Panel with 5 GMTs
ALERT! Only use components and crimping tools
approved by agencies or certifying bodies
recognized in your country or region such as
Underwriter’s Laboratories (UL), TUV, etc.
6. Use a listed (approved) crimping tool to attach a
listed (approved), dual-hole compression lug onto
suitable ground wire. (The size of the ground
depends on the input interruption device.)
7. If required, lightly coat an antioxidant on the lug
and grounding surface on the rear of the panel.
8. Connect using

-20 hex nuts and flat washers
provided, as shown in Figure 4.
9. Tighten the bolt to 25 in-lb. (2.83 N
•
m), max.
WARNING! Before connecting input power cables,
make sure input power to panel is turned off.
10. Make sure the input power is off (open breaker,
dummy fuse or open fuse holder at primary power
distribution unit or battery) before connecting this
panel’s input cables to the PDU or battery.
11. For input wiring — wiring used as inputs to this
load center — crimp dual-hole compression
lugs onto #1-AWG to 750-MCM copper wires.
The choice of input wiring depends on the
following criteria:
•
The input interrupt device rating affects the
size of the input wiring.
•
Ambient operating temperature affects the
type of input wire insulation. For further
information consult the National
Electrical Code (NEC).
