DB Box Troubleshooting in Singapore
Distribution board troubleshooting starts from $100 at SG QuickFix. When breakers trip and won't reset, the DB box hums or smells warm, or circuits are dead with no breaker tripped, the board's breakers, connections and busbar are checked to find the cause. Most checks take 30 to 60 minutes, and the repair is priced before work.

Task guide
When this may be needed
- A breaker trips and won't reset.

- A circuit is dead but no breaker has tripped.
- The RCCB's test button doesn't trip it.
- The main switch trips without any obvious cause.
What the team does
The technician checks whether the problem is the board or a circuit: a circuit fault follows the circuit, while a board fault stays with the breaker or busbar. Each breaker is tested, connections are checked for looseness and heat damage, and the RCCB is tested. Loose connections are tightened on the spot. Failed breakers or damaged parts are identified and priced.

FAQs
Either the fault on the circuit is still there, such as a faulty appliance or damaged wiring, or the breaker itself has failed. Troubleshooting finds which.
A faint hum can be normal, but buzzing, warmth or a burning smell point to a loose connection or failing breaker and should be checked promptly.
Press its test button. It should trip immediately. If it doesn't, it is faulty and should be replaced by a licensed electrical worker.
