BEFORE USING THE ST SWITCH
COMPATIBLE GENERATORS
The ST Switch will only work with generators that have
this Smart Switch Ready outlet. This product will not
work with any other generators. Please see Smart Switch
outlet below.
UNDERSTANDING POWER OUTPUT AND
DEMAND OF APPLIANCES
120 Volt AC devices have two different electric power
demands that must be taken into consideration, namely
the running power and the starting/peak power. Both are
measured in Watts (typically abbreviated as “W”).
The steady state continuous load is the running power
demand and this is often marked on the device near
its model number or serial number. Sometimes the
device might only be marked with its voltage (i.e. 120V)
and current draw (e.g. 6 Amp or 6A), in which case the
running power demand in Watts can be obtained by
multiplying the voltage times the current, e.g. 120V × 6A
= 720W.
Simple resistive 120 Volt AC devices such as
incandescent bulbs, toasters, heaters, etc. have no extra
power demand when starting, and so their starting power
demands are the same as their running power demands.
More complex 120 Volt AC devices containing inductive
or capacitive elements such as electric motors have a
momentary extra power demand when starting, which
can be up to seven times the running power demand
or more. Manufacturers of such devices rarely publish
this starting power demand and so it’s often necessary
to estimate it. A rule of thumb for devices fitted with an
electric motor is to apply a starting power multiplier of
1.2 for small hand-held or portable devices and a value
of 3.5 for larger stationary devices. For example, a 900W
angle grinder can be assumed to have a starting power
demand of at least 1.2 × 900W, which equals 1,080W.
OPERATION
To prevent overloading of the ST Switches 120 Volt AC
system add up the running power demand of all the
120 Volt AC devices that will be connected to the ST
Switch at one time. This total must not be greater than
the power output of the utility power.
RECOMMENDED USE
NOTICE
The list of appliances below is a general guideline.
Always check the wattage of the devices you are
trying to power as ratings may vary. Always test to
confirm ST Switch is not overloaded by appliance
power demands.
When adding up power demands of appliances do
not exceed the rated output of your utility power.
The table below are common appliances that can be
individually powered by the ST Switch. Wattages are
estimations.

HOW IT WORKS
BEFORE USING ST SWITCH PLEASE REVIEW ALL SAFETY INFORMATION AND
CONFIRM ST SWITCH AND GENERATOR ARE WORKING CORRECTLY
WHEN UTILITY POWER IS ON:
When home utility power is on it will provide power to the appliances plugged into the 5-20R duplex on the ST
Switch box up to 120V at 20A. The green utility power indicator light will illuminate on the ST Switch box when
utility power is on. The generator will remain off with the engine control switch in the RUN position and the utility
power will charge the battery through the generator control cable. See image below for flow of electricity when
utility power is on.

WHEN UTILITY POWER IS LOST:
As soon at utility power is lost the utility loss indicator light will illuminate red. 5-10 seconds after utility loss the
ST Switch will turn the generator on. Once the generator has successfully started the ST Switch will transfer input
power from utility to generator power. The generator power indicator will illuminate green when appliances that are
plugged into the ST Switch are being powered by the generator. The utility loss indicator will remain red as long as
utility power is off. See image below for flow of electricity when utility power is off and generator power is on.

OPERATION
WHEN UTILITY POWER COMES BACK ON:
After an outage when utility power returns the ST Switch will run a quick diagnostic to confirm there are no spikes
or flickering in the utility power before transferring input power back to utility. Once utility is returned the red utility
loss indicator light will turn off and the utility and generator power indicator lights will remain on. After power has
been transfered back to utility power, the ST Switch will allow the generator 45-50 seconds to cool down before
shutting it off. Once the generator has shut down the green generator power indicator light will turn off.
NOTE: If utility power is lost during the generator cool down phase the ST Switch will wait a couple of seconds and
transfer input power back to generator power until utility power is restored.
ST SWITCH INDICATOR LIGHTS
Lights Displayed Description
Input power for appliances plugged into the ST Switch is being
provided by utility power.
Utility power has been lost and there is no power being provided to
appliances plugged into the ST Switch. In 5-10 seconds of this light
being on the ST Switch will turn the generator on.
Utility power is o and power to appliances plugged into the ST
Switch is being provided by generator.
Utility power has come back on but ST Switch is running diagnostic
to make sure power is steady before transferring. This diagnostic
usually takes 5-10 seconds and then the red utility loss light should
turn o.
Generator is in cool down stages before shutting o. This takes 45-
50 seconds after the red utility loss indicator turns o.

14
OPERATION
HOW TO TEST THE ST SWITCH
