Ericson 2420-C is a connector, NEMA L14-20 configuration, and Perma-Link Industrial Grade yellow wiring device. It is a locking blade style connector with 20A and 125/250.

United States patent number 4,021,092 was assigned to today's Perma-Link plugs and connectors which are classified among the most rugged and safest wiring devices available. They incorporate many of the same features as Ericson Perma-Tite 2 and Perma-Grip™ devices and utilize a two-screw cable clamp. Perma-Link plugs and connectors are designed to provide many years of trouble-free service in the most demanding industrial and construction environments.

Our Perma-Link plugs and connectors (straight blade only) are designed so they can easily be converted to create weather-resistant connections by interchanging the internal assemblies. Insert the plug body into the connector cover, and the connector body into the plug cover. There are no extra parts to purchase.

The same rugged internal construction as our standard Perma-Link line is found in these units, and in addition, they meet UL Hospital Grade standards. Designed for reliable long life, and built to withstand exceptional abuse, these dead-front, back-wired devices save installation time, provide maximum protection, and can be used for straight blade installations in hospitals, schools, and extended care facilities. Constructed of rugged polybutylene therephthalate (PBT) and a high-tech thermoplastic elastomer (TPE), they have passed tests for ground pin retention, ground resistance, face impact, ground temperature contact, fault current, line blade retention, and abrupt removal.

• White and light “institution” gray colors identify this style which provides superior insulation. They are clearly marked “Hospital Grade” and clearly marked with a green dot to signify UL Hospital Grade. Non-conductive cord clamp to accommodate cord sizes #16/3 SJ through #12/3 SO.
• White PBT and transparent polycarbonate housing identify this type which permits visual inspection of wiring terminations without disassembly. Impact resistance, and non-conductive. The cord clamp has a removable insert to accommodate #16/3 SJTW through #12/3 SO cord sizes.
