Full House Electrical Repair in Bukit Jalil

The Client's Problem

The homeowner, Mr. Azlan, reached out to us after experiencing a series of frustrating electrical issues in his 18-year-old double-storey terrace house in Bukit Jalil. Over the past few months, the problems had been escalating: the kitchen circuit breaker kept tripping whenever the kettle and rice cooker were used at the same time, several power sockets on the first floor had stopped working entirely, and there was a persistent burning smell near the distribution board that had his family genuinely worried.

He'd already called two different handymen who had attempted quick fixes—replacing individual sockets and resetting the tripped breaker—but the problems kept returning. By the time he contacted Prime Electrician, he was ready for a proper, thorough diagnosis rather than another temporary patch.

What We Found

Our senior electrician conducted a comprehensive inspection of the entire electrical system, starting from the TNB meter and working through every circuit in the house. The findings were concerning but unfortunately common in terrace houses of this age:

• Overloaded kitchen circuit: The entire kitchen was running on a single 20A circuit—not unusual for homes built in the early 2000s, but completely inadequate for today's appliance usage. The kettle alone draws 13A, leaving almost nothing for other appliances.
• Deteriorated wiring connections: Several junction points in the ceiling void had loose connections with visible heat damage and discolouration. This was the source of the burning smell—a serious fire hazard.
• Faulty RCCB: The main RCCB in the DB box was no longer tripping at the correct threshold, meaning it would fail to protect against earth leakage. This is a life-safety issue.
• Dead sockets: The first-floor sockets had failed due to a single corroded connection point feeding the entire ring circuit. One bad joint had taken out six sockets.
• Outdated DB box: The original 8-way consumer unit was undersized for the home's current electrical demands, with no room for additional circuits.

Our Repair Plan

Rather than applying more band-aid fixes, we proposed a comprehensive repair plan that would address the root causes and future-proof the electrical system:

Day 1: DB Box Upgrade and Critical Repairs

• Replaced the 8-way consumer unit with a new 16-way DB box with individual MCBs and a new 63A RCCB
• Installed a dedicated 32A circuit for the kitchen with proper 4mm cable
• Repaired all damaged junction points in the ceiling void, replacing corroded connectors with proper WAGO terminals
• Tested and verified earth continuity throughout the house

Day 2: Circuit Repairs and Testing

• Repaired the first-floor ring circuit by replacing the corroded section and re-terminating all connections
• Added a separate circuit for the water heater (previously sharing with the lighting circuit)
• Installed surge protection at the DB box to protect sensitive electronics
• Conducted full insulation resistance testing on every circuit
• Performed RCD trip testing to verify safety device operation

Client Testimonial

"I wish I'd called Prime Electrician first instead of wasting money on two handymen who only did temporary fixes. The team was very thorough—they showed me exactly what was wrong and explained everything clearly. Now my wife can use all her kitchen appliances without anything tripping, and that burning smell is completely gone. We finally feel safe in our own home again."

Lessons for Bukit Jalil Homeowners

This project is a reminder that electrical problems rarely fix themselves—they get worse over time. If your terrace house in Bukit Jalil or the surrounding areas is more than 15 years old, it's worth having a professional inspection to check for:

• Overloaded circuits that can't keep up with modern appliance usage
• Deteriorating connections that create fire risks
• Outdated safety devices that may not protect you when it matters
• Undersized DB boxes with no room for future expansion

Similar issues are common across the Klang Valley. We've encountered comparable problems in projects like our electrical hazard investigation in Petaling Jaya and our wiring repair in Subang Jaya—ageing homes with electrical systems that simply haven't kept pace with modern demands.
