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.

Hi Richard, we have taken your comments on board and have updated the Max Zs Values (3.1.5) app to suit, thank you for your feedback. Re your comment on "disconnection times for RCD's as per appendix 3" this is not related to max Zs values, you can find RCD disconnection times tables in our Electrical Tools & Reference App.
