2.2.10 Output wiring (Terminal block versions)
WARNING! Before connecting output power cables, make sure input power to the panel is turned off.
27. For output wiring, crimp single-hole lugs onto one end of #22 to #10 AWG copper wires, as required by
NEC. (Work with one output wire at a time.)
28. Insulate lug barrels with UL94 V-0 rated heat-shrink tubing.
29. Clean the panel terminal and lugs with a non-abrasive, non-metallic pad.
30. If required, lightly coat antioxidant on lugs and output BATT and RTN terminals and then connect lugs to
terminals, as shown in Fig. 2-9. (NEC specifies only one lug and load at each output terminal.)
ALERT! Do not exceed torque rating. The output terminals are low electrical resistance, free floating
terminals. Note that the top output terminals may rotate slightly within the rear of the panel. This is
normal.
31. Tighten screws to no more than 8 in/lb. (.9
N•m), max. Then connect other end of output wire to load.
32. With the output loads (devices fed by this panel) disabled, re-enable breakers at primary distribution unit or
battery.
33. If applicable, check voltage and polarity at loads.
34. Record circuit assignments in accordance with operating company procedures and guidelines.
35. Enable equipment loads one at a time to verify proper operation of loads.
