Electrician in Petaling Jaya, DB Box Upgrade, Rewiring & Electrical Renovation Works

The PJ Older-Home Electrical Problem

In the older SS estates, SS2, SS3, SS4, SS5, SS6, Damansara Jaya, the most common electrical issue is a combination of three things: an undersized DB box that cannot accommodate additional circuits, original wiring aged well beyond its practical service life, and a cumulative load that trips the main breaker when multiple high-load appliances run simultaneously. Signs to watch for: frequent MCB trips, burning smell near sockets, warm outlet covers, flickering lights, or a DB box with rewirable fuses. Any of these in an older PJ terrace warrants an assessment before renovation.

DB Box Replacement & Upgrade

Replacing old fuse boards or undersized MCB boards with properly sized modern distribution boards. For a 3-bedroom PJ terrace house, a 12-way to 18-way MCB board with correct labelling is the standard upgrade. We test all circuits after installation and provide a handover sheet showing circuit assignments.

Electrical Wiring Upgrades & Rewiring

Partial rewiring for specific rooms or circuits, kitchen, bathrooms, AC circuits, without necessarily rewiring the entire property. Full rewiring for older properties where cable insulation has degraded throughout. We minimise wall hacking and reinstate surfaces properly.

EV Charger Installation

EV home charging is growing rapidly in Petaling Jaya, particularly in the Ara Damansara, Damansara Perdana, and Kelana Jaya corridors where the professional and expat demographic has a high rate of EV adoption. We install dedicated 32A or 40A circuits and mount the charge point at the correct location in your car porch or garage.

Downlight installation, LED feature lighting, additional power points, USB charging sockets, ceiling fan installation, and all electrical works within kitchen, bathroom, and home renovation scope. Planned before walls are closed.
