The electrical safety layer is named, not assumed
Why — act while you have leverage
Quotations routinely list premium wire and switch brands and say nothing about the devices that stop a shock or a fire. The expensive-looking part of the electrical scope is not the part that protects anybody.
What to look at
- Earthing described, with its type
- ELCB or RCCB named
- MCB ratings per circuit, not a single figure for the house
- A distribution board with a way count
How to check it yourself
Find four things in the electrical scope: earthing, an ELCB or RCCB, MCBs with a rating per circuit, and the distribution board. Brands of wire and switches are not a substitute for any of them. Where the house has three-phase supply, the earthing requirement is larger, not smaller.
Where this comes from: IS 732 - Code of Practice for Electrical Wiring Installations; IS 3043 for earthing (indian standard or building code)
