Applications
NEMA L20-20P twist-lock plugs at 347/600V 3-phase are used extensively in Canadian and international industrial facilities, commercial buildings, and data centers where high-voltage 3-phase distribution at the L20 locking standard is employed. The 347/600V Y configuration is the standard Canadian high-voltage distribution voltage and is common in industrial motor loads, HVAC equipment, large lighting circuits, and heavy commercial machinery. The Hubbell Twist-Lock series is a well-established locking plug and receptacle standard used across manufacturing floors, utility distribution panels, and portable equipment connections where a secure, pull-resistant connection is required.
