Growing Demand for DB Box Upgrades
In recent months, we have noticed a sharp rise in enquiries about DB box upgrades. When we asked customers why they wanted to upgrade, we received many different answers. Some said their DB box is very old, and they want to replace everything from the MCCB, ELCB, and MCB to timers and the plastic box itself. Others told us their house keeps tripping, and they hope that after changing the box, the problem will finally be solved. Whether it is due to age, safety, or reliability, one thing is clear: more and more homeowners now recognize that the DB box is the heart of their home’s electrical system, and when it becomes outdated, it must be replaced before it causes bigger issues.
More Than Just a Replacement
A DB box upgrade is not just about swapping old breakers for new ones. It is about future-proofing your home’s electrical supply. With a new DB box, every circuit in your home gets the right protection through properly rated MCBs, while RCCB and ELCB units provide critical leakage protection. This helps prevent electrical accidents before they happen. Upgrading also gives you the chance to add new components like surge protection devices (SPD), timers, and extra slots for future needs. For example, if you plan to install new air conditioners, an EV charger, or heavy kitchen appliances, your old DB box simply cannot cope with the demand. By upgrading, you are not just improving safety. You are making sure your electrical system is ready for today and tomorrow.
Solving the Tripping Problem Properly
Many homeowners believe that constant DB tripping is caused by faulty components such as the MCB or ELCB inside the DB box. In reality, based on our experience repairing more than 20,000 homes, we have found that the majority of tripping cases come from hidden wiring issues, not the breakers themselves. The most common problems are wire short circuits, current leakage, and poor-quality wiring used by previous contractors. In many older houses, the insulation on the wires has broken down, causing two or more wires to short together. Another frequent issue is improper wire connections. Some wiremen simply use wire taps to wrap joined wires instead of making solid, secure connections. Over time, these joints become loose, leading to intermittent tripping, sparking, or even fire hazards.This is why a proper DB box upgrade must include full wiring inspection and testing, not just swapping components.
When we handle an upgrade, we make sure every connection is secure, every cable is tested with insulation resistance checks, and every circuit is confirmed safe before handing over. By addressing the real root causes, you get lasting reliability, not just a temporary fix.
And then another common reason for tripping is current leakage from household appliances. In recent years, the market has been flooded with cheap and low-quality appliances. Many of these OEM products are imported at the lowest possible cost due to intense price wars. Unfortunately, their weak insulation and poor build quality often lead to current leakage. When plugged in, they trigger the RCCB or ELCB to trip, which is the safety device doing its job to protect you from electric shock. However, many homeowners mistakenly think the DB box is at fault when the real issue lies with defective or unsafe appliances.
