The ‘Electrical Reference’ app in still in development. This is the ‘toolbox’ app that the Conduit Calc is part of.
When it is finished it will include many different items of reference material; for example Max. Zs values, Installation Methods and tools such as the Conduit Calc, a Cable Size Calc, Power Triangles.
I am quite excited about this one as I personally will get great benefit from it and also think many UK based Electricians will too.
