Mounting Guidelines; Power Wiring Interconnections - Briggs & Stratton 71047 Manuel D'installation Et D'utilisation

Mounting Guidelines

The system circuitry is enclosed in a NEMA Type 3R
enclosure suitable for indoor/outdoor use. Guidelines for
mounting the enclosure include:
• Install enclosure on a firm, sturdy supporting structure.
• The enclosure must be installed with minimum
NEMA 3R hardware for conduit connections.
• To prevent switch contact distortion, level and plumb
the enclosure. This can be done by placing washers
between the enclosure and the mounting surface.
• NEVER install the switch where any corrosive
substance might drip onto the enclosure.
• Protect the switch at all times against excessive
moisture, dust, dirt, lint, construction grit and
corrosive vapors.
It is best if the transfer switch is mounted near the utility
meter, either inside or outside. Discuss layout suggestions/
changes with the owner before beginning the system
installation process.

Power Wiring Interconnections

Utility and generator conduits must enter enclosure above
circuit breaker bus in transfer switch. No conductors shall
pass over top of control board. Branch circuit conduits
must enter sides or bottom of enclosure adjacent to circuit
breaker terminals. Do Not use large knockouts in bottom
of enclosure.
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 Low voltage wire cannot be installed in
same conduit as power voltage wiring.
• Failure to follow above warning could cause personal
injury, damage and/or malfunction of equipment.
Complete the following connections between the transfer
switch, main distribution panel and generator. 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 can 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.
3. Turn off utility power to the standby generator and
transfer switch.
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.
4. Using installer supplied 300VAC or greater copper
conductor, connect utility source from an installer-
supplied 100 Amp two pole "essential circuit 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.
6. Using installer supplied 300VAC or greater copper
conductor, connect main distribution panel neutral to
transfer switch NEUTRAL bus.
