Is Your Old DB Box in Kelana Jaya a Fire Hazard?
Many homes in Kelana Jaya, especially those built in the 60s and 70s, are still using their original distribution board (DB) boxes. These older systems were never designed to handle the high power demands of modern living and often rely on outdated MCB and ELCB technology that may not trip during an overload.
Older houses in Kelana Jaya typically have limited power outlets. To compensate, it’s common to see multiple extension cords powering 5 to 10 devices at once. This kind of overloading can cause overheating, damaged wiring and in the worst case, electrical fires especially during the night when the danger can go unnoticed.
Installing a modern DB box offers better protection and peace of mind by:
- Reducing the risk of fire
- Allowing for more power points safely
- Ensuring reliable circuit protection
If your Kelana Jaya home is still using an old DB box, now is the time to upgrade. It’s not just about following current standards it’s about keeping your family and property safe.
What Is a DB Box and Why It Matters for Setapak Homes
A DB box, short for Distribution Box or distribution board, plays a crucial role in your home’s electrical system. It’s the central point where electricity is divided and directed to different areas of your property, while also providing essential protection against electrical faults.
Inside a typical DB box, you’ll find important components like the Main Switch, SPD (Surge Protection Device), RCCB (Residual Current Circuit Breaker) and MCB (Miniature Circuit Breaker). These parts work together to help prevent electrical overloads, short circuits and potential hazards.
For homes and businesses in Setapak, we recommend using metal DB boxes, often called metal clad units in Malaysia. Compared to plastic versions, metal boxes offer better heat resistance, improved durability and higher fire safety standards.
We work with reputable brands like EPS, Maxguard and Hager which are well-known for their quality construction, compliance with local electrical codes and long-term performance.
If you’re planning an electrical upgrade in Setapak, choosing the right DB box is a smart investment in both safety and reliability.
Key Components Inside a DB Box in Kelana Jaya Homes
A DB box, or distribution board, is the central point of your home’s electrical system. It contains several key components that work together to ensure safe power distribution throughout your property. If you’re living in Kelana Jaya and planning an upgrade or installation, here’s what you need to know about the essential parts inside a modern DB box.
1. Miniature Circuit Breakers (MCBs)
MCBs protect your electrical circuits from damage caused by overloads or short circuits.
We typically use C6 MCBs for lighting and fan circuits and C16 MCBs for power sockets.
Function: Automatically shuts off power when a circuit becomes overloaded or shorted.
2. RCCBs (Residual Current Circuit Breakers)
In modern systems, RCCBs have replaced the older ELCBs. Though some still use the term ELCB, RCCB is the accurate name.
We install 40A 30mA RCCBs for power points and 40A 100mA for lighting and fan circuits.
Function: Detects current leakage by comparing live and neutral currents to prevent electric shocks.
3. Main Switch
We use a 63A double pole isolator switch as the main control point for the DB box.
Function: Allows you to shut off power to the entire DB box during emergencies or maintenance.
4. Busbars
Busbars distribute electrical current from the main power source to each circuit breaker.
Material: Usually made of copper for its excellent conductivity.
Function: Ensures even and reliable power flow to all circuits.
5. Surge Protection Device (SPD)
SPDs are installed along with the earthing system to guard against voltage spikes.
Function: Protects appliances and wiring from sudden surges caused by lightning or power fluctuations.
6. DB Box Enclosure (Plastic or Metal Clad)
This is the outer casing that holds all components.
Material: Available in metal for higher durability or high-grade plastic for insulation.
Function: Protects internal parts from dust, moisture and accidental contact.
We Use Trusted Brands for Your Safety
In Kelana Jaya, we work with reliable brands like EPS, Maxguard, ABB and Hager, depending on your preferences and budget. However, we avoid projects with extremely low budgets as we never compromise on electrical safety and quality.
When you choose genuine MCBs and RCCBs, you can expect them to perform reliably for up to 20 years. Avoid the “Rojak” Setup. Mixing random, low-quality parts might look okay from the outside but it puts your home at serious risk. A proper DB box must be built with components that are compatible and up to standard not a patchwork of mismatched brands.
Why Old DB Boxes in Kelana Jaya Homes Struggle With Modern Power Demands
Back in the day, many families in Kelana Jaya had young children sleeping in the same room as their parents. Fast forward to today and those children now have their own rooms, each packed with electrical gadgets like air conditioners, computers, printers, TVs, iPads, iPhones and even sound systems.
This change in lifestyle means more appliances are being used at the same time in different rooms. The result is a much higher demand on your home’s electrical system. If the DB box hasn’t been upgraded to match this increased load, the risks of frequent tripping, overheating or even electrical fires grow significantly.
Work-From-Home Life Adds More Load
Since the MCO, working from home has become the norm for many families in Kelana Jaya. Imagine a home where the husband, wife and kids are all in separate rooms using air conditioners, laptops and other devices at once. This puts a serious strain on older electrical systems that were never built for such heavy usage.
Overloaded Sockets Are a Common Hazard
In most cases, multiple devices are connected to a single socket using power extensions. These setups are often overloaded and increase the risk of overheating and electrical failure. If your DB box is outdated, it may not offer the protection needed to prevent a disaster.
Modern Appliances Need More Power
Today’s homes feature more high-power appliances than ever before. From autogate systems, air fryers, juicers and water purifiers to large washing machines and ovens, the total electrical demand is far beyond what older DB boxes were designed to handle.
If you live in Kelana Jaya and your DB box has never been upgraded, it may be time to take a closer look. Ensuring your electrical system can handle the load is not just about convenience — it’s about safety for your family and your home.
12 Common DB Box Problems in Kelana Jaya Homes
Many homeowners in Kelana Jaya and surrounding areas face electrical issues without realizing the real cause is their old or overloaded DB box. As homes age and more appliances are added over time, your electrical system may struggle to keep up. We’ve assisted many clients across Kelana Jaya who were dealing with frequent power trips and unsafe wiring — all due to outdated distribution boards.
Here are 12 warning signs that it might be time to replace or upgrade your DB box:
1. Your Home is Over 20 to 50 Years Old
Older homes often still use the original DB box, which isn’t made for modern electrical loads.
2. Power Trips During Lightning or Heavy Rain
This could mean your DB lacks proper surge protection or effective earth leakage protection.
3. Air Conditioner Causes Power Trips
This usually happens when the DB is overloaded or the MCBs are too weak.
4. Washing Machine Trips the Power
Appliances with high power usage may not work well with outdated circuit breakers.
5. Kitchen Appliances Trip the DB
If your oven, cooker hood or hob is tripping the DB, your kitchen upgrade may need a matching electrical upgrade.
6. Vacuum Cleaner Cuts the Power
Sudden spikes in power can expose faulty breakers or poor wiring setups.
7. More Appliances in Use Than Before
From TVs and chargers to air fryers, computers and water filters, newer devices put more demand on the system than old DB boxes were designed to handle.
8. Messy or Tangled Wiring
Unorganised wiring inside the DB makes it harder to troubleshoot and increases the chance of short circuits.
9. No Labels or Separate MCBs
Without clear labeling or individual breakers, finding the source of a problem becomes more dangerous and time-consuming.
10. Missing ELCB or RCCB
If your DB does not have an earth leakage protection device, the risk of electric shock is much higher — especially in bathrooms and kitchens.
11. Multiple Wires on One MCB
Connecting more than one circuit to a single MCB is unsafe. It can cause overheating and unreliable connections.
12. Burning Smell from the DB Box
If you notice a burnt smell near your DB, this could mean a loose wire or overheating MCB. It’s a serious warning sign that should not be ignored.
