Why Your Breaker Keeps Tripping & What to Do Safely

Re-setting a breaker is easy — but figuring out why it trips is the key to avoiding recurring problems or hazards. We show you how to analyse common causes and when to call a licensed electrician.

Common Symptoms
Breaker trips within seconds of turning on a device, trips during heavy load, trips randomly with no obvious cause.
Possible Causes
Overloaded circuit, faulty appliance, ground fault, short circuit, old or damaged wiring.
What You Can Do
Identify what’s on the circuit, reduce load, unplug suspect devices, monitor if trips stop — then plan for inspection.

In homes across Burlington, Hamilton and the Halton region, repeated breaker trips often signal hidden issues — not simply “too many things plugged in.” Before relying on repeated resets, use this guide to troubleshoot safely and decide when a professional call is required.

Step-by-Step Troubleshooting Guide

  • 1. Identify the circuit: Check the breaker label and what’s connected (lights, outlets, HVAC, etc.). Create a list of devices on that circuit.
  • 2. Unplug all devices: Reset the breaker with nothing plugged in. If it holds, plug in devices one at a time until it trips — the last device may be the issue.
  • 3. Watch for heavy loads: Does it trip only when the fridge, washer, or EV charger runs? Consider separate circuit or upgrade.
  • 4. Inspect for smell or burn marks: Discoloured outlets, warm plates or burning smell mean immediate professional inspection is needed.
  • 5. When you should call a pro: Breaker trips with nothing plugged in, breaker resets but trips immediately, aluminium wiring, panel older than 20-25 years — contact a licensed electrician.

Frequently Asked Question

Q: Is it safe to just keep resetting the breaker when it trips?
A: Repeated resets without investigating the cause are not safe. It can mask wiring problems, overloads or component failure which may lead to fire risk or damage to appliances. Resetting occasionally after unplugging devices is fine — but persistent trips require inspection.

Branded Tip: Keep a simple **breaker-log notebook or photo list** next to the panel. Note when a breaker trips, what you were doing and devices in use. This helps your electrician diagnose faster if you need one and may locate patterns sooner.
