Pro's 1. I like the layout of the app, it is formatted in a logical order. 2. Easy to use, especially onsite for a quick check. 3. App support are very helpful, I had a problem, and they emailed me at various times of the day and evening. 4. Like the option to print out a document with the design and circuit data. Cons 1. Can't see an option to save circuit details. 2. Text overlapped on results sheet. However, easily sorted by reducing display font size (support team solution to this).

Nice easy to use calculator, would be nice if you could add a separate CPC for distribution circuits but not a dealbreaker.

Been using it for about a month now, and it's been brilliant Best cable calc I've found by far

Asks for too much data before calculating. It's very difficult to calculate the initial cable size, as it asks for way too much data. For example, it asks for Ze (Impedance) and Protective device rate, when it is not needed. For example, I simply run cable from transformer to the building electrical panel. If you simply need to calculate size of the cable based on kW or Amp total, all these data is not necessary and not needed. The other application from Ettoire Group is much better.
