The useful distinction
Recognize it. Then verify it.
NEMA 5-20P is the plug form paired with the NEMA 5-20 receptacle family. [C187A]
Exact source example HBL5366C: construction: Cord-mounted straight-blade male5-20P plug;2pole3wire grounding. rating: 20A125VAC. temperature: -40C without impact to75C continuous. Exact named part only. Product specification is not a specimen measurement or interoperability approval. No physical compatibility, pin map or hardware validation is established. [C187B]

Specifications and limits
| Documented identification | NEMA 5-20P plug form. [C187A] |
|---|---|
| Mechanical dimensions | No independently reviewed mechanical drawing in V36; do not use this page for fabrication, fit testing or tolerance work. |
| Engineering pinout | Source-checked engineering profile available; independent review pending. Open engineering profile → |
| Verified device list | Not included. Check exact device and accessory documentation. |
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.
