Good trade decisions begin with a clear understanding of the problem, the result you need and the questions worth asking before work starts.
Make the situation safe
Keep people away from burning smells, damaged electrical equipment and water near electrics. Isolate equipment only when the controls are safe to reach.
Record useful information
Note when the problem started, what changed beforehand and which rooms, circuits or equipment are affected.
Call the correct specialist
Electrical danger, failed cooling and refrigeration temperature loss each need the appropriate specialist response.
Keep photographs, quotations and important decisions together. A simple written record helps everyone work from the same scope.
When to seek specialist advice
If the issue affects electrical safety, cooling performance, refrigeration temperatures or solar equipment, arrange an assessment from the appropriate specialist rather than relying on a temporary fix.
