Having something trip the power in your home can be an extremely frustrating occurrence – especially if you’re in the middle of a task, and particularly if you don’t know what has caused it. Often, the problem may be simpler than you think. There are a few reasons why your power might have tripped. Even better, there are simple steps to follow to fix the problem quickly and easily, allowing you to get on with your day.
Causes of a Power Trip
Essentially, a power trip occurs when the electrical system in your home is compromised in some way. The trip is a safety mechanism, meaning your circuit breakers will ‘trip the switch’ and automatically shut down power to one or several systems, making sure the problem cannot become anything more serious. This can happen for a number of reasons.
Overloaded Circuit
The most common cause of a power trip is an overloaded circuit. If you have too many devices or appliances running simultaneously, the circuit can end up drawing more electrical load than it is equipped to handle. It heats up, the circuit breaker senses this, and the power trips before the circuit can heat to a dangerous level. Example: Using multiple space heaters, kitchen appliances, or high-power devices all at once can easily overload a circuit.
Short Circuit
A short circuit occurs when a wiring problem in a device or appliance causes an unexpected flow of electricity when connected to your main system. This can also happen if two opposing wires accidentally touch, causing a surge of electricity that will trip the circuit breaker. This type of issue can lead to significant electrical hazards if not addressed promptly. Example: Damaged wires, pests chewing on electrical cords, or water exposure can lead to short circuits.
Earth Leakage Fault
An earth leakage fault is a type of short circuit, and it happens when current flowing through the electrical system finds an alternative path other than the active or neutral conductors. These are more dangerous, especially in wet areas like bathrooms or kitchens, where moisture can carry the electricity and cause electric shocks. As with a short circuit, this increase in electricity flow causes the circuit to heat up, triggering a trip to prevent further damage. Example: A leaky washing machine or faulty appliance could create an earth leakage fault.
What to Do About a Power Trip
In the case of a short circuit or a ground fault, it is advisable to promptly seek professional advice to resolve the problem safely. If you live in the south-east, you may want to call your electrician (or your local area) and have a specialist assess the situation. However, in the case of an overloaded circuit, you can often resolve the issue yourself by following these simple steps.
Before a Fault Occurs: Preparation
It’s useful to know where your electrical board is located, as well as keeping a handheld torch in case of a blackout. Having these items ready can make it easier to troubleshoot the issue quickly and safely.
Step-by-Step Troubleshooting
- Turn Appliances Off: Ensure that any appliances connected to the affected system are turned off. This reduces the strain on the circuit and helps to prevent further trips.
- Master Switch: Go to your power board and first turn off the master switch. This ensures that you cannot get hurt while fixing the problem.
- Safety Switch: Ensure you have an RCD (Residual Current Device) safety switch installed. Use this switch to check the safety of your appliances and the overall electrical system.
- Test: Once you’ve flipped the relevant switch back to the ‘on’ position, test whether the circuit is working again. If it isn’t, or if it immediately trips again, the problem may be more severe than just an overloaded circuit, and you’ll need to call in a professional.
Preventative Measures to Avoid Future Power Trips
To avoid facing frequent power trips in the future, consider the following preventative tips:
- Distribute Electrical Load: Avoid plugging too many high-power appliances into the same circuit. Use power strips or separate circuits to balance the load.
- Surge Protectors: Invest in surge protectors to safeguard your appliances against unexpected electrical surges.
- Routine Inspections: Have your electrical system inspected regularly to catch early signs of wear, damage, or outdated wiring that could lead to trips.
- Upgrade Wiring: If your home has older wiring, consider having it upgraded to prevent frequent trips or fire hazards.
When to Call an Electrician
While many power trips can be fixed by following the steps above, there are situations when professional help is necessary. If you notice any of the following, it’s time to call an electrician:
- If the circuit trips immediately after you reset it.
- If you smell burning, see smoke, or hear buzzing noises near your electrical system.
- If you notice a significant electrical fault that you cannot diagnose or fix yourself.
- If the wiring in your home is old or has been exposed to water damage.
These warning signs may indicate a much larger electrical issue that could pose a serious safety risk to your home and family.
Regional Considerations
If you live in coastal areas, like Brighton, keep in mind that salt air can cause corrosion of electrical systems, which can increase the likelihood of power trips. Regular maintenance checks are essential to ensure the integrity of your wiring and circuit breakers.
Conclusion
While it can be frustrating when the power trips in your home, understanding the common causes and how to resolve them can save you time, money, and stress. Always follow safety precautions, and if in doubt, don’t hesitate to call a licensed professional to ensure your home’s electrical system is safe and functioning properly.
