Why Won’t My Circuit Breaker Stay On?

Discover how circuit breakers function as essential automatic electrical switches, providing critical protection and control for your electrical systems. Learn more in our comprehensive guide!

First up – What Even Is a Circuit Breaker?

A circuit breaker is like your electrical system’s bodyguard. It’s an automatic switch that cuts off power the moment there’s an overload or short circuit. This protects your wiring, prevents fires, and stops appliances from getting fried. Think of it as a giant ON/OFF switch that’s always on alert.

So, Why Won’t My Circuit Breaker Stay On?

When there’s a fault or the system’s overloaded, your breaker will trip—basically shutting off the power to prevent damage. Unlike old-school fuses that need replacing, a tripped breaker just needs to be reset.

Here’s how:

  1. Flip the switch from the tripped position to fully OFF.
  2. Then flick it back to ON.

Simple. But what if it won’t stay on? That means the issue’s still there.

Here’s What You Can Do:

  1. Unplug Everything First – Go through the house and unplug all your appliances. Yes, everything—kettle, toaster, TV, you name it.
  2. Try Resetting Again – Once you’re sure everything’s unplugged, try resetting the breaker. If it holds, start plugging things back in one at a time to figure out what’s causing the trip.
  3. Still Won’t Stay On? – Then there’s probably a bigger electrical fault or the breaker itself is cactus (faulty). Time to call in the pros.

What About Fuse Switches? Why Won’t They Stay On?

Still dealing with a fuse box? No worries, plenty of Aussie homes still have them. If your fuse switch keeps flicking off and won’t stay on, here are a few common reasons:
  • Overloaded circuits
  • Short circuits
  • Loose wiring
  • Worn-out fuse components
Let’s walk through how to safely sort it out.

How to Fix a Blown Fuse – Step by Step

1. Switch Off All Appliances

Find out where the blackout is. Test each room by flipping lights and checking power points.

2. Turn Off the Main Power

Always shut off the main switch before touching anything in the fuse box. Safety first!

3. Find the Fuse Box

Usually in the garage, laundry, or outside on the wall. Older homes tend to have the older-style fuse boxes.

4. Spot the Blown Fuse

Look for a fuse with melted wire or discoloured glass. That’s your culprit.

5. Replace the Fuse

Head to your local electrical or hardware store and grab a new one with the same amperage. Unscrew the blown fuse and screw the new one in carefully.

6. Power It Back Up

Turn your main switch back on and test the lights and appliances. If everything’s working, you’re good to go.

Wrapping It Up

If your circuit breaker or fuse won’t stay on, it’s usually a sign that something’s not right—either an overloaded circuit, dodgy appliance, or old wiring. Try the simple fixes above, but if it keeps happening, don’t mess around. Get one of our licensed sparkies in to take a proper look. We’ll check the system, fix the fault, and make sure your home is safe and running like it should.
