What’s the Difference Between a Circuit Breaker and a Safety Switch?
Circuit Breaker vs Safety Switch? If you own a home or business in Perth, you’ve probably heard of both circuit breakers and safety switches. But do you know the difference between the two? Many WA homeowners assume they do the same job, but that’s not quite right. In fact, both play very different roles when it comes to protecting your home, your appliances, and most importantly—your family.
In this article, we’ll break down the key differences between a circuit breaker vs safety switch, why you need both, and how to check your switchboard to make sure your home is properly protected.
What Does a Circuit Breaker Do?
A circuit breaker protects your home’s wiring and appliances from overloading or short circuits. It will trip when too many appliances are running at once, preventing overheating and fire risks.
What Does a Safety Switch Do?
A safety switch protects people from electric shock by detecting current leakage and shutting off power within milliseconds.
