WYE POWER
In simple terms in reference to a three-phase system, it would be a five-wire system (three hot wires, a neutral
wire, and a ground wire) . A wye connection utilizes a star connection . Measuring voltage on a wye system will
give you around 120v to ground on all three hot legs or between 208-240v when measuring between hot legs .
NEMA TYPE 1
This is an indoor rated enclosure that is providing protection to the equipment inside from typical indoor
contaminates such as dirt or other solid falling objects .
NEMA TYPE 3R
This is an outdoor rated enclosure that is providing protection to the equipment inside from falling rain, sleet,

TEFC
Stands for Totally Enclosed Fan Cooled . This is a type of electric generator enclosure that does not allow outside
air to circulate through the interior of the generator . Instead, it uses an externally mounted fan that blows air
over the frame to cool it . With this enclosure, you can mount the electric generator/idler outdoor without the
need for an additional enclosure around it .
IDLER JUNCTION BOX
Also referred to as the J-Box . This is the box on the side or top of the electric generator/idler where the wire
connection points are made . The junction box has a knockout where you can run the wires through and
secure using a wire clamp or compression connectors . The front of the junction box will open to allow the wire
connections to be made .
INSULATING WIRE CONNECTIONS
This is the process of covering any wire connection points that are typically using metal with a non-conductive
material . This process typically utilizes the use of rubber mastic tape, heat shrink tubing, or standard electrical
tape .
CURRENT
The rate of which electricity travels through a set point .
REGENERATIVE CURRENT
Extra current or ghost current that is created when there are motors on a system . They can add current back
into the line which can cause an amp meter to give an inaccurate reading and read higher than the actual
amount of current being utilized .
