What are the most common home electrical problems in Castle Hill?

Family homes in Castle Hill rely on a number of electrical appliances and features for everyday life, which makes occasional electrical faults unavoidable. The most common of these include:

  • Electrical surges
  • Faulty light switches
  • Dips or sags in power
  • Tripping circuit breakers
  • An overloaded circuit
  • Excessive load on home wiring
  • Uneven lighting or bulbs that burn out too quickly
  • unprotected wire cabling

Why does my safety switch keep tripping?

Safety switches are designed to protect people from electric shocks. If yours is continually tripping, it’s an indication of a problem somewhere along the line. The most common causes of frequently tripping safety switches are faulty appliances like microwaves, kettles, fridges, and air conditioners.

Damaged wiring, rain damage and short-term electrical faults can also cause it to switch. If you can’t find the source of the problem, give our expert electricians at O’Brien Electrical Castle Hill a call on (02) 9894 4843 and we’ll help you fix the problem.
