Load worked out before the wiring, not after
Why — act while you have leverage
Interior work adds hobs, ovens, geysers, ACs and a lot of lighting to wiring that was sized for none of them. The failure shows up as tripping months later, and the fix is the wall you have just finished.
What to look at
- An appliance list made before the wiring is designed
- Cable sizes stated per circuit, not "as usual"
- Dedicated circuits for the heavy loads
How to check it yourself
List every appliance the finished room will hold and have the circuits and cable sizes worked out for that load — not for what was there before. Kitchens and utility areas are where this is most often under-provided. Separate circuits go where the design calls for them.
Where this comes from: IS 732 — Code of Practice for Electrical Wiring Installations; NBC 2016 Part 8 Section 2 (load estimation, DB sizing) (indian standard or building code)
