New distribution board installation, MCB panel upgrade, ELCB and RCCB fitting — done to IS 732 standard by our licensed electricians in Mathikere. All brands, same day.
The distribution board (DB box) is the central electrical safety device for your entire home. Every circuit in your Mathikere home — lights, sockets, AC, geyser, kitchen appliances — should have its own correctly rated MCB (miniature circuit breaker) protecting it. The whole home should also be protected by an ELCB or RCCB that trips instantly if current leaks to earth — protecting every person in the home from electrocution.
We install new DB boxes for homes undergoing house wiring, upgrade old fuse boxes to modern MCB panels, add new circuits for AC or geyser loads, and fit ELCB/RCCB protection to existing boards that currently have none. For a DB box that is tripping repeatedly, see our power trip fix and MCB repair service.
Most Mathikere homes built before 2010 have distribution boards with undersized MCBs, no ELCB protection, and circuits that combine multiple high-load appliances on a single breaker. A 2BHK that has added two ACs, a geyser, and a microwave since the board was installed is typically running at 150–200% of the board's designed capacity — and one fault can cascade through multiple unprotected circuits simultaneously.
Our team surveys your existing board, counts all circuits, measures actual load, and designs a correctly sized replacement — with spare ways for future additions. The main incoming isolator, individual circuit MCBs, and RCCB sizing are all calculated from your actual load, not guessed. Call 7411225242 for a same-day DB box assessment in Mathikere.
New installation, full upgrade, ELCB/RCCB addition and circuit expansion — every DB box service type for all Mathikere property types.
Undersized MCBs trip on normal load. Oversized MCBs allow dangerous overloads without tripping. Here is the correct sizing for standard Mathikere home circuits.
| Circuit | MCB Rating | Cable Size | Notes |
|---|---|---|---|
| Lighting circuits | 6A or 10A | 1.5mm² or 2.5mm² | One MCB per floor or zone — not whole house on one |
| General socket circuits | 16A | 2.5mm² | Separate circuit per room or zone recommended |
| Air conditioner (1–2 ton) | 20A dedicated | 4mm² | One MCB per AC unit — never shared with other loads |
| Storage geyser (2kW) | 16A dedicated | 2.5mm² | Dedicated circuit — not shared with bathroom sockets |
| Instant geyser (3–4.5kW) | 20A dedicated | 4mm² | High load — 4mm² mandatory, dedicated circuit only |
| Kitchen sockets (microwave, mixer) | 16A | 2.5mm² | Separate kitchen circuit — high intermittent loads |
| Main incoming isolator | 63A DP (2BHK) / 100A DP (3BHK+) | Per sanction load | Must match BESCOM sanctioned load for property |
| RCCB / ELCB rating | 30mA sensitivity | — | Current rating ≥ sum of all MCBs downstream — 63A or 100A |
Note — our electrician calculates the exact MCB rating for each circuit based on the actual cable size and load. Never upsize an MCB without verifying the cable can carry the increased current. Call 7411225242.
