Power Wiring Interconnections - Briggs & Stratton 071038 Guide D'installation Et D'utilisation

Power Wiring Interconnections

All wiring must be the proper size, properly supported
and protected by conduit. All wiring should be done per
applicable federal, state and local codes, standards and
regulations. Obey wire type and torque specifications printed
on the terminal blocks and neutral/ground connector.
WARNING Shock Hazard. Installing low and high
voltage wiring in same conduit could result in
death, serious injury and/or property damage.
• Do not run low and high voltage wiring in the same
conduit unless the insulation rating on ALL wiring is rated
for 600V AND the length of the conduit is 30 ft. or less.
See NEC for more information.
Complete the following connections between the transfer
switch, main distribution panel, generator and sub-panel.
Use installer-supplied 300VAC or greater wire that complies
with Table 310.16 in the National Electric Code. Apply the
necessary correction factors and wire size calculations.
NOTICE Improper installation could cause damage to the
circuit boards and shorten their life. Installing circuit boards
in live circuits will damage the board and is not covered by
warranty. ALWAYS disconnect ALL sources of power prior
to servicing.
• Remove all power prior to installing this equipment. Failure
to do so could cause internal damage to the board when
making electrical connections.
• Turn generator to OFF position.
• Turn off utility power to the standby generator and
transfer switch.
1. Set generator's circuit breaker to OFF (open) position.
2. Set generator's system switch to OFF position and
remove 15 Amp fuse from system control panel.
WARNING Battery posts, terminals and related
accessories contain lead and lead compounds, chemicals
known to the State of California to cause cancer and
reproductive harm. Wash hands after handling.
3. Ensure utility power to the standby generator and
transfer switch is disconnected.
4. Using installer supplied 300VAC or greater copper
conductor, connect utility power from a suitably-rated
two pole breaker installed in main distribution panel to
transfer switch contactor terminals marked "UTILITY".
Ensure circuit breaker is turned OFF.
5. Using installer supplied 300VAC or greater copper
conductor, connect main distribution panel ground to
transfer switch "GROUND" bus.
Assure grounding electrode conductor is connected
and bonded per applicable federal, state and local
codes, standards and regulations.
6. Using installer supplied 300VAC or greater copper
conductor, connect main distribution panel neutral

(B) will be neutral to sub-panel. (C) will be neutral
to generator.
7. Using installer supplied 300VAC or greater copper
conductor, connect transfer switch contactor terminals
marked "LOAD" to sub-panel.
8. Using installer supplied 300VAC or greater copper
conductor, connect transfer switch "GROUND" terminal
to sub-panel ground bus.
9. Using installer supplied 300VAC or greater copper
conductor, connect transfer switch "NEUTRAL" terminal
(B, above) to sub-panel neutral bus.

conductor, connect transfer switch contactor terminals
marked "GENERATOR" to generator circuit breaker
LINE1 and LINE2 terminals. Each conductor must
pass through hole of current transformer inside transfer
switch enclosure.

11. Plug current transformer leads into "CT1" and "CT2"
terminals on transfer switch control board.
12. Using installer supplied 300VAC or greater copper
conductor, connect transfer switch "NEUTRAL" terminal
to generator "NEUTRAL" terminal. Observe generator
control panel labeling for terminal identification.
