Surge Suppression Systems
Connection
The AccuGuide assembly is provided in standard lengths of 5, 8, 10, 12, 15, and 20 feet. Each end of the assembly will include an
additional fi ve feet of #10, 8, 6, or 4 AWG pigtails for connection to the service and to the surge protective device (SPD). Gauge of
the pigtail is based on the SPD lug size. See chart below for units and acceptable wire ranges. An additional 10 gauge-grounding
conductor is provided with the AccuGuide assembly for use as an equipment ground.

Conduit
The AccuGuide assembly is sold without conduit. If conduit housing is required, the following conduit and fi tting sizes apply:
Equipment Performance
The ideal SPD installation locates the suppression as close to the protected bus as possible. This product was designed to address
those instances when a close installation is not possible. However, while the voltage drop experienced with an AccuGuide
assembly is signifi cantly reduced, care should be taken to keep connection lengths to a minimum.
Each end of the AccuGuide assembly is shipped with fi ve-foot pigtails. The length is offered as a worst-case need for the panel or
switchgear end (our SPD will be much less than 5 feet). We recommend cutting the pigtail to the shortest length possible.

Caution: Pigtails must be supported if pulling AccuGuide assembly through conduit. Grip only the blue coaxial cable
body when pulling the assembly through conduit. Do not pull AccuGuide assembly using the pigtails or damage
may occur.
