Leviton''s ECT single-pole cam-type connectors are being used by the U.S. Navy to supply dockside power at naval bases. Non-switched (22R26) and switched (22R28) series Latching Ball Nose Panel Receptacles are now listed in the new United Facilities Guide Specification (UFGS) 16145, which applies to all electrical substations installed on new or refurbished Navy piers. The UFGS is a joint effort of Army, Navy, Coast Guard, National Guard, Marines, and Air Force.
Tests conducted at the request of the chief waterfront specialist in charge of all U.S. Naval facilities demonstrated that Leviton''s single-pole cam-latching ball nose connector had only minimal arcing and sustained no damage when connected or disconnected under load. In comparison, the multipin connector previously used by the Navy was heavily damaged and exhibited a potential danger when disconnected under load. The load test was one of many conducted to determine which connector would best fit the needs of the Navy. While none of the connectors were designed to intentionally make or break contact under load, the ability to do so clearly provides a safer operating environment.
Leviton developed the 22R26 and 22R28 series with the Navy to meet all UFGS specifications. The devices feature an exclusive15 deg angled panel mount design (female), with protective cap, microswitch (22R28), unique UV-resistant SantopreneTM thermoplastic rubber insulation, and threaded stud termination. The 22R26 and 22R28 receptacles are rated for 600 V and 690 A continuous-duty operation at 60 Hz.
Naval bases and shipyards use Leviton''s positive cam-type latching connectors and receptacles in supplying 480 Vac 3-phase power to ships at dockside. Completely insulated and vibration resistant, the connectors will not loosen even during intense use. Since their male contacts provide 40% more surface contact with female plugs than competitive products, Leviton connectors provide substantially greater conductivity and burnout protection. The Navy base at Norfolk, VA, has already converted to Leviton panel and inline male and female connectors. The Naval facility in San Diego, CA, has committed to a total conversion to Leviton connectors, and the base at Mayport, FL, has already started the conversion.
