Earthing installed and tested, and the record kept
Why — act while you have leverage
Earthing is the protection that only matters on the day something goes wrong. It is also the easiest thing to under-build, because nothing about the finished house reveals it.
What to look at
- A measured earth resistance value on paper, with the date
- Earth pit locations marked on a drawing you keep
- Separate earths where the design calls for them
- Earth resistance test record
Documents to ask for
- Earth resistance test record
How to check it yourself
Earth electrodes are installed as designed and the earth resistance is measured and recorded, not assumed. Keep the test reading with the date — it is the document an electrician needs years later, and the one nobody can reconstruct.
Where this comes from: IS 3043 — Code of Practice for Earthing; IS 732 — Code of Practice for Electrical Wiring Installations; NBC 2016 Part 8 Section 2 (indian standard or building code)
