Intry Verified receipt
Is the Intry Outdoor HVAC GFCI Requirement (NEC 210.8(F)) accurate and NEC compliant?
The provenance receipt for the Intry Outdoor HVAC GFCI Requirement (NEC 210.8(F)): 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, rebuilt from their cited source.
Short answer: Every figure an Intry calculator computes comes from a locked source module, not hand-typed. 29291 automated checks re-derive and source-check the numbers against the cited NEC section together with your state's own amendment to it 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
- NEC 2023 and NEC 2020, 210.8(F), read from the printed book · TIA 20-19 and TIA 23-3, the lineage of the exception itself · Each state's own amendment to 210.8(F), where we hold it · Each state's own current-code listing, for what is in force today · The compiled adoption dataset, published as the weaker source (NEC 2023). Reused verbatim from the locked engine, never re-written for this page.
- Checked
- Before any release, an automated check rebuilds the calculated figures from the locked engine that produces them and holds each one against the source it cites, so a number answers to its source and not merely to itself. As of the current build that suite holds 29291 checks, and this page has to clear them too. This is our own deterministic gate, not a third-party audit.
- Runnable
- Exposed at the Intry MCP endpoint. An AI assistant can run this calculator, and before each release an automated check confirms the answer it returns is identical to the one the website's own engine produces.
- Final say
- This answer holds only for the jurisdictions whose amendments we have read from their own primary documents. Everywhere else the tool refuses, and your AHJ has the final say in every case.
