Circuit Breaker / DB Services
DB Box Rewiring in Singapore
A DB rewire starts from $300 at SG QuickFix. The wiring inside the distribution board is redone neatly: connections remade, overheated or undersized links replaced, and every circuit labelled, while the existing enclosure and incoming supply stay. It suits boards that have been modified over the years or show signs of heat, and takes about three to five hours.

Task guide
When this may be needed
- The inside of the DB box is a tangle of added wires.
- Wires or terminals show discolouration from heat.
- Nobody knows which breaker controls which circuit.
- Previous additions were connected without proper terminals.
- The board buzzes or smells warm.
What the team does
The technician switches off the main supply and documents each circuit before disconnecting anything. The internal wiring is removed and redone with correct cable sizes, proper terminals and neat routing, and heat-damaged links and busbars are replaced. Each circuit is reconnected to its breaker, tested and labelled. The board is closed, power is restored circuit by circuit, and every circuit is checked.
Included in this price
