Electrical installations and wiring seem to depreciate with both age and usage. They need to be inspected and tested are regular intervals in order to see whether they are in safe working condition. You cannot see electricity and both wires and cables are usually hidden inside consumer units and walls and sometimes cupboards. Therefore, being out of sight, we tend to forget to check the condition of our electrical installation for either wear or tear or damage. Old and faulty wiring happens to be the main cause of electrical fires in the home and also increase the likelihood of other electrical hazards taking place.
