Electrical DB Upgrade

Upgrading The Electrical Distribution Board (DB) Fuse Box

The distribution board—also known as a panelboard, breaker panel, electric panel, fuse box, DB box, load center, consumer unit, service panel, or electrical panelboard—plays a crucial role in any home or office. It serves as the central hub of the electrical system, directing and regulating the flow of electricity throughout the building. In essence, it functions as the brain of your electrical network.

Proper installation is essential to prevent recurring wiring issues, frequent power trips, and system failures. However, many older homes in Selangor and Kuala Lumpur still rely on outdated electrical distribution boxes (DBs), also referred to as electrical panel boxes or distribution panels.

These aging DBs often struggle to support the power demands of modern living. Appliances such as air conditioners, water pumps, ovens, water heaters, computers, and high-definition TVs require more power than these old systems can safely deliver.

As the demand for electricity continues to grow in homes and buildings, upgrading your electrical panel becomes increasingly important. Without an upgrade, older panels may become overloaded, leading to potential safety hazards and reduced performance of your electrical appliances.

Reason To Consider Upgrading Your Old DB Box

There are many reasons why you should consider replacing your old electrical panel (DB box).
Think about it—if your house was built 20 years ago, your kids were probably still very young back then. Now they’ve grown up, and each of them has added more and more electrical devices in their rooms—computers, air-conditioners, chargers, lights, maybe even their own water heaters.

It’s not safe to keep looping additional sockets or lights from the existing power points. And if you pull new wires all the way back to the DB box but connect them into the same old MCB, together with other wires, that’s even worse. You’re overloading a single MCB, and that can lead to serious risks like overheating or even fire.

Each circuit—like air-cond, water heater, or room sockets—should have its own individual MCB. That way, the load is distributed properly, and your electrical system stays safe and efficient.

Another important reason to upgrade your DB box is the condition of the MCBs. Many old MCBs are no longer up to today’s standards. Some have become loose, and others use outdated technology that may not trip reliably during a fault. That’s a serious safety concern.

Also, a lot of older DB boxes are made of plastic, which becomes brittle and fragile over time. In fact, in many homes we’ve inspected, the covers are already cracked or broken, exposing the wiring inside—which is both unsafe and unsightly.

Replacing your old DB box with a modern metal unit not only improves safety but also gives you peace of mind that your electrical system is built to handle today’s needs.

We Have Worked On Thousands Of Electrical Panels

We’ve worked on thousands of distribution panels over the years, many of which are made from plastic. A common issue we encounter is broken doors or covers, which leave live wires exposed—posing a serious safety hazard. Additionally, we often find that the four screws used to secure these panels are either loose or missing altogether.

Another recurring problem is loose MCB handles that fail to trip properly when necessary. We also frequently see poorly terminated cables and loose terminal screws, which can lead to overheating and electrical faults.

That’s why we typically recommend upgrading to a more durable, long-lasting metal distribution box. Our installations include panels with ample capacity and extra slots, allowing room for future expansion. This future-proof approach ensures you won’t need to replace the distribution board every few years as your electrical needs increase.

For core components like RCCBs, main switches, and MCBs, we generally use trusted brands such as Hager and ABB. For customers who prioritize enhanced protection, we also integrate Surge Protection Devices (SPDs) to safeguard the entire electrical system against voltage spikes and lightning surges.

If you continue using old and outdated electrical fuse box or electrical circuit breaker panels, it can lead to overload, which can cause:

1. Overheated wires
2. Overheated termination points
3. Can create a fire hazard

To avoid these dangers and ensure your home’s electrical system meets your growing power needs, contact Mr. Electrician for a professional electrical panel upgrade in Selangor and Kuala Lumpur.

We install high-quality distribution (DB) control boxes, MCBs, RCCBs, SPDs, and main switches, and carefully reorganize all wiring. If your existing wires are too short, we’ll extend them using cable links and insulate them properly with heat shrink tubing.

Every wire is neatly arranged and securely terminated, ensuring maximum safety, performance, and long-term reliability for your entire electrical system.

Replace Your Old DB Box Now

Are you concerned that the fuse box in your house is too old and no longer meets your daily electrical needs? We can study your current electrical system at your home and propose a new electrical system tailored to your needs. For DB box replacement, we normally use a Metalclad DB enclosure because it is more durable compared to PVC types. We can include a main switch, surge protection device (SPD), and MCBs with appropriate current ratings. In Malaysia, the earthing system is designed to maintain a safe level of earth resistance, typically below 10 ohms. If your electrical earthing system doesn’t meet this regulation, we can assist by installing earthing rods to achieve a reading below 10 ohms.
