Generator AC Load Connections
CAUTION
All 120/240 volt loads must be divided up and connected in such a manner that current flow-
ing in any of the hot legs does not exceed the lowest amperage rating on the generator's data
plate.
The generator's data plate gives the voltage, amperage and hertz rating of the generator. The generator set
AC wiring decal located on the cover of the generator-mounted control panel shows the electrical connec-
tions for 120 or 24O-volt AC output.
These generator sets have a single phase, 4 lead with voltage combinations of 120-volt, two wire, or 120/240-
volt, three wire. All 120-volt devices must be connected to one of the two 120-volt sources and all 240-volt
devices must be connected tothe 24O-volt source. For all 120-volt loads, half ofthe generator's rated capacity
may be taken from leads L 1 and half from L2. 24O-volt loads are connected to L1 and L2 at full generator
rated capacity.
NOTE: It is recommended that the installer offer instrumentation (that is, an AC ampmeter
which is optional equipment) so the operator can monitor and determine the load while it is
taken from the generator.
A circuit breaker should be installed between the generator and the AC load. This circuit breaker should be
rated for the generator's AC output and be able to react quickly to overloads, subject to motor starting con-
siderations.
