Test all power cables prior to connection to the unit to ensure that
the conductors or cable insulation has not been damaged while
being pulled into position.
Power cables are to be connected to solderless, screw type lugs
located on the meter socket jaw assembly. Verify that the lugs sup-
plied will accommodate the power cables being used. Also verify
that the cables comply with all local electrical codes. Standard ATS
equipment, as supplied from the factory, will accommodate the wire
sizes shown in Table 2.

Carefully strip the insulation from the power cables to avoid nicking
or ringing of the conductor strands. Prepare the stripped conductor
termination end by cleaning it with a wire brush. If aluminum con-
ductors are used, apply an appropriate joint compound to the clean
conductor surface area.
