MCB, Distribution Board & Changeover Installation in Mohali
The distribution board is the safety heart of a house. Sized and wired correctly it isolates a fault in one circuit; done badly it is the reason a whole floor goes dark or, worse, a wire heats up without the MCB ever tripping.
What this covers
We install new DBs and rebuild old ones: incoming isolator, correctly rated MCBs per circuit, RCCB for shock protection, neat bus-bar and neutral-link work, and every way labelled so anyone can find the right switch in the dark. Ratings are chosen from the real connected load, not by habit — an oversized MCB protects nothing, and an undersized one trips all evening.
We also fit manual and automatic changeover switches for inverters and generators, and separate the backup circuits so your lights, fans and Wi-Fi stay on while heavy loads stay on mains.

FAQs about mcb, db & changeover installation in Mohali
Why does my MCB keep tripping?
Usually one of three things: the circuit is genuinely overloaded, there is an earth leakage from a faulty appliance or damp wiring, or there is a short at a point. We trace it with a meter and fix the cause rather than just resetting or replacing the MCB with a bigger one — which is dangerous.
Is an RCCB really necessary?
Yes. An MCB protects wiring from overload; an RCCB protects people from shock by cutting power the moment current leaks to earth. For any house with a geyser, washing machine or small children it is essential.
