Wire Size Use the following guideline when selecting wires or lugs to connect to terminal strips A, B,
C, D, E, F, G, H, and terminal blocks J, K. Note that the first two bullets are applicable to
terminal blocks J and K only:
• 12 AWG to 22 AWG (3.3 mm
2
to 0.3 mm
2
): Single wire termination with/without 9.53
mm (0.375”) maximum diameter ring terminals.
• 14 AWG to 22 AWG (2.1 mm
2
to 0.3 mm
2
): Multiple wire termination with 9.53 mm
(0.375”) maximum diameter ring terminals. Two ring terminals maximum per circuit.
• Suggested wiring screw tightening torques are: terminal strips A-H tighten to 4.5 in-lbs
(0.5 N-m) and terminal blocks J, K to 15 in-lb (1.7 N-m).
