Electrical Troubleshooting: Information to Prepare Before You Call

Good troubleshooting starts with a clear description. You do not need to diagnose the fault yourself; simply record what happened and when.

Useful details

• Which rooms, sockets or lights are affected
• Whether any breaker or RCD/RCCB has tripped
• What appliance was used just before the problem
• Any smell, heat, noise, flashing or visible damage
• Your six-digit Singapore postal code

These details help the electrician understand the likely scope of the inspection.
