4 Electrical Habits Every Electrician Silently Judges You For
This video explains, in plain English, what every switch in your consumer unit actually does - and what to do when one trips. We cover the main switch, MCBs (which protect your circuits), RCDs (which protect you from electric shock), RCBOs, and surge protection - plus the one thing you should never do when a switch keeps tripping.
We all do it. Something's a little off with the electrics, and instead of dealing with it, we find a comforting reason not to call a professional. Here are the habits and myths that come up again and again, and why each one is worth taking more seriously than it feels at the time.
Treating a tripping breaker like a snooze button. The power cuts, you sigh, you flip the switch back on, you move on. But a circuit breaker or RCD that keeps tripping is doing its job, it's a warning sign of a real fault, not a nuisance to reset your way past. Usually it means damaged cable, a failing appliance drawing excess current, a loose connection, or moisture ingress, especially common in outdoor fittings and garden sockets. If this sounds familiar, our Electrical Fault Finding & Repairs page covers what we actually look for.
"It's probably just a loose bulb." Persistent flickering, especially across multiple rooms, isn't adding character. It often points to a loose connection at the fitting, switch or junction box, or a failing lamp driver if you're running modern LED lighting. Worth a proper look rather than another twist of the bulb.
"It's worked fine for 40 years." If the wiring hasn't caused a problem in four decades, it must be indestructible, right? Not quite. Real warning signs include an old fuse box with rewireable fuses instead of modern switches, black rubber, fabric or lead-sheathed cabling, round-pin sockets, sockets mounted straight into wooden skirting boards, or no RCD protection at all. Any of these point toward a consumer unit upgrade or, in some cases, a full rewire.
"It's probably just dust on the heater." A burning smell, or a socket that's warm to the touch, means a connection is running above its rated temperature. Often caused by an overloaded circuit, stacked extension leads and adapters are a common culprit, or a loose terminal arcing behind the wall. This isn't a quirk, it's an immediate fire hazard that needs investigating properly, not waiting out.
What to Actually Do
Stop resetting the breaker. Stop ignoring the flickering. Definitely stop ignoring a burning smell. If it's been a while since your property's electrics were properly checked, an EICR gives you a clear, professional picture of exactly what condition your installation is in, rather than a guess based on how long it's gone without an obvious problem.
Our standard hourly rate for fault finding in the Horley area is £75, and for most straightforward faults, diagnosis and repair are completed in a single visit.
Frequently Asked Questions
Why does my circuit keep tripping?
A breaker or RCD that trips repeatedly is detecting a genuine fault, not being temperamental. Common causes include damaged cable, a failing appliance, a loose connection, or moisture ingress in an outdoor fitting.
Should I worry about a flickering light?
Persistent flickering, especially across more than one room, usually points to a loose connection or, with LED lighting, a failing lamp driver. It's worth a proper check rather than assuming it's just the bulb.
How do I know if my wiring is out of date?
Warning signs include an old rewireable fuse box, black rubber or fabric-sheathed cabling, round-pin sockets, sockets mounted directly into wooden skirting, or no RCD protection. Any of these are worth an assessment.
Is a warm socket or a burning smell serious?
Yes. It means a connection is running hotter than it should, often from an overloaded circuit or a loose terminal, and it should be investigated promptly rather than left.
