A Guide to Electrical Myths We Hear All the Time
Some myths are harmless. Electrical myths tend not to be, mostly because the wrong assumption is usually the reason someone waited three months to call anyone. Here are a few we hear regularly.
Myth: “A Breaker That Trips Occasionally Is Just Being Sensitive”
A circuit breaker that trips repeatedly isn't being oversensitive - it's doing exactly what it's designed to do, which is protect the circuit from a genuine fault. A cable with damaged insulation, a failing appliance, or a loose connection can all cause repeated tripping. The breaker resetting and working fine afterwards doesn't mean nothing's wrong. It means the fault is intermittent, which is a different thing entirely from not existing.
Myth: “That Burning Smell Is Just Dust Burning Off the Heater”
Dust burning off a heating element does happen, usually briefly at the start of a heating season, and it fades within a few minutes. A burning smell that persists, that's stronger than a faint dusty odour, or that's coming from a socket or switch rather than a heater, is a different situation entirely - often a sign of a connection running hot, sometimes from a loose terminal or an overloaded circuit. That's not a smell to wait out.
Myth: “If the Wiring Isn't Visibly Damaged, It's Fine”
Most of a property's wiring is inside walls, under floors, or in the loft - you're never going to see the vast majority of it. Insulation can degrade with age even when nothing looks wrong from the outside, which is the entire reason EICRs exist as a testing process rather than a visual inspection. “It looks fine” and “it tested fine” are not the same claim.
Myth: “LED Bulbs Are Simple, So Fitting New Downlights Doesn't Need an Electrician”
Swapping a bulb is genuinely simple. Fitting new downlight fixtures involves working with live circuits, often in a loft space with insulation and other electrics nearby - exactly the kind of situation we've written about separately causing real fire risk when done without proper care. The bulb is simple. What it's wired into isn't.
The Pattern Behind All of These
Every one of these myths shares the same shape: something looks or sounds manageable on the surface, so it gets left. Electrical faults are one of the few things where waiting rarely makes them better and occasionally makes them a lot worse. If something feels like it's probably fine but you're not actually sure, that uncertainty is usually worth a phone call.
Frequently Asked Questions
Is it normal for a breaker to trip occasionally?
No. A breaker that trips repeatedly is protecting the circuit from a genuine fault, even if it resets and seems to work fine afterwards.
Is a burning smell near a socket just dust burning off?
Dust burning off a heater briefly at the start of a season is normal. A persistent smell, or one coming from a socket or switch, is not.
If my wiring isn't visibly damaged, is it safe?
Not necessarily. Most wiring is hidden inside walls and floors, and insulation can degrade with age without any visible sign, which is exactly why EICRs test rather than just visually inspect.
