This 100 Amp, 600V max. four jaw 1-1/4" overhead meter socket with hub is formed from 16 gauge electro-galvanized steel and finished in baked grey enamel. This weatherproof hub is wedged permanently to the socket to eliminate looseness or slipping and tunnel type terminals are supplied with hexagon socket head screws that can be torqued to 120 inch pounds. Copper conductor range is 6-2 AWG and "S" series neutral is supplied as a double terminal with characteristics equal to line and load cable lugs. The jaw consists of two formed copper parts tin plated and rigidly fastened to the cable lugs. Positive pressure is maintained with the addition of a "U" shaped steelwire spring. Fifth terminals are front mounted, and may be installed in the field easily, in either the 3 or 9 o'clock positions. "S" series base is electrical grade dry press grey porcelain designed to rigidly hold the jaws in alignment, yet resist breakage. The cover assembly is held in place by a rotating latch. Additional features include Type R3 screw-on style included with "S" sockets; two no.14 to 4 "S" series lugs; and orange coloured insulated to protect the installer from accidentally shorting between the jaws and the enclosure. Dimensions are 9-1/4"H x 7-1/2"W x 3-5/8"D.
