INSTRUCTIONS FOR TRANSFER SWITCHES
Reliance Controls ®
Manual Transfer Switches
and Operating instructions
Transfer Switches and Transfer Panels should be installed by a qualified
electrician familiar with residential wiring and electrical codes. Manufactures
accepts no responsibility for accidents caused by incorrect installation.
Since some states require that the installation be compliant with all
applicable laws and electrical codes, it is best to check with a local
electrician in your area. Estimated installation time is 1-2 hours.
Always thoroughly read the
instructions that are included with the switch you purchase. These instructions
are general and are not a substitute for reading the instructions and
using common sense. The installer is responsible for the installation
and must either know what they are doing or hire an electrician.
switches and panels are intended for single phase residential or light
commercial use. If you have any questions about your specific manual
transfer switch installation, you may call

For All Models, Tools
Needed for Installation:
of Manual Transfer Switches
for Circuit Selection
– These switches allow you to select
either utility (LINE) or generator (GEN) as the power source for the circuits
that have been wired through the transfer switch. The OFF position is not
generally used and a switch in this position will remove that circuit from
both the utility line and generator power.
Convenience Outlet (if
any) – Operates from
first breaker and is energized whenever the generator is operating and connected
to the transfer switch regardless of Circuit A switch position.
– Each circuit has
a push-to-reset circuit breaker that is active when the Switch is in the
GEN position. In the LINE position, each circuit is protected by the breaker
in the load center. The circuits on the transfer switch must be
connected to identically sized circuits in
the house panel. 15 amp to 15 Amp, 20 amp to 20 Amp and so forth. 20 amp
circuits in the house panel.
– Indicate the circuit loads,
in watts, when the generator is supplying power. The left meter measures
the load on circuits on the left and the right meter measures the load on
circuits, on the right.
- Be sure to have
all tools listed above.
- Transfer switch
can be installed on either the left or right side of your house electrical
panel (also called load center). Hold the transfer switch up to the
wall about 18" from the center of the load center to ensure adequate
room. Remove the cover of the load center. CAUTION: All wires are live
inside load center! MAIN circuit breakers
should be turned off to ensure safety. Remember, all wires on
"line" side of main are still hot.
- Locate and remove a
knockout in the bottom of the load center near the center, if possible.
Use a 3/4" (trade size) knockout for 15 amp models and use 1" knockout
for larger amperage models.
- Insert all wires from
transfer switch at end of flexible conduit through knockout and install
- Anchor transfer
switch to wall using the external feet. Do not over-bend flexible conduit.
the Transfer Switch to the
- Determine which circuits
you will want to use during an emergency (see wattage listing). Choose
6 circuits if you are installing a 6-circuit transfer switch, choose
10 circuits if installing a 10-circuit unit and so on. We suggest you
wire the most critical circuits first, starting with "A".
- Assuming you want to
designate your Furnace as "A", turn the Furnace circuit breaker OFF
and loosen the screw which secures this wire into the circuit breaker
and remove wire.
- On the transfer switch,
find the Black and Red wires marked "A". Feed these two wires to the
selected breaker (Furnace). Cut Red wire "A" to a convenient length,
strip approximately 5/8", install in circuit breaker and retighten screw.
Take Black lead "A", cut to convenient length to match up with wire
removed from circuit breaker. Strip 5/8" and insert both wires into
yellow wire connector. Twist on tightly, push wires back into side of
- Repeat steps 2 and 3
above to wire remaining circuits.
- To install the handle
tie on the 240 volt circuits on the 6-, 8- or 10-circuit models, locate
the Red and Black wires for the circuits with the handle tie. Turn off
the 2-pole breaker in the load center and remove wires as above. Feed
wires from handle-tied switches to the 2-pole breaker as above. Cut
and strip 5/8". Insert red wires in breaker and tighten. Black wires
connected as above.
- If you have no 240-volt
circuits in your load center, the double pole handle-tied circuits on
the transfer switch are not needed. Turn the handle-tied switches to
the GEN position. Loosen the two screws on the handle tie, remove the
handle tie and discard. These circuits may now be used as 1-pole circuits
as you select.
- Once you have wired
all circuits in the switch, only the White neutral wire and Green ground
wire remain. Insert the White neutral wire into an unused hole in the
neutral bar in the load center and tighten. Then insert the Green ground
wire into an unused hole in the ground bar, if existing and tighten.
If no ground bar exists, insert the Green wire into an unused hole in
the neutral bar and tighten.
- Replace the cover to
the load center. Fill in the chart on the top of the transfer switch
to describe your emergency circuits and related circuit numbers in the
load center. Turn ON all breakers in the load center and turn all switches
on the transfer switch to the LINE position. Installation is now complete.
Note on hardwire model installation:
Some models have been designed to "hardwired" to a power inlet
box located remotely from the transfer switch. We offer Power
Inlet Boxes. Usually there is a terminal block located in the
wiring compartment of which is marked for connection to the
remote power inlet box (often called power IN) and is typically
labeled as follows:
Terminal: To Power Inlet "X" or "Y" terminal
Terminal: To Power Inlet Neutral "W" terminal
Terminal: To Power Inlet "X" or "Y" terminal
Terminal: To Power Inlet Ground "G" terminal
Note on convenience outlet:
manual transfer switches have a 3-wire, grounded convenience
outlet, to be used for tools or lights near the transfer switch
installation during an outage. This outlet is connected to circuit
breaker "A" on the transfer switch and must be calculated with
other load on circuit A.
Using Your Transfer Switch
and Your Portable Generator
|To ensure that your generator
will always be ready when you need it, it is important to start and run
your generator UNDER LOAD regularly and keep the tank filled with fresh
fuel. Perform the following steps at least ONCE A MONTH to keep the generator
properly "exercised". It is not necessary to turn off any circuits in the
Main load center when supplying generator power with the transfer switch,
even when the utility power is operating normally. The double-throw switches
prevent back-feeding generator power to the utility and, conversely, utility
power to the generator.

- Plug in the female connector
of the Power Cord to the Power Inlet Box OR transfer switch. Be sure
that all switches on the Transfer Switch are in the
- Insert the male
connector of the Power Cord into the outlet on the generator.
- Start the generator
outdoors, following the procedures described in the generator’s owner’s
manual furnished by the manufacturer.
- Select the circuits
to be powered by the generator by moving the corresponding switches
to the GEN
position. Use only necessary household items when under generator power

each circuit is limited by the main circuit breaker, to a maximum of
the switch. If you have selected circuits that draw more than the total permitted by the
main circuit breaker, it will be necessary to selectively turn off some
of the loads on that circuit in order not to exceed the capacity of
the main circuit breaker. Test your circuits by using the wattmeters
or determine wattage from that shown on each appliance. Make a note
of any excessive loads which must be removed from a given circuit during
