Main Switch Price in Pakistan: The Master Isolator or Breaker at the Start of House Wiring, 63 A and 100 A Ratings, Double-Pole Types and Fitting Rules
Main switch price in Pakistan runs from about PKR 1,500 for a basic double-pole isolator to over PKR 10,000 for a branded 100 A unit, and the main switch is the one control that cuts off the whole house. It sits after the meter and before the distribution board, and it must be rated for the full load. This page explains what a main switch is, the ratings, the types, indicative rates and the fitting rules. See also distribution boards, MCCB breakers and changeover switches.
What a main switch does
The main switch isolates the whole installation. In an emergency, or when work is needed on the board, you switch it off and the house is dead. It also protects the board if it includes a breaker. It must be easy to reach, clearly labelled and strong enough for the full load of the house.

Types
- Double-pole isolator. A switch that disconnects live and neutral, no protection.
- Main MCB. A breaker as a main, for smaller homes up to 63 A.
- Main MCCB. For bigger homes, shops and workshops.
- Main with RCCB. Adds earth leakage protection.

Choosing the rating
Add up the load of the whole house and add margin. Many homes use a 63 A main, and larger homes with several air conditioners use 100 A or more. The rating must also suit the incoming cable and your utility connection. A licensed electrician should calculate it.
Position and labelling
Fit it close to the meter, at a height of about 4 to 5 feet, in a dry place with space in front. Label it MAIN SWITCH and keep the area clear. Fit it in an enclosure that protects against dust and splashes.
Single and three-phase
A single-phase home uses a 2-pole main, while a three-phase supply needs a 4-pole unit. Connect the main so that live and neutral are both isolated. A wrong connection can leave the board live when switched off.
Earthing
The main earth bar must be connected to a proper earth electrode, and the earth continuity tested. Fixed wiring should be done by a licensed electrician.
Testing and use
Switch the main off and on once or twice a year to keep it free. Keep the cover on, do not use the main as a daily switch, and replace a main that gets hot. Combine with an RCCB for shock protection.
