Connecting Power Source And Load Lines; Connecting Front Panel Wiring; Installing Branch Circuit Conductors - Usa Installations - Generac Power Systems 006852 Owner's Manual

Section 3: Installation
Strip and insert incoming leads into terminals on
5.
power inlet. Insert white wire (neutral) into nickel
plated screw terminal or white marking on the inlet.
Carefully fold wires into the enclosure and reattach
6.
the bottom assembly or inlet onto box with screw
removed earlier.
Connecting Power Source and
Load Lines
DANGER
Electrocution. Turn utility and emergency
power supplies to OFF before connecting
power source and load lines. Failure to do so
will result in death or serious injury.
Installation and interconnection diagrams are provided in
the Drawings and Diagrams
NOTE: All installations must comply with national, state
and local codes. It is the responsibility of the installer to
perform an installation that will pass the final electrical
inspection.
The utility supply, generator, and customer load
connections are made at the transfer switch mechanism,
inside the switch enclosure.
Conductor sizes must be adequate to handle the
maximum current to which they will be subjected, based
on the 75°C column of tables, charts, etc. used to size
conductors. The installation must comply fully with all
applicable codes, standards and regulations.
NOTE: If aluminum conductors are used, apply corrosion
inhibitor to conductors. After tightening terminal lugs,
carefully wipe away any excess corrosion inhibitor.
Tighten terminal lugs to the torque values as noted on the
inside of the door.
CAUTION
Equipment damage. Verify all conductors are
tightened to the factory specified torque value.
Failure to do so could result in damage
to the switch base.
Connect power source and load conductors to clearly
marked terminal lugs on transfer mechanism as follows:
Install a 2-pole, 50 Amp breaker in the main distri-
1.
bution panel. This will be the utility (normal) power
source for transfer switch.
Customer LOAD leads are pre-wired at the factory.
2.
NOTE: Conductors must be properly supported, of
approved insulative qualities, protected by approved
conduit, and of the correct wire gauge size in accordance
with applicable codes.

Connecting Front Panel Wiring

Utilize the quick disconnect connector in the wiring
harness to remove the front panel during service or
installation. Verify that power and load lines are
disconnected any time the front panel is removed.
Installing Branch Circuit
Conductors – USA Installations
Select which branch circuits will be protected by
1.
the generator in the normal power panel board.
Turn the circuit breaker in the normal power panel
2.
board to the off position.
Remove the ungrounded (hot) conductor from the
3.
circuit breaker and neutral conductor from the
neutral terminal bar in the normal power panel
board.
NOTE: Multi-wire branch circuits must be connected to
circuit breakers that are adjacent to each other. If the
circuit to be protected is part of a multi-wire branch circuit,
the entire multi-wire branch circuit must be relocated to
the transfer switch panel board (See NEC 210.4). The
branch circuit wiring can be removed from the normal
power panel board and installed in the transfer switch
panel board, or spliced onto new branch circuit wiring
originating from the transfer switch panel board.
If the normal power panel board is being used as a
4.
junction box for the protected branch circuit
conductors, install the 2 foot conduit, raceway(s),
or other approved wiring method between the
transfer switch panel board and normal power
panel board.
Install properly sized branch circuit conductors
5.
between the transfer switch panel board to the
branch circuit conductors to be protected by the
transfer switch, if not using factory supplied wiring.
Use listed wire nuts or any other approved
6.
termination device to connect the branch circuit
conductors.
Install the provided label on the existing panel
7.
board that indicates
disconnecting means
conductors.
If the generator protected branch circuit conductors
8.
are being re-installed into the transfer switch panel
board, punch the required sized hole(s) for the
cable, conduit, or raceway.
Route the branch circuit conductors into the
9.
transfer switch and terminate the equipment
ground conductor on the equipment ground
terminal bar, the neutral on the neutral terminal bar,
and the ungrounded (hot) on the circuit breaker
terminal.
