DB Board Troubleshooting Services in Singapore
Your distribution board is the control centre of your home's entire electrical system. When breakers keep tripping, circuits are overloaded, or your panel cannot handle modern electrical demands, professional DB board troubleshooting and upgrading is essential. We diagnose faults, replace defective components, and upgrade panels for safe, reliable power.
Your Home's Electrical Control Centre — Diagnosed & Fixed
Your distribution board (DB box) is the heart of your home's electrical system — it distributes power to every circuit and houses the MCBs and RCCBs that protect your home from electrical faults. Many older HDB flats have DB boards with limited circuit slots that were designed for basic lighting and a few appliances. Today, with multiple aircon units, water heaters, induction cooktops, and EV chargers, these boards are often running at or beyond their capacity. When circuit breakers keep tripping, labels are missing, or your board cannot handle your electrical needs, it is time for professional attention. We diagnose DB board issues, replace faulty or outdated breakers, add new circuits, and upgrade entire panels to meet current safety standards and your household's actual electrical demands.

DB Board Troubleshooting FAQs — Singapore
A DB (Distribution Board) is the electrical panel in your home that distributes power to all circuits. It contains circuit breakers (MCBs) that protect against overcurrent and safety switches (RCCBs) that protect against earth leakage and electric shock. In Singapore, the DB board is typically located near the main entrance of HDB flats or in a utility area for condos and landed homes.
Consider upgrading if your board is over 15 years old, you are adding major appliances like aircon units or an EV charger, experiencing frequent trips, or planning a renovation. If your board has no spare slots for new circuits, an upgrade to a larger panel is the way forward.
Yes, if your board has spare slots, adding new circuits is straightforward. If not, we can upgrade to a larger panel to accommodate additional circuits. We recommend choosing a panel with a few spare slots for future flexibility.
A typical DB board upgrade takes 4-6 hours depending on the number of circuits and complexity. Power will need to be off during the work, but we aim to minimize downtime and will let you know the expected duration before starting.
You can safely switch MCBs and RCCBs on and off — they are designed for user operation. However, do not open the panel cover or touch any wiring inside. If you smell burning or see scorch marks on your DB board, turn off the main switch and contact us immediately.
