Electrician in Johor Bahru — DB Box Upgrade, EV Charger, Solar Hookup & Renovation Electrical
Electrician in Johor Bahru — DB Box Upgrade, EV Charger, Solar Hookup & Renovation Electrical
Johor Bahru's property renovation wave is creating substantial demand for electrical upgrade works. In older JB City and Skudai terrace houses, systems are frequently original — 30 to 50 years old, designed for a fraction of current household load. In newer Iskandar Puteri properties, the infrastructure is more current but buyers are adding EV chargers for imported Singapore-purchased electric vehicles, solar PV systems with battery storage, and multi-zone AC that the developer's base specification never anticipated.
We handle electrical upgrade works across all of Johor Bahru — renovation-grade, upgrade-focused, coordinated alongside the full project scope.
JB Electrical — Two Very Different Scopes
In older JB City and Skudai residential areas: DB box replacement (rewirable fuse boards at capacity), dedicated circuit additions for AC, rewiring sections where cable insulation has deteriorated. In Iskandar Puteri — Horizon Hills, Nusajaya, Medini, Puteri Harbour: homeowners adding home EV chargers for Singapore-purchased EVs, solar PV systems with export to TNB under the Net Energy Metering scheme, and larger AC systems. We advise on what the existing panel can accommodate and what requires an upgrade before any work begins.

Our Services
Full scope of services we provide.
DB Box Replacement & Upgrade
Old fuse boards or undersized MCB boards replaced with properly rated modern distribution boards. For older JB terrace houses, a 12-way to 18-way MCB board upgrade is typically correct. For Iskandar Puteri landed homes adding solar, EV, and additional AC circuits, we advise on the correct board capacity and sub-board configuration.
EV Charger Installation — JB
Solar System Electrical Hookup
For Iskandar Puteri and newer JB landed homes installing rooftop solar PV: we handle the electrical works for solar connection — inverter wiring, grid connection, isolation switch installation, and DB box modifications required for Net Energy Metering export. We work alongside your solar panel installer as the dedicated electrical contractor.
Wiring Upgrades & Renovation Electrical Scope
Partial or full rewiring for older JB properties, circuit additions for AC and kitchen loads, lighting, power points, and all electrical works within kitchen, bathroom, and home renovation scope.
Commercial Refrigeration
RumahPro provides commercial refrigeration electrical hookup and maintenance services for JB commercial operators. The electrical infrastructure for a walk-in cold room or display chiller installation — condensing unit circuits, control panel wiring, temperature alarm connections — is part of our commercial refrigeration scope. For JB food manufacturers in Pasir Gudang and Tebrau who run large cold room systems, we provide electrical maintenance contracts alongside the refrigeration servicing.
