Surge arrestors

Ask the expert – Surge arrestors

Q1: How does a surge arrestor work?

A: Put simply, it protects appliances and electronics against sudden voltage spikes caused by lightning strikes, downed power lines or faulty household wiring.

Q2: What’s the best type to have?

A: One installed in your switchboard. Think of it as your first line of defence as it stops a surge of power entering your house. The second line of defence could be to have them also installed at power points that crucial appliances are plugged into.

Q3: How is a surge arrestor different to a circuit breaker and safety switch?

A: A surge arrestor protects against voltage spikes. A circuit breaker protects against circuits getting overloaded, such as having too many appliances plugged into one power point. A safety switch protects the user against electrocution.

Q4: So I need all three then to get full protection?

A: Yes but we can save you time and money with our switchboard upgrade packages. For example, we can supply and install a combination safety-switch/circuit-breaker in your switchboard for less than $200.
