Wire Leads Twenty-four inch leads are provided. The wire leads are 10 AWG stranded
copper wire. See Table 3 for wire color.
Branch Circuit Overcurrent
Protection and Disconnect Means
A branch circuit Overcurrent Protection Device (OCPD) either in the form of
a circuit breaker or fuse, must be provided for the PM2X device. The branch
circuit OCPD should either provide or include a disconnecting means.
Since the current drawn by the PM2X device during standby operation is
negligible, the PM2X device can be connected to a dedicated, separate
branch circuit or connected to a suitable existing branch circuit.
When connected to a separate, dedicated branch circuit, the OCPD setting
must be selected to protect the conductors feeding the PM2X device per
applicable state and local building codes.
During surge suppression, current will flow through the PM2X device. The
branch circuit OCPD must pass this surge current without tripping for the
PM2X device to function properly.
For further information concerning coordination of the OCPD with the PM2X
device, refer to the Caution statement “Loss of Branch Circuit Power/Loss of
Surge Suppression” page 4.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Use conductors rated for the Overcurrent Protection Device (OCPD) per
applicable codes.
• Use conductors rated for the application per applicable codes.
Failure to follow these instructions will result in death or serious injury.
