CABLE SIZE CALCULATOR BS 7671
BS7671 CABLE SIZE CALCULATOR
This Application is designed to assistthe user, whilst using The IEE regs (BS7671)to determin correct cable size.
This Application eliminates the need to rememberany complicated formulas.Will work through a calculation as laid outin Appendix 4 of BS7671 IEE Regs.
Reference to Regs is still required, to entercertain values such as Max Zs for protective device,Volt drop for cable type / size etc.
This Application is a great tool for studentswho need to learn the correct way to calculatecorrect cable size for a new circuit / installation.
For Copper Cables up to 1000mm
Calculates Volt Drop,Earth fault Loop Impedance (Zs),Minimum required CPC Size,Design Current / Power,R1 + R2 etc.
All required formulas for completinga cable calculation.
Application runs through a cable calc,step by step as laid out in Appendix 4 of BS 7671.There is a Help File in each section,to assist you with selecting correctcorrection factors etc.Will guide you to the correct Tables / charts etc in BS7671,Making refering to regs quick and easy!
This makes this app ideal for studentscurrently taking City and Guilds 2382,2391 & 2330.
Also an excellent tool for Domestic,Commercial and industrial Electricians.
Works for all cable sizes, Installation Methods etc.
Please rate this App if you like it.

Not sure as to the point of this app, it requires the inputting of all the max Zs values for the protective device, the mA/m values for the cable etc. I thought the idea would be to save you the hassle of getting all that data together but instead it just acts a calculator? Somebody has gone to a lot of trouble for nothing?

You have to trawl through the various tables in the regs to input the data so you have already carried out the cable sizing. It gives you the minimum earth size but there is a quicker method of finding that too! Granted its more crude but it works. It would be better if it gave you a good estimate of csa based on length, max circuit power, and install method. Plus a percentage for future expansion.
