Electrical systems are a fundamental part of our homes, yet there are many misconceptions that can lead to unsafe practices or unnecessary expenses. Here, we address common misconceptions to help you better understand your home’s electrical system.
1. If an appliance is working, it must be safe.
Fact: Just because an appliance is working doesn’t mean it’s safe to use. Faulty wiring, damaged plugs, or excessive current leakage can pose serious risks, even if the device seems to function normally. Always inspect your appliances for damage and use a Residual Current Device (RCD) for added protection.
2. DIY electrical work is safe as long as you’re careful.
Fact: Electrical work should always be carried out by a qualified professional. DIY electrical work is not only dangerous but can also fail to comply with legal safety standards, putting your home and family at risk. Improper installations can lead to fires, electric shocks, or other hazards.
3. Circuit breakers and fuses protect against electric shocks.
Fact: Circuit breakers and fuses protect against overcurrent and short circuits, not electric shocks. They prevent your wiring from overheating, but they won’t stop a person from getting a shock. RCDs (Residual Current Devices) are specifically designed to protect against electric shocks and should be part of your consumer unit.
4. Modern homes don’t need electrical inspections.
Fact: Electrical systems degrade over time, regardless of the age of the property. Even modern homes should have regular Electrical Installation Condition Reports (EICRs) to ensure the system remains safe and complies with regulations.
5. It’s okay to use extension leads permanently.
Fact: Extension leads are designed for temporary use, not as a permanent solution. Overloading or daisy-chaining (connecting multiple extension leads) can lead to overheating and increase the risk of fire. If you need additional sockets, consider having a qualified electrician install more outlets.
6. All surge protectors are the same.
Fact: Not all surge protectors provide the same level of protection. High-quality surge protectors with adequate joule ratings offer better defense against power surges. Cheap models may fail during a surge, leaving your devices unprotected.
7. You only need RCD protection in wet areas like bathrooms.
Fact: RCDs are essential throughout your entire home, not just in wet areas. They provide life-saving protection by disconnecting power when a fault is detected, whether it’s caused by a faulty appliance, damaged cable, or contact with water.
8. You can reset a tripped circuit breaker and forget about it.
Fact: While resetting a tripped breaker may temporarily restore power, frequent trips indicate an underlying issue, such as overloading, faulty wiring, or a faulty appliance. Always investigate the cause or call an electrician if it keeps happening.
9. Old wiring is fine as long as it hasn’t caused problems yet.
Fact: Old wiring, such as cables with black rubber or lead insulation, degrades over time and can become a fire or shock hazard. Even if your electrical system seems fine, it’s crucial to have older wiring inspected and replaced if necessary.
10. Higher-wattage bulbs give better lighting.
Fact: Using a bulb with a wattage higher than your fixture’s rating is dangerous and can cause overheating, leading to fires. Always check the fixture’s maximum wattage and choose appropriate bulbs, such as energy-efficient LEDs, to achieve better lighting without compromising safety.
11. You don’t need to hire a qualified electrician.
Fact: Electrical work is complex and governed by strict safety standards. Hiring a qualified electrician ensures the work complies with regulations like Part P of the Building Regulations and reduces the risk of fire, electric shocks, and faults. Attempting to cut costs by hiring an unqualified person or doing it yourself can result in unsafe installations, fines, or invalid insurance claims.
12. My consumer unit is up to date because it has MCBs (trips).
Fact: While MCBs (Miniature Circuit Breakers) are more modern than traditional fuse wire systems, having MCBs alone doesn’t mean your consumer unit is fully up to date or compliant with current regulations. Modern consumer units should also include RCDs (Residual Current Devices) or RCBOs, which provide life-saving protection against electric shocks and reduce the risk of electrical fires. If your consumer unit lacks these safety features, it may need upgrading to meet today’s standards.
13. You can use any charger with your device.
Fact: Using non-certified or incompatible chargers can damage your device or cause overheating. Always use chargers that meet safety standards and are designed for your device. Cheap knock-off chargers can also be a fire hazard.
14. Electrical outlets or wiring in the cabinet under the kitchen sink are unsafe.
Fact: It is safe to have electrical outlets or wiring in the cabinet under a kitchen sink, as long as the area is dry and free from leaks. Properly installed outlets and wiring in this space comply with safety standards and are commonly used for appliances like dishwashers and waste disposals. However, any presence of moisture or water leaks in this area can create hazards, so it’s important to ensure plumbing is well-maintained. If you’re unsure about the condition of your wiring, have a qualified electrician inspect the setup for peace of mind.
15. Plug protectors are safe and necessary to protect children.
Fact: Plug protectors, often used by parents to protect children, can actually do more harm than good. UK electrical sockets are already designed with built-in safety features, including shutters that prevent objects from being inserted into the live and neutral pins unless a proper plug is inserted.
Using plug protectors can compromise this safety feature, as the protectors themselves may bypass the internal shutters or even damage the socket, creating potential electrical hazards. Instead of using plug protectors, focus on educating children about electrical safety and ensuring sockets are in good working condition.
