Checks

Every check Wiring Lab runs, and the standard behind it

Wiring Lab runs 89 checks on the project, each with a stable code and a reference to the standard behind it. Choose the country of the site: you get the electrical profile the software proposes and the full list of checks you will see in the Validation window.

No check matches your search.

The standard cited. Where a standard is named, the check comes from it and the message quotes it in full, with the clause. The entries WL-CONVENTIONS and WL-INTEGRITY are not standards: they are the model-consistency checks — a cable missing an end, two identical designations, a conductor size written in mm instead of mm². We run them because no standard covers them, and because an inconsistent design cannot even be checked.

Why the electrical standard changes and the others do not. The cabling and documentation standards Wiring Lab cites — TIA-606, TIA-607, TIA-569, EN 50174-2, the AVIXA ones — are international or regional, and the check is identical everywhere. Electrical installation standards, on the other hand, are national: there the reference changes, and with two profiles (NEC and CEI 64-8 / IEC 60364) so do the thresholds.

Two checks apply in one country only: the minimum conduit diameter (Italy) and the separation between loudspeaker lines and other signals in the same conduit (United States, required by AVIXA). They appear in the list only when you choose that country.

Wiring Lab helps you check a design against the requirements of the standards it cites, and reports the reference behind every check. It is not a certification body and it does not replace verification by a qualified professional.
