Intry Verified receipt
Is the Intry NEMA Plug & Receptacle Identifier accurate?
The provenance receipt for the Intry NEMA Plug & Receptacle Identifier: the exact authority its values derive from, the edition they are keyed to, who has final say, and what our automated checks hold them against.
The receipt
- Calculated from
- Hubbell Configuration Chart (Wiring Device-Kellems) · Leviton Industrial Wiring Devices Catalog · Leviton product pages, straight blade 30A / 50A / 60A · Eaton Arrow Hart colour-coded locking devices selector guide. Reused verbatim from the locked engine, never re-written for this page.
- Checked
- This tool publishes a table transcribed from its source rather than a figure it calculates. Before any release, an automated check holds that table against an independent restatement of the same source, cell by cell, and confirms the tool still refuses the cases it is required to refuse. The source is named above so you can hold the table against the document yourself. As of the current build that suite holds 28337 checks, and this page has to clear them too. This is our own deterministic gate, not a third-party audit.
- Runnable
- A reference engine behind the published numbers on this site. Runnable access is offered on the calculators exposed at the Intry MCP endpoint.
- Final say
- The rating stamped on the device face has final say. A configuration publishes here only where two independent manufacturers print it and agree. Blade dimensions live in NEMA WD 6 and are a separate layer we have not added yet.
Frequently Asked Questions
Is the Intry NEMA Plug & Receptacle Identifier accurate?
The values in this tool are TRANSCRIBED from the manufacturer configuration documents it was corroborated against, not calculated, and they are stored in a locked data module rather than hand-typed into pages. Of the 28337 automated checks that run before each release, the ones covering this tool hold every published row against a separate restatement of those documents, written independently from the documents themselves, so a row answers to a second witness rather than to itself. They also hold each cell to a known-good value and confirm the tool still refuses the cases it must refuse. This is our own deterministic gate, not a third-party audit.
