Electrician Johor Bahru: Tripping, Wiring, DB Box and EV Chargers

Electrician JB price list: what each job costs

What an electrician in Johor Bahru costs at RumahPro, job by job:

All costs are confirmed in a written fixed quotation before work begins, and what we quote is what you pay unless you change the scope. Jobs that are not in the table, such as a tripping fault, extra power points, lighting or a partial rewire, get the same written, itemised quote after a site visit or photos of the job.

Why does the power keep tripping at home?

When the MCB trips every time the aircond and the kitchen run together, the cause is usually overload: several high-load appliances share one circuit that was never sized for their combined load. In older JB terraces the aircond was often wired onto the general circuit rather than a circuit of its own. We check how the load is spread across your circuits, then add a dedicated circuit or raise the DB box's capacity, whichever the check shows. A dedicated aircond circuit is RM 200 to RM 400 a unit.

Sometimes the aircond itself is what trips the breaker, not the wiring. We test both, and finding out which one it is does not cost you twice. A fault inside the unit is aircond work, and aircond repair Johor Bahru starts with a RM 79 diagnosis that comes off the bill if you go ahead; a fault in the circuit is priced as electrical work. If the power trips at other times, WhatsApp or call 010-204 7500 and describe what happens; we arrange a site visit or ask for photos, and the repair is quoted in writing before any work starts.

Wireman Johor Bahru: house wiring and rewiring

In older JB City Centre and Skudai terrace houses the wiring is often the original, 30 to 50 years old and designed for a fraction of today's household load. We rewire in part, replacing the sections where the cable insulation has deteriorated, or in full: a full rewire of a 3-bedroom terrace is RM 3,500 to RM 7,000.

Smaller wiring jobs, such as new circuits for aircond and kitchen loads, lighting points and power points, are each quoted in writing before we start.

DB box replacement and upgrade in JB

An old rewirable fuse board, or an MCB board too small for the circuits it now feeds, is replaced with a properly rated modern distribution board. For an older JB terrace house a 12-way to 18-way MCB board is typically the right upgrade, and replacing a 12-way board costs RM 600 to RM 1,200 with materials and labour.

Landed homes in Iskandar Puteri that are adding solar, an EV charger and more aircond circuits need a different answer, so we advise on the board capacity the house needs and how any sub-board should be set up. Either way, you hear what your existing board can carry, and what needs an upgrade, before any work begins.

Aircond circuits, power points, lighting and ceiling fans

If a new aircond needs a circuit of its own from the DB box, we assess the load and add the dedicated circuit for RM 200 to RM 400 a unit. The unit itself goes in through aircond installation Johor Bahru, where a standard wall split is RM 350 to RM 550, install only, within a 3-metre pipe run on existing electrical.

Ceiling fans are RM 150 to RM 300 a unit to install. Extra power points and lighting, in one room or through the whole house, are quoted the same way as any job outside the price list.

Home EV charger installation in JB

RumahPro installs home EV chargers of every brand. A home charger needs a dedicated circuit from your DB box, correctly sized cable and an outdoor-rated socket or charger mounting point, so we first check what your board can carry, then advise the right installation for your charger and the way you charge. EV charger installs are done in every JB area listed below. More on the job is on our page for home EV charger installation in Johor Bahru.

Electrical contractor in Johor Bahru for renovations and solar

In a kitchen, bathroom or whole-home renovation, we do all the electrical renovation work inside that scope: circuits for aircond and kitchen loads, lighting, power points and rewiring where it is due.

For rooftop solar on a landed home, we do the electrical side: the inverter wiring, the isolation switch and the DB box changes, working alongside your solar panel installer.

Plumbing and aircond work in JB are booked on the same 010-204 7500, so the plumbing, electrical and aircond parts of one renovation stay with one team.
