Water Heater Wiring & Installation

If your electrical panel is the heart of your home’s power system, then the wires are like veins. Just as your heart pumps blood through your veins to keep your body alive, the panel distributes electricity through the wires to power your home. And just like issues with your veins can lead to serious health problems, faulty wiring can pose major risks to your safety and property. Fortunately, with Mr Electrician, you’ll never have to worry. We offer professional electrical wiring services throughout Selangor and Kuala Lumpur, backed by over 25 years of hands-on experience and trusted by customers all across the Klang Valley.

Over time, wiring materials naturally degrade especially the insulation. Now imagine running a high-horsepower air conditioner, a water heater, and a washing machine all at the same time. This heavy load can cause your old or undersized wires to overheat. And when insulation is already brittle or worn out that heat can easily trigger a fire. It’s not just about performance it’s about safety.

Now picture this: It’s the middle of the night. You’re asleep in the master bedroom with the air conditioner running. Your three kids are fast asleep in their rooms with their own airconds on. The electrical load is extremely heavy. Suddenly, the aging wiring overheats… and a fire breaks out. Your doors are locked with padlocks. In the chaos and panic, there’s no time to search for keys or unlock doors. The smoke thickens, visibility drops and every second counts. By then, it could already be too late. This is why proper wiring and regular safety checks aren’t optional they’re life-saving.

Dangerous to Shower Without RCCB Protection

As per newspaper reports, all fatal cases involved failed Residual Current Circuit Breakers (RCCBs) that did not trip to prevent the incidents. Many of these cases occurred because there was no proper earth connectivity, often due to unreliable home wiring. Additionally, some incidents resulted from poor-quality earth rod clamps that were rusted or disconnected, while others occurred because earth chambers were damaged or removed during renovations, such as car porch tiling. Another possible cause is inexperienced electricians installed water heaters using undersized wires.

Over time, the live wire overheated, melted, and fused with the earth wire, causing current to leak from the live wire to the earth. When an appliance like a kettle or fluorescent lamp leaks current, and the RCCB (Residual Current Circuit Breaker) fails while the mains earthing system is broken, the leaking current seeks a direct path to earth. In such a scenario, if a person is taking a shower and the shower system is connected to a stainless steel hose and a chrome hand shower, they risk electrocution.

The current can travel through the compromised earth system, through the tank’s body, along the stainless steel hose, and then through the person’s body, exiting through their bare feet to the earth or wet floor. These findings underscore the critical importance of ensuring proper earth wiring and the integrity of electrical components to prevent accidents and save lives.

Water Heater Safety: 10mA RCCBs for All Water Heaters

For homes built before 2015 without this provision, it’s highly advised to have an RCCB installed to ensure electrical safety. This is why they have imposed a new regulation requiring every water heater to have its own RCCB (Residual Current Circuit Breaker) with a sensitivity level of 10mA. This is especially important in wet-floor areas such as bathrooms, where water heaters are usually located. If you require an RCCB for each water heater in your house, we can install them for you.

Electricity Saving

For maximum energy savings, remember to switch off power points instead of leaving appliances on standby. Don't forget to power down your heater, cooling units, and other appliances before going to bed or heading out. Additionally, make it a habit to turn off your computer whenever you're away.
