Introduction
The Eaton 10 Circuit Manual Transfer Switch is
intended to be used with Eaton generators but
may be used with any generators. These Manual
Transfer Switches are rated for 50 amp utility input
and 30 amp or 50 amp generator input respec-
tively at 240 Vac. These devices come equipped
to power nine emergency circuits. There are eight
single-pole emergency circuit breakers and one
2- pole emergency circuit breaker included.
These devices are intended for use with genera-
tors that are wired as either Separately Derived
systems (neutral and ground bonded together
at the generator – typically protected by a GFCI,
ground fault circuit interrupter, on the generator)
or Non-Separately Derived systems (neutral and
ground are NOT bonded at the generator). Refer
to the NFPA 70, National Electrical Code, for
proper connection and further definition.
Contact the generator manufacturer if you
are unsure how the generator is configured
(Separately Derived or Non-Separately Derived). It
is extremely important that you know this informa-
tion prior to connecting the generator to this or
any other transfer switch.

Figure 1. Manual Transfer Switch with Door Open.
These Manual Transfer Switches utilize 3-pole switching devices to
determine which power source, utility or generator, are powering
the nine emergency circuits. The 3-pole switching devices are inter-
locked via a manual slide type interlock. The intent of the interlock is
to ensure that only ONE source is powering the emergency circuits
and to prevent back feeding of the utility with the generator or inad-
vertent paralleling of the utility and generator sources.
Figure 2. Connection Locations for a Separately Derived System.
Connection for a Separately Derived System:
1. For generators that are configured as a Separately Derived
system. These units typically contain GFCI protection on the
generator.
a. Connect the two hot wires from the utility to the utility
breaker poles #1 and #2. Connect the utility neutral to the
utility breaker pole #3. See Figure 2 for clarification.
b. Connect the two hot wires from the generator to the
generator breaker poles #1 and #2. Connect the generator
neutral to the generator breaker pole #3. See Figure 2 for
clarification.

2. For portable generators that are configured as a
Non- Separately Derived system.
a. Connect the two hot wires from the utility to the utility
breaker poles #1 and #2. Connect the utility neutral to the
utility neutral lug. See Figure 3 for clarification.
b. Connect the two hot wires from the generator to the gen-
erator breaker poles #1 and #2. Connect the generator
neutral to the neutral bar. See Figure 3 for clarification.
