circuit is part of amulti-wire branch circuit, ensure the other branch circuit that shares the neutral is alsoconnected to the transfer switch. The two circuits must be connected to opposing legs(phases) of the generator power and a handle tie must be installed on the switch handlesso that both legs are transferred at the same time.Warning: Failure to properly install a multi-wire branch circuit could result inoverloading the neutral wire.The maximum number of circuits available and those that can be used for multi-wirebranch circuits depends on the model of the transfer switch as follows:ModelMaxAvailable for multi-wire branch circuits15114A, 30114A4 None31404A, B or C, 20504B, 30504B4 Circuits B and C.All 6-Circuit Models6 Circuits C and D only on indoor models.Any two adjacent circuits on outdoor models(models with an "R" prefix).All 8-Circuit Models8 Any two adjacent circuits.All 10-Circuit Models10 Any two adjacent circuits.Balancing the LoadTo maximize the efficiency of your generator,divide appliance circuits and others requiringhigher wattage between the left and right sideof the transfer switch so that a usage balanceis achieved.For example, on a 6-circuit transfer switch,consider wiring the refrigerator to Switch Aand the furnace to Switch D (Figure 3).Figure 3Installing 120-volt CircuitsWarning: Transfer switch circuits with 20 amp breakers (the ones with the redcaps) must be installed on only those branch circuits with 20 amp branch circuitbreakers. Transfer switch circuits with 15 amp breakers can be installed on 15 or20 amp branch circuits. Do not install any transfer switch circuit on branchcircuits greater than 20 amps.Wire the most critical circuits first, starting with Switch A on the transfer switch. Let'sassume that Switch A will be designated to supply power to the refrigerator.4

1. Turn off the refrigerator circuit breaker. Loosen the screw that secures the wire to thecircuit breaker. Disconnect the wire from the circuit breaker.2. On the transfer switch, find the black and red wires marked A.3. Feed the red wire to the selected breaker, in this case the refrigerator breaker.4. Cut the red wire A to a convenient length. Strip approximately 5/8" from the end of thewire. Connect the red wire to the refrigerator circuit breaker and retighten the screw.5. Cut the black wire A to a convenient length for aligning with the wire removed from therefrigerator circuit breaker in step 1. Strip approximately 5/8" from the end of the wire.6. Insert both wires (the wire removed from the circuit breaker in step 1 and the blackwire) into a yellow wire connector. Twist the connector tightly and push the wires backinto the wiring compartment of the load center.This completes the installation of the transfer switch for your refrigerator.Repeat steps 1-6 for each of the remaining considering the following: See the following section for 240-volt circuits and the removal of handle ties if240-volt circuits are not required. Remember to "balance the load"—dividing the appliances requiring higherwattage between the left and right sides of the transfer switch. If you are installing model 15114A or 30114A, follow the same steps for B, C andD circuits, and proceed to the instructions for completing the installation on page8.5

Installing 240-volt CircuitsOn certain models, two adjacent circuit selector switches may be used for 240-voltoperation. A handle tie is used to connect the two circuit selector switches for the followingcircuits:Models 15114A, 30114ANone (these are for 120-volt use only)Models 31404A, B or C, 20504B, 30504BCircuits B and C.All 6-Circuit ModelsCircuits C and D only on indoor and flushmodels. Any two adjacent circuits on outdoormodels (Models with an "R" prefix)*.All 8-Circuit ModelsAny two adjacent circuits*All 10-Circuit ModelsAny two adjacent circuits**Note: Circuits used for multi-wire branch circuits are not available for 240-voltcircuitsRemoving handle ties. If there are no 240-volt or multi-wire circuits in the transfer switchinstallation, handle-ties on the switches are not needed. To remove a handle tie, place thehandle-tied switch in the GEN position. Loosen the two screws and remove the handle tie.Adding handle ties. If additional ties are needed to accommodate additional 240-voltor multi-wire circuits, they can be added to adjacent pairs of switches according to thetable above.Warning: Transfer switch circuits with 20 amp breakers (the ones with the redcaps) must be installed on only those branch circuits with 20 amp branch circuitbreakers. Transfer switch circuits with 15 amp breakers can be installed on 15or 20 amp branch circuits. Do not install any transfer switch circuit onbranch circuits greater than 20 amps.Installing 240-volt circuit(s)1. Locate the two red and two black wires for the circuits with the handle tie.2. Turn off the double-pole breaker in the load center.3. Loosen the screws that secure each wire to each circuit breaker. Disconnect the wiresfrom the circuit breakers.4. Feed the two red wires from the handle-tied switch(es) to the double-pole circuitbreaker.5. Cut the red wires to a convenient length. Strip 5/8" from the end of each wire. Connectthe two red wires to the double-pole circuit breaker.6. Cut the black wires to a length convenient for aligning with wires removed from thecircuit breaker. Strip 5/8" from the end of each wire.7. Insert one wire removed from the circuit breaker and one black wire into a yellow wireconnector. Twist to tighten and push the wires back into the wiring compartment of theload center. Do the same for the other wire removed from the circuit breaker and theother black wire from the transfer switch.Repeat steps 1-7 for the other double-pole circuits (8- and 10-circuit models only).For Indoor Surface Mount Models (those with no power inlet) or to hard-wire cordconnected Models (those with a suffix "A" in the Model number), continue to the nextsection entitled "Hard-wire Installation" to complete the installation.For all other models, skip to "Completing the installation" on page 8.6

Hard-wire Installation"Hard-wire" installation to a power inlet box located remotely from the transfer switch (Figure5) requires additional steps to complete the installation. The wire connections to the wiresfrom the power inlet boxare made in the wiringcompartmentoftheFigur e 5transfer switch. Accessthe wiring compartmentby removing the wiringcompartment cover (SeeFigure 1). This done byremoving the two screwslocated at the bottom ofthe front of the transferswitch.Replace thecover when installation iscomplete.Watt Meters.SomeModels are supplied with watt meters to measure the generator output. When connectingthe transfer switch to either a power inlet or power inlet box, run the black wire lead goingto the inlet through the hole in the current transformer (the small black doughnut-shapeddevice) attached to the left hand meter before connecting it to the power inlet or the wiresfrom the power inlet box. Run the red wire lead through the hole in the current transformerattached to the right hand meter before connecting it to the power inlet or the wires fromthe power inlet box. No direct connection to the meter is necessary for the meters tofunction as describe on the bottom of page 2.Hard-wire Models. All of these Models have leads in the transfer switch wiring compartmentthat need to be connected to the incoming wires from the remote power inlet box. See WattMeters above for Models ending with a suffix "C". Connect the wire leads in the transferswitch to the remote power inlet box usin
