WIRING THE EMERGENCY TRANSFER
SERVICE KIT
WARNING - PERSONAL INJURY
All wiring must be done by a licensed electrician, and
must conform to the national electrical code and comply
with all state and local codes and regulations. Check
with your local electrical inspectors before proceeding!
PREPARATION
Before doing any wiring you must decide which circuits
you want to back up. As discussed earlier you will have
a limited number of circuits that can be moved from your
primary distribution panel to the Emergency Load
Distribution Panel.
The primary thing to remember when you are selecting
your circuits is that the generator has a very limited
amperage capability. What this means is that your
combined load on the generator cannot exceed the
nameplate rating on either power feed of your generator.
Also take into account any electric motors that you are
going to operate. Motor loads have a very high amper-
age inrush when the motors first start up. If you don't
have sufficient generator capability with your other loads
running, the motor will stall and possibly do damage to
the motor or other connected loads.
EMERGENCY TRANSFER SERVICE
The Emergency Transfer Service kit includes a UL
Approved Square 'D' manual power isolation switch.
When properly installed it will safely disconnect the
normal power service from your home emergency
electrical circuits and reconnect them to a portable
generator. It is not designed to transfer your whole
electrical system, only selected circuits you need
powered during a power failure (i.e. furnace, refrigera-
tor, freezer and minimal lighting). This system is
comprised of three major parts. The manual transfer
center, exterior 'J' (junction) box for connections and
cord storage and the 12' four wire cord set with the plug
installed.
The manual transfer center is built around two 60 amp
backfeed Square "D" circuit breakers with a mechanical
interlock bar installed. Manual transfer center also has
additional space for the customer to install two 240 volt
breakers, or one 240 volt and two 120 volt breakers or
four 120 volt breakers. The load center uses standard
Square D circuit breakers type QO and Q1. The 120
volt breakers may be replace with type QO-T circuit
breakers, providing up to eight 120 volt circuits.
Before beginning the installation process it is very
important to plan which circuits you want to move from
your main circuit breaker panel into the manual emer-
gency transfer panel. That way you can purchase only
the breakers you need and will have room for everything
when you are completed.
