Old DB Box in Shah Alam Homes
In areas like Shah Alam, many homes were built in the 1970s and 1980s. Now that it’s 2025, a shocking number of these houses are still using their original DB boxes. Can you imagine how outdated these systems are? Most of them were installed decades ago, using plastic enclosures, outdated MCBs, and old ELCBs that are no longer reliable.
Some MCBs don’t even trip when they should, allowing dangerous currents to flow freely. This creates a serious fire risk. We’ve also seen many homes where each room has only one power socket. To overcome this, people use double extensions and 5-gang sockets to power multiple appliances. That one wall socket could be powering 10 devices, this is extremely dangerous. Overloading leads to overheating, melted plugs, and in the worst-case scenario, electrical fires.
What if a fire breaks out while you’re sleeping? By the time you realize it, it may already be too late. Upgrading your DB box isn’t just about following modern electrical standards. It’s about protecting your family when they’re most vulnerable.
What Is a DB Box?
A DB box (Distribution Box), also known as a distribution board, is an enclosure that distributes and manages electrical power throughout your home. It houses key safety devices like the Main Switch, SPD (Surge Protection Device), RCCB (Residual Current Circuit Breaker), and MCB (Miniature Circuit Breaker).
For our installations, we use metal enclosures (often called “metal clad” in Malaysia) for better fire resistance and durability. We also recommend trusted brands like EPS, Maxguard, Hager, and ABB—brands known for high quality and compliance with safety standards.
Key Components Inside a DB Box:
- MCBs (Miniature Circuit Breakers)
- We use C6 MCBs for lighting and fan circuits, and C16 MCBs for socket outlets.
- Function: Trips automatically when there’s an overload or short circuit.
- RCCB (Residual Current Circuit Breaker)
- Older homes may still refer to ELCBs, but RCCB is the correct and current term.
- We use 40A 30mA RCCBs for power circuits and 40A 100mA for lighting/fan circuits.
- Function: Detects current leakage to earth and trips to prevent shock.
- Main Switch
- We typically use a 63A double pole isolator switch.
- Function: Manually cuts off power to the entire DB for safe maintenance.
- Busbars
- Made of copper to distribute electricity evenly.
- Function: Links power from the main supply to each individual circuit.
- SPD (Surge Protection Device)
- Installed with an earthing system for maximum lightning protection.
- Function: Protects appliances from voltage spikes or lightning surges.
- Enclosure (Metal Clad or Plastic)
- Function: Houses all the components safely. Metal provides durability and fire resistance.
We do not accept projects with extremely tight budgets that compromise on quality. When you use genuine, high-quality components, they can last up to 20 years. We advise against mixing low-grade parts from unknown sources. This turns your DB box into a “rojak” setup that puts your home at serious risk.
Old DB Boxes Can’t Handle Today’s Power Needs
Many homeowners today have completely different lifestyles compared to 30–40 years ago. Each bedroom now may have its own air conditioner, TV, laptop, printer, sound system, and more. All these devices are pulling power at the same time.
The pandemic also shifted how we live. Many parents now work from home. A home with four people in four different rooms, each with air conditioning and electronics, puts tremendous strain on a DB box designed for far fewer appliances.
If your DB hasn’t been upgraded to match today’s electrical load, it’s not just inefficient—it’s dangerous.
Modern homes also include appliances like autogate systems, Cuckoo water purifiers, ovens, air fryers, juicers, and large washing machines. These are all high-load devices. When plugged into an outdated DB box, the chances of overheating, tripping, or fire multiply.
Common Problems Homeowners Face with Old DB Boxes
We’ve helped many homeowners in Shah Alam upgrade or troubleshoot old and unsafe DB setups. Here are 12 signs your DB box may need immediate attention:
- House is 20–50 years old
Your DB system is outdated and not suited for today’s electrical demand. - Power trips during lightning or rain
Likely due to lack of surge or earth leakage protection. - Tripping when air conditioner starts
Caused by circuit overload or faulty breakers. - Washing machine trips power
Older DBs can’t handle high-draw appliances reliably. - Kitchen hood, hob or oven trips the DB
Happens when kitchen upgrades aren’t matched with electrical upgrades. - Vacuum cleaner causes trips
Sudden load surges may trigger weak breakers. - Too many new appliances added
TVs, computers, air fryers, chargers, Cuckoo units—all add more load. - Messy or tangled wiring
Poor workmanship creates troubleshooting difficulty and safety issues. - No circuit labeling or separate MCBs
Faults are harder to isolate and fix safely. - No RCCB installed
Increases risk of electric shock in wet zones like kitchens and bathrooms. - Multiple wires stuffed into one MCB
Unsafe practice that causes loose connections and overheating. - Burning smell from MCB area
A clear sign of overheating or poor contact. Requires immediate attention.
