1. Introduction
The Go Power! Electric Transfer Switch-30 amp (TS-30) provides automatic power
switching between two separate 120 volt AC input sources, including power cords,
onboard generators, or onboard inverters. The TS-30 will sense the presence of
available supplies and automatically select the proper one.
The TS-30 can be installed at the electrical entry of the RV on the line side of the
main distribution panel, or it can be installed on the load side of the panel between
the main panel and a sub panel, allowing switching for either the entire electrical
load or only designated circuits.
2. INSTALLATION
READ AND FOLLOW ALL SAFETY INSTRUCTIONS
2.1 DISCONNECT POWER
Make sure the generator is off, the external power cord is unplugged, and the
inverter, if any, is shut off.
2.2 MOUNTING LOCATION
The TS-30 mounting location may be on any interior surface where the unit will be
out of direct weather. The chosen location must be accessible after installation is
complete to facilitate future servicing. If possible, mount the TS-30 near the power
cord entry or the location of the generator output. Typical locations include under
counter cabinets, below closet compartments, inside the bed pedestal or cabinets,
overhead cabinets, under-floor storage compartments accessed from the vehicle
exterior, etc.
2.3 ELECTRICAL PREPARATION
Any numbered knockout on the TS-30 can be used for installation. Choose a
knockout that will facilitate installation and service within the selected mounting
area.
2.4 MOUNTING
Mount the TS-30 with screws through holes provided in bottom corners of the can.
The unit should be screwed to a solid surface firmly enough to hold its weight during
vehicle operation.
2.5 ELECTRICAL CONNECTIONS
1. Attach an 8-gauge chassis ground wire to the transfer switch ground bar. A
direct access hole to the ground bar is provided through the enclosure for
convenience.
2. Determine proper connections of wire conductors to electrical terminals. On 120
VAC wiring the ground wire is bare or green, the neutral wire is white, and the
hot wire is black.
3. Strip the outer jacket from all of the incoming cables and strip insulation from all
ends of the copper conductors. Insert cables through clamps in openings. Do
not tighten cable clamps at this time.
4. Route internal ground wires around lower area of enclosure and secure to
ground wires away from electrical contacts on components to avoid the
possibility of electrical short-circuit.
5. Connect the ground wires to the ground bar. Tighten terminals to a minimum of
20 inch-pounds.
CAUTION:

to foreign
contaminants, do not
mount the transfer
switch in an engine
compartment under

6. Connect the neutral (white) wire connections.
7. Connect the hot wire(s) (black).
8. To connect the wire leads, hold the wires parallel to each other so that the wire
tips are even, then secure with a wire nut. Use the proper size nut. Manually
tighten nuts as tightly as possible. Verify that all connections are tightened.
9. Tighten cable clamps on switch enclosure.
10. Attach lid. The lid is designed to snap on and should not open without deliberate
effort.
2.5.1 INSTALLATION BETWEEN POWERCORD AND GENERATOR
(CONFIGURATIONS A, B)
1. Connect the power cord leads to terminal 7 and 8 (on the narrow end of the
relay); these are the normally closed (N.C.) contacts.
2. Connect the generator leads to terminals 5 and 6 (on the shoulders of the
relay); these are the normally open (N.O.) contacts.
3. Connect output to panel to terminals 3 and 4 (on the wide end of the relay). The
TS-30 is designed with a time delay module to provide generators a brief warm-
up period before supplying the load. The bypass switch on the time delay
module should be in the “off” position (marked “1”). See Diagram 1.

2.5.2 INSTALLATION BETWEEN INVERTER AND ALTERNATING
SOURCE (CONFIGURATION C)
1. For installation between inverter (default) and another power supply (dominant),
such as the output from a prior power cord/ generator transfer switch. These
connections will allow any other supply to dominate the inverter, and the inverter
output will pass through the normally closed contacts of the switch. This allows
the inverter to operate only in the absence of the other power supplies, which is
ideal for inverters.
2. Connect the inverter to terminals 7 and 8, and connect the other power supply
to 5 and 6. Output terminals always remain the same.
3. Set the timer delay bypass switch of the inverter/alternate source transfer switch
to the ON position. See Diagram 2.

2.5.3 INSTALLATION IN HYBRID SYSTEM FOR DESIGNATED
CIRCUITS (CONFIGURATION D)
The TS-30 A can be installed between inverter (default) and a circuit
panel supplied by a larger amp alternating power supply (dominant).
1. Connect the inverter to terminals 7 and 8.
2. Connect the 30-amp branch circuit to 5 and 6.
3. Connect the designated circuit panel to the output terminals.
The inverter will only supply the load in the absence of the 50 amp
power supply, in which case, only the load designated to the 30 amp
branch circuit is supplied. The timer delay bypass switch on the TS-30
should be in the ON position.
3. OPERATIONAL TESTING
READ AND FOLLOW ALL SAFETY INSTRUCTIONS
1. Plug in the power cord. If the main panel circuit breakers are
switched on, RV load should operate normally. Unplug the power
cord.
2. Start the generator. There is a pre-programmed 20-30 second delay in the
transfer switch. The delay is designed to allow the generator a brief warm-up
period. When the delay completes its cycle the switch should engage and the
RV load should operate normally. An audible click should sound as the switch
engages.
3. Shut down the generator. As the generator winds down the switch should
disengage without chatter or cycling. An audible click should sound as the
switch disengages.
4. Plug in the power cord. Start the generator. After the preprogrammed delay, the
switch should transfer power automatically from the power cord to the
generator. Listen for the audible click as the switch transfers, as there will likely
be no other indication that the switch has engaged. Shut down the generator
and unplug the powercord.
5. On transfer switch arrangements with three power supplies, plug in the power
cord, start the generator, and turn on the inverter. With all three supplies
energized at the same time, the switch will select the generator for the primary
supply choice. Shut down the generator. The switch will transfer to the power
cord. Unplug the power cord. The switch will transfer to the inverter. The
inverter should always be connected so that it is only selected in the absence of
both the other supplies.
4. TROUBLESHOOTING
4.1 LOW VOLTAGE
Low voltage is harmful to most appliances. Contactor-based transfer switches are
also affected by low voltage; if the voltage level drops far enough the contactor
points will “chatter”. Sustained contact chattering can cause transfer switch damage.
Switches that have been damaged by chattering need to be returned to the factory
for replacement.
4.2 GENERAL LOW VOLTAGE
Low voltage can be caused by low voltage conditions such as an RV park with
inadequate wiring for crowded camper conditions where everyone’s electricity
suffers (brownout). In this case a voltmeter will be helpful and will show a low
voltage reading from the park receptacle, even before the RV is plugged in. When

you experience general low voltage conditions, remember that brownouts can be
harmful to most appliances. A better alternative might be to utilize the generator until
park voltage conditions improve.
4.3 LOCALIZED LOW VOLTAGE
Low voltage conditions can be caused by specific situations such as an additional
cord, which is too long and too small for the load. Do not attempt to extend the RV
power cord by using a 16-gauge 100-foot extension cord, or any cord not rated for
an RV-size load. A localized low voltage condition will result when a load is turned
on which is larger than that which the cord is designed for. As soon as the RV tries
to draw more current than the amount for which the cord is rated, the voltage will fall
within the length of the cord, and the RV will experience low voltage. This is
especially noticeable during in rush current situations such as an air conditioner
start-up.
This affects contactor-based transfer switches. The compressor will try to start; the
voltage will drop, which will cause the contactor to drop out, at which point the
voltage will rise to the pre-in rush level. The contacts will chatter when the A/C
compressor kicks in, however the voltage may read normal. Most meters are not
fast enough to record this voltage drop. You can test for low voltage readings during
this inrush cycle by reading voltage at the contactor terminals while manually
holding the contactor plunger down in its closed position. This will override the
chattering condition and the meter will have time to register the reduced voltage. If
this condition exists, identify and correct the low voltage situation before proceeding
further.
4.4 PHYSICAL INTERFERENCE
Some transfer switch models have wiring connections made by wire nuts on 6″
leads. Occasionally on these models, the wiring connections will get folded into the
can in such a manner that the wiring will interfere with the physical operation of the
relay. Visually inspect for free operation of the relay(s).
4.5 TIME DELAY BYPASS SWITCH
The time delay function in the control module on some models may be bypassed.
Relay-based transfer switches have incorporated into the control module board a
small switch, which allows the technician to activate or bypass the time delay. The
time delay is necessary during generator start-up so that the generator does not
have to start under load; the delay is not necessary for power cords or inverters.
Therefore in transfer switch operation where the module is controlling a supply other
than a generator, the delay switch should be set to the bypass (ON) position. This
will allow instantaneous switching. Another time for bypassing the delay is during
diagnostic and troubleshooting efforts; if bypassing the delay causes the switch to
work when it otherwise won’t, then the time delay has malfunctioned and the board
should be replaced. To bypass the time delay, locate the switch on the end of the
circuit board and select the position on the switch marked ON. Time delay bypass is
now activated, and transfer will be instantaneous.
4.6 FAILED TIME DELAY CONTROL MODULE
It is possible for a voltage spike, etc. to cause the time delay module to fail: if this
happens the switch will no longer transfer. Transfer Switch models have a
diagnostic LED mounted on the control module circuit board. If the module is
receiving 120 VAC input and is operating properly, the LED will be lit. This means
the control module has timed for the 20-30 second delay and is now providing
power to the coil on the relay. If the module input is energized and the LED does not

Owner’s Manual
8
light after 30 seconds, the time delay function in the module has failed, and the
module should be replaced. To verify this, try setting the time delay switch on the
board to the delay bypass position; the switch should transfer with no delay. Note
that this position will allow emergency operation until the module can be replaced;
however there will not be a 20-30 second delay for generator start-up. All repairs
should begin by unplugging and replacing the control module first. However, if the
LED is on and the switch is not working, then the control module is functioning
properly and the switch has other problems, such as a failed relay or contactor, and
the entire switch should be returned for replacement.
5. HI-POT TESTING
(MANUFACTURING COMPANIES ONLY)
NOTE: If the hi-pot test is performed from the plug on the power cord, the test may
only hi-pot the cord itself; it may not test the RV wiring beyond the switch. The hi-pot
test should be performed from either the transfer switch output or from the main
panel.
Test as follows:
1. Turn on all circuit breakers in the panel.
2. Make sure the generator is off.
3. Make sure the power cord is unplugged. Verify that the prongs on the power
cord plug are protected so that the hi-pot voltage won’t cause a fault reading
from a short, or cause bodily injury from electrical shock.
4. Turn off or disconnect all appliances that would be damaged by the hi-pot test.
5. Connect the hi-pot leads to:
a) Transfer switch ground bar
b) Transfer switch output terminals hot 1, hot 2 (if present), and neutral.
6. Energize the hi-pot and conduct test. This will hi-pot test for leakage (short)
between the current-carrying conductors and the ground in the entire 120/240
VAC circuitry beyond the transfer switch. In most cases it will also test the
power cord itself. Turn off the hi-pot.
7. Do not test the transfer switch generator input. The hi-pot will damage the
time delay control module in the transfer switch. If the generator wires to the
switch must be checked, disconnect the generator wires from the transfer
switch and connect hi-pot test leads to the loose wires. Reconnect wires after
testing.
8. If hi-pot test fails, there is a short in the system. The next step is to isolate the
location of the short. Turn off the main breaker in panel and hi-pot test again. If
the test still fails, the fault is between the switch and the panel. Test cord for
shorted plug. If the test passes, turn on the main breaker, and turn on all branch
breakers except one. Retest each branch circuit individually until the shorted
circuit is isolated. Repair the fault and retest. The hi-pot test is successful when
there are no more fault indications.
6. GENERATOR NOTE
It is never advisable to start or stop a generator under load. To prolong the life of
this transfer switch, and the life of the air conditioner, microwave oven, and other
appliances, always turn those appliances off before starting or stopping the
generator.
7. MEDICAL APPLIANCES
Go Power! Electric will not knowingly sell a Go Power! Automatic Transfer Switch
for any life-support application. It is strongly recommended that you do not operate
any life support equipment from a transfer switch. If the switch should malfunction,

Go Power! TS-30

or fail to operate due to other external conditions, it is possible that all connected
appliances, including any life support equipment, will also shut down, resulting in a
risk of medical complications and potential loss of life.
8. CAUTION
Do not install this or any electrical accessory in the battery compartment, or a
compartment intended for storing flammable liquids or liquids, which produce
flammable or explosive fumes such as gasoline, etc. There are components in the
Transfer Switch, which, in their normal operation, may cause arcing. In addition, the
act of turning on a light switch or unplugging the cord on an electrical appliance can
cause a spark, which can ignite any combustible liquids or vapors. Therefore, do
not install a transfer switch in a compartment intended for storing flammable
liquids, and never store flammable liquids inside a compartment containing
any electrical device.
