Intry Verified receipt
Is the Intry Tap Conductor Calculator accurate and NEC compliant?
The provenance receipt for the Intry Tap Conductor Calculator: the exact authority its numbers derive from, the edition they are keyed to, who has final say, and how a deploy gate re-checks its numbers against their cited source.
Short answer: Every figure an Intry calculator computes comes from a locked source module, not hand-typed. 9547 automated checks re-derive and source-check the numbers against the cited NEC 240.21(B) tap rule and Table 310.16 before each deploy. This is our own deterministic gate, not a third-party audit. The per-tool receipt is public at https://www.intrysys.com/verified.
The receipt
- Calculated from
- the cited NEC 240.21(B) tap rule and Table 310.16 (NEC 2023). Reused verbatim from the locked engine, never re-written for this page.
- Checked
- Before any deploy, a deterministic test suite re-derives calculated figures from their locked source module and source-checks the numbers against what they cite, so a number is held to its real source, not just to itself. As of the current build that suite holds 9547 checks, and it gates this page too. This is our own deterministic gate, not a third-party audit.
- Runnable
- A reference engine that powers the published numbers. It is not exposed as a runnable MCP tool.
- Final say
- Your AHJ has final say. This sizes the conductor; the conditions each tap rule places on the installation still have to be met on the job.
