KL & Selangor Common Home Electrical Hazards

Many homeowners don’t pay much attention to their electrical system until problems happen. In reality, most electrical faults don’t appear overnight. They are the result of long-term hidden issues. From the daily calls we receive, the most common electrical cases include:

  • Wires overheating or catching fire: When the electrical current exceeds what the wire can handle, the insulation burns and may even lead to fire.
  • Power sockets with burning smell: If you smell burnt plastic from a socket or switch panel, it means overheating has already happened. This is a dangerous warning sign.
  • Water heater trips during shower: Many water heaters are wired incorrectly, often sharing circuits with other sockets, causing tripping whenever the heater is used.
  • Main switch, ELCB or MCB tripping: Frequent tripping is not just inconvenient, it signals leakage, short circuit, or overload problems.
  • Some lights not working or flickering: Many assume the bulb is faulty, but often it’s loose wiring, poor connections, or issues inside the DB Box.

These may look like small problems, but in fact, they are serious electrical hazards. Ignoring them not only disrupts daily life but can also put your family’s safety at risk.

Where Do These Electrical Problems Come From?

Most home electrical issues are not due to bad usage habits, but because of poor installation during wiring. Common causes include:

  1. Cutting corners: Using low-quality wires, main switches, MCB, ELCB or RCCB. At first it looks fine, but over time they overheat, degrade and may cause fire.
  2. Wrong wiring: For example, taking power for a water heater from the bedroom sockets, sharing the same line with air-cond and computer, causing overload.
  3. Old wiring not upgraded: During house renovation, many only change the appearance but not the wires. Old wires from decades ago cannot handle today’s high-power appliances.
  4. Lack of protection devices: Without RCCB, SPD or a proper earthing system, electricity has no safe release path during faults, doubling the risks.

The Serious Consequences of Electrical Hazards

Electrical safety is not about “inconvenience”. It is about life and property risks:

  • Fire: Overheating or short circuits are among the top causes of house fires.
  • Electric shock: Without RCCB protection, a leakage can directly harm or even kill.
  • Appliance damage: Unstable voltage and frequent tripping can destroy aircond, computers, washing machine, TV, oven, autogate and other expensive devices.
  • Daily frustration: Water heater trips during shower, lights flicker. These are not just annoyances, but signals of bigger dangers.

Why Hire a Professional Wireman?

Many people think professional electricians are too expensive, so they go for cheap or unqualified workers. They save a few hundred ringgit now, but leave behind a ticking time bomb.

Professional wireman can:

  • Distribute load properly and ensure heavy appliances don’t share circuits.
  • Detect old wiring and recommend correct replacements.
  • Inspect and upgrade the DB Box to ensure MCB, RCCB and main switch work properly.
  • Install SPD, lightning protection and proper earthing system.

Remember: Electrical safety is not a one-time cost. It is a long-term investment for your family’s protection.

How to Prevent Electrical Problems For Houses In KL & Selangor?

  1. Regularly check your DB Box. Frequent tripping means you must get a wireman to inspect.
  2. Install RCCB, MCB, SPD. Prevent leakage, overload and lightning surge damage.
  3. Pay attention to sockets and switches. If you smell burning, stop using and call an electrician immediately.
  4. Replace old wiring during renovation. Don’t just repaint walls, the hidden wires are the real issue.
  5. Always hire an experienced wireman. Do it right once and your family will enjoy long-term peace of mind.

Cheras 住家经常跳电问题, 家里电源一直断!

Cheras 住家经常跳电问题, 家里电源一直断! 上个星期,我们接到一位来自 Cheras 的屋主电话,他讲到整个人都要崩溃了。他说:“我已经关掉全部开关了,为什么 DB 还会 tendang(跳闸)!” 其实这种情况,很多马来西亚人都遇过。电源无缘无故跳电闸,有时候半夜跳、有时候刚要冲凉就跳,真是气死人!一开始你可能觉得只是小问题,但如果一直发生,那就代表你家电路里面已经有问题了。 可能是 电线老化、water heater 出问题、或者风扇短路,这些都会导致 main switch 一直 trip(跳闸)。 这位 Cheras 客户的情况更夸张。原来他家电路问题“历史悠久”。今年年头他刚换过一个 MCB,因为新装的 water heater 一开就跳电。后来上个月又换了两台风扇,结果其中一台突然“meletop(爆炸)”,之后另一间房的风扇也开不到了。更惨的是,有几个墙上的开关 switch也不能用了,八成是墙里面的电线已经老化 […]
