A voltage surge investigation needs both damaged appliances and records of the network incident: a management company report, neighbours' accounts, distribution board photos, an appliance list and dates when faults were discovered.
What to prepare
- receipt, warranty card, contract, work order;
- service centre records and correspondence with the seller;
- photos and videos showing the fault;
- information about operating conditions, connection and repairs;
- documents about an accident, flooding or voltage surge, if available.
Practical conclusion
The earlier the object is preserved in its original condition and the more complete the documentation, the easier it is to establish cause and effect through expert analysis and prepare a convincing report.
