The useful distinction
Recognize it. Then verify it.
NEMA L5-20R is the corresponding 20 A, 125 V locking receptacle configuration documented as 2-pole, 3-wire grounding. [C218A]

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