    High Ze causing headache !

    They have been out when I raised this previously (I wasn't there, Client only) and this was also before had all the help fully info above. Hopefully I may have a case now if I can use the ESQCR limits

    High Ze causing headache !

    Ok so I may have a case then..... assuming DNO have to comply with ESQCR? (not something I'm familiar with being honest) Its got to be above 60a (for size of property) going to get the Client to dig out the original paperwork from when had it installed.

    Thanks Pete How does that work with my 80amp sub-main supply though max EFLI is 0.40 for BS-88 ? My thinking for TT as an option, was if so could then put all on an RCD (time delayed for sub / house db rcbo's) and use 1667 for max ZS values. Maybe I'm missing something - has been long week!

    High Ze causing headache !

    Did raise my concerns with Client before Xmas.... DNO apparently came out straight away (I wasn't on site) said no problem all fine ! Re-checked last week still 0.51😠 I'm going to raise it myself again directly with them, making sure I'm onsite when (if) they re-visit.

    I did hear that a while back.... that they wouldn't be concerned unless above 0.8! But always hoped they wouldn't go by that

    Hi Guys Any advice/ pointers would be appreciated 😉 Have ‘pretty big’ new build house we’re wiring from scratch. New supply in from DNO is PME, but we have Ze of 0.51 😕 Are DNO obliged to keep this under 0.35? Wouldn’t be that much of an issue normally if regular size house and meter was...
