Really Good app but buggy

So there's problems with the single cable calculator first off it keeps skipping to the next selection when your press one criteria you want to change but even when you've worked at it for ages the only cable size it comes out with is greater than 400mm for a 32a single phase circuit going 15m. There's times when this app could be really useful sadly i can't trust it so I have to resort back to the bs7671 and my battered on site guide
On the plus side the app offers great advice on gland and cleat selection for swa cable I would like to see this extended to cover SY glands and MICC glands and I would like to see more selection of cable types in the single cable calculator and even maybe a section covering voltage drop on low voltage cat 5 and cat 6 cable and different wiring options for RJ11 and RJ45 plugs. Another section that could be useful would be a section covering bs numbers for main switches switched fuses rcd rcbo mcb rewireable fuses cartridge fuses etc.

Great app


Very good app, handy onsite.
Would be good to be able to zoom in on the pictures.
Also the cpc calculator from the line conductor has a mistake at 120mm it gives cpc of 6mm!

Very useful


It requires a few polishes, great potential here , it desperately needs an update but It does the job great for what I need it for:
MAX Zs values, and quick Reference to charts. Thanks developer.
