:Copper Wire
Terminate multiple power wires of
the same gauge to both sides.
Do not terminate two wires on
one side.
Do not terminate different gauge
wires to a terminal block.
Connecting the Power Wiring / Communications Cable
Best practice dictates using ring or spade terminals to terminate power wiring at the power terminal block. If ring terminals or spade clips are
not available, then:
•Do not terminate different gauge wires to the power terminal block. (Slack in the wiring may generate heat.)
•When terminating wires of the same thickness, follow the instructions demonstrated in the figures below.

•Firmly attach the wire; secure in a way to prevent external forces from being imparted on
the terminal block.
•Use an appropriately sized screwdriver for tightening the terminals.
•Do not overtighten the connections; overtightening may damage the terminals.
