The useful distinction
Recognize it. Then verify it.
NEMA TT-30P is a 125 V grounding plug designation used for recreational-vehicle service; its 30 A rating does not make it a 14-30P substitute. [C281A]
Exact source example 830-E: construction: Angled2pole3wire grounding plug; current part replaces830-T. rating: 30 A125 V. Exact manufacturer part; construction, role and regional rating remain scoped. No physical compatibility, pin map or hardware validation is established. [C281B]
Source-scoped identification facts
Each value retains its exact example, role and measurement axis. Facts from different parts must not be combined into an invented component.

Specifications and limits
| Documented identification | 3-position/contact/conductor recognition fact in the cited implementation. [C281A] |
|---|---|
| Mechanical dimensions | No independently reviewed mechanical drawing in V47; do not use this page for fabrication, fit testing, receptacle selection 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 connector name and position/contact count only for identification. Resolve circuit or system requirements, wiring, grounding, protocol, ratings, device support and installation requirements from the exact equipment and component documentation.
Before you connect
What to check
- Identify the exact connector family and variant from equipment, component or cable documentation.
- Keep physical form, contact count, electrical rating, wiring and device support as separate facts.
- Do not force, rewire, adapt or energize a connector from this recognition record; resolve the remaining requirements with qualified documentation first.
What is not established
This field note does not approve a connection, adapter, cable assembly, rewiring scheme, energized test, installation or fabricated part. It intentionally omits unsupported wiring assignments and mechanical tolerances.
Your next step
