Max Zs Values
Max Zs values to BS7671 18th Edition, fuses MCBs RCBOs & some 60947-2 MCCBs
Max Zs values for Android devices, look up the maximum permitted Zs values ( earth loop impedance ) as per BS 7671 18th edition. Max Zs values include 100% (BS 7671) and 80% (On site guide) temperature adjusted values.Select from the list of protective devices (fuses, MCBs, RCBOs) and device ratings to calculate the maximum permitted Zs value for your selected protective device. Also look up some manufacture BS EN 60947-2 Zs value PDF charts and tables, all printable from within the Max Zs values app.This Maximum Zs Values app contains Zs tables, charts and calculators all relating to the maximum permitted Zs values of BS 7671.Max Zs Values Features:+ BS 7671 18th edition Zs values+ Common BS EN MCBs, RCBOs and fuses maximum Zs calculator+ BS EN 60947-2 MCCB manufacture device charts / tables (some)+ RCD max Zs for TT earthing systems calculator+ REC max Ze (by enquiry) values+ Uo 55v and 63.5v Zs values (110v single & three phase) calculator+ Ze + R1+R2 = Zs calculator+ Zs - Ze = R1+R2 calculator+ TN & TT maximum disconnection times chartA great electrical app to have at hand when you most need it for checking or calculating the maximum permitted Zs ( earth loop Impedance) values.Max Zs Values is designed for Android tablets and phones.

Great app
Great app to have handy on site. Helps with odd Mccb sizes.
Great reference tool
Pretty good App but would like to see ABB MCCB devices added
Downloaded on Samsung twice now and app sticks on the first screen, Graphics dont align and cant open an account.
Useful app,saves thumbing through the regs books. Recommended ++++
Using a Samsung a71. Good app, shame that the app display does not align properly on the screen Post Update. Credit to the Pro Cert team. They investigated the problem and fixed it. Many thanks 5 stars
Haven't used it, just played around with it and it looks really good so far.
Works well but needed ABB MCCBs and they are not on there.
It's helpful app, but there is missing Zs values for disconnection times 1s in TT, No disconnection times for RCD's as per appendix 3, and few mistakes in wording in last section Maximum Disconnection Times like 411.3.2.5 see section 416 instead 419 and last 2 notes doesn't apply to 411.3.2.5 but 411.3.2.2. There should be explanation of symbols meaning like U0, Im, ir, Io. Have not clue what REC means. Developer means DO - Zs Values. I would expect little bit more from this app.
