System Connectors - Briggs & Stratton 40336 Installation & Start-Up Manual

System Connectors

Low Voltage connections to signal fault contacts, transfer switch communication and auxiliary 12VDC power are made via a
field connection terminal block in control board area. Compare this illustration with your generator to familiarize yourself
with the location of these connections.
A - Two Pin Terminal Block — Used to connect utility
240 VAC from fuse block in ATS to the control board.
Connect only one wire per terminal.
B - Fault Contacts — Use NO, COM and NC to hook up a
siren, light, etc. to alert you in case of a fault. Contacts
reverse state (NO goes to NC and vice versa) upon a
fault condition.
C - Transfer Switch Communication (TxRx and TxRx
GND) — Connect to transfer switch control board for
communication interface using 18AWG twisted pair
wire.
• For power output connection (Line 1, Line 2, Neutral, and Ground), 300V, 6 AWG copper wire, or 300V, 4 AWG aluminum wire, (ref.
NEC Table 310.16, 100 ft. Use National Electric Code for correction factors and wire size calculations).
• For utility circuit connection (Utility A and Utility B) use #14 AWG minimum copper 300 volt 90°C wire or 300V, 4 AWG aluminum wire.
• For transfer switch communication use #18 AWG twisted pair conductors, no greater than 200 ft in length, 300 volt 90°C wire.
• When connecting to the terminal block, fasten only one wire to each connector screw.
• Torque terminal block screws to 4.4 in-lb (0.49 Newton meter).
• Torque circuit breaker connections to 45 in-lb (5 Newton meter).
