    "description": "Running watts, start-up surge, duty cycle and annual energy for 30 household and off-grid appliance classes, where every figure carries the source document it was read from, the tier of that source, the date it was verified and a confidence rating. The distinguishing property is not coverage but provenance: fields that no manufacturer publishes are present and explicitly null rather than filled with an estimate, and the basis of each surge figure is labelled (nameplate locked-rotor amperage, manufacturer-stated, category envelope, or unknown) so a reader can tell a measured inrush from a rule of thumb. Compiled from manufacturer specification sheets and manuals, government efficiency filings and standards documents. Published by WattPair under CC BY 4.0.",

The manual's only electrical entries are the EN 60335-1 nameplate rating and the rated figures for the two operating modes — no transient quantity of any kind. The EU EPREL registration (2517927) was pulled in full and confirms that Regulation 626/2011 asks split units for no start-up current, and in fact for no rated input power or rated current either. For a variable-speed compressor this absence is structural."

A published EPREL washing-machine record was pulled in full on 2026-08-03 to confirm the field set rather than assume it (registration 1145659, Bosch WIW28443, used here only as a probe of the schema): it exposes energyConsPer100Cycle = 62 and no annual-consumption field of any kind. Turning 100-cycle energy into an annual figure would take a cycles-per-year assumption that no EU document supplies, so this field stays empty rather than carrying an invented one."

These manuals carry no electrical specification table at all — not even a running current. The ENERGY STAR certified room air conditioner dataset (446 units, 28 fields) has no start-up current or locked-rotor field: the field does not exist rather than being left empty. For a variable-speed compressor this absence is structural, not a gap in our searching."
