Calculator · RCD / earth leakage
Estimate cumulative leakage from compressors, dehumidifiers, portable AC, heaters, pumps and long wet leads before stacking everything behind one RCD.
Use it when drying or cooling equipment trips randomly or when several items share one RCD/RCBO.
Calculator · MCB curve / motor start
Estimate whether fan or compressor starting current is likely to be harsh for a B, C or D curve MCB.
For compressor/fan start trips and generator-fed temporary power.
AI tool · AI / panel photo
Upload a board photo and create a draft circuit map, breaker list, RCD group notes and temporary HVAC suitability questions.
A triage tool. It does not replace inspection, testing or opening a panel by a competent person.
AI tool · AI / thermal-style
Use a normal phone photo for a thermal-style risk overlay based on visible clues, or upload true thermal imagery when available.
Normal cameras cannot measure temperature. This flags visual risk clues and creates a pseudo-thermal check map.
Calculator · panel schedule / circuit schedule
Create a printable schedule for boards feeding temporary heaters, dehumidifiers, fans, drying kit or AC.
Use after a board photo, site walk-round or temporary DB layout.
