Introduction

Planning a renovation? Don't let wiring mistakes ruin your dream home.

Electrical wiring is one of the most critical aspects of any home renovation in Malaysia. Poor wiring not only puts your safety at risk but can also lead to costly repairs or failed inspections. Let’s explore the top 10 mistakes and how a trusted home wiring service can help you avoid them.

1. Ignoring Electrical Load Requirements

• Power overloads can cause fires

  Many homeowners don’t calculate the total electrical load for new appliances or extensions. This can lead to circuit overloads, short circuits, and fire hazards.

  Tip: Always consult a professional to assess your home’s load capacity.

2. Using Undersized Wires

• Small wires can't handle big loads

  Using wires that are too thin for your devices causes overheating and voltage drops. This reduces efficiency and increases the risk of fire.

  Tip: Match wire gauge to the specific current load for each circuit.

  
  

3. Skipping the Electrical Plan

• Wiring needs a blueprint too

  Renovators often skip detailed electrical planning. Without a proper layout, you risk future rework, delays, and non-compliance with Malaysia’s wiring standards.

  Tip: Get a certified electrician to draft a wiring diagram before starting work.

4. Overloading Power Points

• Too many plugs, too little safety

  Adding too many appliances to a single power point is common, especially in kitchens or entertainment areas. This can lead to overheating and breaker trips.

  Tip: Spread out high-load devices across multiple dedicated circuits.

  
  

5. DIY Wiring Without a License

• It’s not just risky—it’s illegal

  Unlicensed wiring jobs often lack proper grounding and insulation. This increases the risk of electrocution and violates local regulations.

  Tip: Always hire licensed electricians for any electrical work in Malaysia.

6. Poor Placement of Switches and Sockets

• Convenience matters

  Placing switches behind doors or too far from appliances is a usability nightmare. In wet areas, incorrect placement can even be dangerous.

  Tip: Consider both aesthetics and accessibility when placing electrical fixtures.

7. Inadequate Grounding

• Protect your appliances and yourself

  Improper grounding can damage electronics and expose you to electric shocks. It's also one of the most cited issues in failed inspections.

  Tip: Ensure all outlets and fixtures are properly grounded by a pro.

8. Using Low-Quality Materials

• Cheap now, costly later

  Inferior wires, switches, or junction boxes may save a few ringgit today but can fail early and pose serious safety risks.

  Tip: Invest in SIRIM-approved, high-quality electrical components.

9. Not Planning for Future Needs

• Think long term

  Failing to add extra sockets or wiring paths for future tech can lead to expensive modifications later.

  Tip: Future-proof your wiring with extra points and smart wiring options.

10. Not Hiring a Certified Electrician

• Experience matters

  Uncertified work can void your home insurance and lead to major safety concerns.

  Tip: Always work with licensed professionals who follow Malaysia’s Suruhanjaya Tenaga regulations.
