Is Your Old DB Box Still Safe to Use?
Many homes in Port Klang, especially those built back in the 70s, 80s, and early 90s, are still using old distribution boards (DB boxes) that were designed for a much lower electrical load. Back then, a typical house had just one TV, one fridge, and a fan in each room. Fast forward to today you’ve got airconds in almost every room, TVs, iPads, Wi-Fi routers, printers, and high-power appliances running all at once. Can your old DB box keep up?
If not, you’re putting your home and family at risk. We’ve seen countless cases where outdated DB boxes failed to trip during overloads, leading to overheating wires, melted sockets, and even house fires. It’s a silent danger most homeowners never realise until it’s too late.
The Danger of Overloading – Common in Port Klang Homes
In many older homes around Taman Bayu Perdana, Taman Chi Liung, or Kampung Raja Uda, it’s common to see double extensions and multi-gang plugs powering up to 10 devices from a single socket. This kind of setup creates a serious overload. If your DB box is still using old-style plastic casings and outdated MCB/ELCB tech, it won’t provide enough protection.
Imagine if your socket melts or catches fire while your family is asleep there’s no time to react. That’s why upgrading your DB box is not just about safety it’s about peace of mind.
Why You Need a Modern DB Box
A DB box (Distribution Board) is the heart of your home’s electrical system. It controls and protects all your circuits. Here’s what we include in a modern DB box upgrade for homes in Port Klang:
Components We Install:
- MCBs (Miniature Circuit Breakers)
- C6 for lighting & fans
- C16 for power sockets
- Automatically cuts off power during overloads or short circuits.
- RCCB (Residual Current Circuit Breaker)
- 40A 30mA for power sockets
- 40A 100mA for lighting circuits
- Trips when there’s current leakage helps prevent electric shocks.
- Main Switch (63A Isolator)
- Manual shut-off during maintenance or emergencies.
- SPD (Surge Protection Device)
- Protects your appliances from lightning and voltage spikes.
- Works best when combined with a proper earthing system.
- Busbars & Internal Wiring
- High-quality copper busbars for smooth current flow.
- Neat, organized wiring to reduce short circuit risk.
- Metal Clad DB Enclosure
- Fire-resistant casing that lasts longer than plastic models.
- We recommend trusted brands like EPS, Maxguard, ABB, and Hager.
Note: We don’t mix low-quality components. No “rojak” setups. Our work follows safety standards, not shortcuts.
Power Usage Has Changed – Has Your DB Box Kept Up?
In Port Klang today, homes use way more power than before. Families often have:
- Multiple airconds
- Water heaters
- Desktop computers
- Printers
- Rice cookers, ovens, and air fryers
- Autogate systems
- Chargers in every room
And after MCO, many families continue to work from home. If your DB box hasn’t been upgraded to support all this, expect frequent tripping, overheating, or worse electrical failure.
12 Signs You Need to Upgrade Your DB Box
- Your home is over 20 years old
- Power cuts out when it rains
- Aircond or washing machine causes circuit trips
- Kitchen appliances cause DB to trip
- Vacuuming shuts off power
- Too many devices connected via extensions
- Messy wiring inside the DB box
- No clear labels on circuit breakers
- DB box has no RCCB/ELCB
- Two or more wires connected to one breaker
- You smell something burning near the DB
- The DB box looks old, worn, or overloaded
If you’ve noticed any of the above, don’t wait until something goes wrong.
