POWERTITE® 30 A pin and sleeve plug made of aluminium with epoxy powder coat. 6 inch length, 3.13 inch outer diameter. 1.86 inch wire recess diameter. Pressure wire terminals. Neoprene bushing compressed by cable collar prevents entrance of water. Bushing is highly resistant to hydrocarbon deterioration and is self-extinguishing. Locking screw and slot prevents plug cable collar from backing off. Contacts exert constant pressure along entire contact surface and provide electrical continuity. Suitable for use from -40 to 107 °C. Insulating blocks provide greatest dielectric and mechanical strength and lowest arc tracking. Positive polarization. Designed to supply power to portable or fixed electrical equipment such as motor generator units, welders, pumps, compressors, cellular relay stations and similar apparatus.
