NEMA L6-20R locking receptacle

NEMA L6-20R is the corresponding 20 A, 250 V locking receptacle/connector-body configuration.

Also called L6-20R NEMA L6-20R 20A 250V Twist-Lock receptacle

The NEMA code, not a rough circular resemblance, controls this identification.

Look for

Verify the L6-20R marking before mating any locking plug or extension equipment.

The useful distinction

Recognize it. Then verify it.

NEMA L6-20R is the corresponding 20 A, 250 V locking receptacle/connector-body configuration. [C220A]

Use the source-backed form or position count only for identification. Resolve ratings, protocol, direction, wiring, cable construction and exact device support from the relevant equipment and component documentation.

Before you connect

What to check

  1. Identify the exact connector family and variant from the equipment or cable documentation.
  2. Keep shape, contact count, protocol, electrical rating and device support as separate facts.
  3. Do not force, rewire or adapt a connector from this recognition record; resolve the remaining requirements first.
Trace a supported connection class →

What is not established

This field note does not approve a connection, adapter, cable assembly, rewiring scheme or fabricated part. It intentionally omits unsupported pin assignments and mechanical tolerances.
