Note 1: The recommended ring lug connector listing consists of wire size – screw size
format. The wire sizes are in AWG or mm
for the ring lug centers are: #10, #12, 1/4", 5/16", and 1/2". For metric wire sizes,
bolt sizes for the ring lug centers are: 6 = 6M, 8 = 8M, 10 = 10M.
Note 2: Prepackaged square washer is to be used when the bare wire is directly connected to
terminal without using crimp contact (such as ring lug connector).
Note 3: [N] terminal for braking unit is common to [N] terminal of power lines.
TIP: AWG = American Wire Gauge. Smaller numbers represent increasing wire thickness.
kcmil = 1,000 circular mils, a measure of wire cross-sectional area
