Pass & Seymour L1620-R – Frequently Asked Questions

1) Is the Pass & Seymour L1620R UL listed for a commercial inspection?
It is cULus Listed, and the NEMA L16-20R configuration plus the third-party listing mark appear on the face of each unit, which is what an inspector looks for when verifying the device matches the circuit.
2) I need a 20A 125V outlet for office or commercial receptacles, not 480V. Is this the right part?
No. The L1620R is a 480V 3-phase locking device for industrial equipment, not a general-purpose outlet. For 20A 125V NEMA 5-20R duplex work, look at the Leviton 16352-1PW commercial grade straight blade duplex or the Leviton Decora Plus 16342, and for heavy-duty 20A 125V the Bryant 5362B.
3) What if my 480V equipment draws more than 20 amps, or the area is classified hazardous?
The L1620R tops out at 20A, so a larger load needs a bigger device. For higher current locking service there is the Eaton industrial locking receptacle rated 50A at 600V/250V AC/DC. In a classified area a general-purpose nylon device is not acceptable; use a factory-sealed or explosionproof assembly such as the Appleton FSQC Series interlocked explosionproof receptacle.
4) Can I back-wire the Pass & Seymour L1620R, or do I have to side-wire it?
Both work. The L1620R takes side-wire terminals or external screw pressure-plate back wiring, so you can land conductors whichever way the box depth and conduit entry allow.
5) Is this 480V receptacle suitable for a plant where plugs get pulled constantly?
Contact retention is the point of the design. The L1620R uses 0.032 inch thick solid brass triple-wipe contacts for grip through repeated plug cycles, a single-piece solid brass mounting strap instead of riveted strap assemblies, and an ultrasonically welded impact-resistant nylon face and body. That combination is aimed at production lines, motor connections, and workshop power drops.
6) What color is the Pass & Seymour L1620R, and will it match other industrial devices on the wall?
Black with a matte finish, which is the usual look for industrial locking devices rather than the white and gray used on commercial straight-blade outlets. Ordering code is L1620-R.
7) Where is the Pass & Seymour L1620R made? I have domestic sourcing paperwork to file.
Country of origin is Mexico. The manufacturer spec sheet is published for the device if you need it attached to a submittal package.
