FAQ

Common Questions About DB Box Upgrades

How do I know if my DB box needs upgrading?
Signs your DB box needs upgrading include: frequent tripping, burning smells from the panel, scorch marks, buzzing sounds, rust or corrosion, or if your home still uses an old porcelain fuse box. We provide free assessments to determine if upgrade is needed.
What is the cost of DB box upgrade in KL?
DB box upgrades in KL typically range from RM800 to RM3,000 (2026 pricing) depending on amperage, number of circuits, and whether you need single-phase or three-phase. We provide free on-site assessments for accurate quotes.
How long does a DB box upgrade take?
A typical DB box replacement takes 4-8 hours depending on complexity. We usually complete the job in one day, including testing all circuits. Power will be off during work hours.
Do I need single-phase or three-phase power?
Most Malaysian homes use single-phase (240V), sufficient for typical loads. If you're adding multiple high-power appliances like aircons, water heaters, or EV chargers, you may need a three-phase upgrade. We assess your needs and recommend accordingly.
How do I know if my DB box is outdated?
Your DB box is likely outdated if it still uses rewirable fuses instead of MCBs, has no RCCB/ELCB earth leakage protection, shows signs of rust or discolouration, or is more than 20 years old. Electrician ProX offers free assessments to check whether your DB box meets current Suruhanjaya Tenaga safety standards.
Do I need a licensed electrician to replace a fuse box in Malaysia?
Yes. Under Malaysian law, all electrical installation work including fuse box replacement must be carried out by a Suruhanjaya Tenaga (Energy Commission) registered electrician. DIY fuse box work is illegal and dangerous - it can void your home insurance and create fire or electrocution risks. Electrician ProX technicians hold valid ST certification for all distribution board work.
