Copper Pole Ground Plates

MATERIAL: CA-110 hard temper copper.

APPLICATION: For multigrounded neutral construction. Provides efficient, low resistance neutral ground at low cost. They are less expensive and easier to install than butt wrapping poles. Features four 3/16-inch nail holes, high pressure connectors for ground wire or optional braised pigtail. The bar type and the eye bolt type ground wire connectors are both designed to provide high pressure contact between the wire and the plate for a permanent low resistance connection. Both the PGPC - 80 & PGPC - 156 have two connectors. All connector parts and screws are corrosion resistant bronze or copper.
