Electrical wiring is an essential part of any building, whether commercial or residential. It is the backbone of our electrical systems, carrying the electrical current that enables us to use the appliances and devices that make our lives comfortable and efficient. However, working with electrical wiring is not a task to be taken lightly. It requires proper knowledge, skills and precautions to ensure safety and avoid any mishaps. 

Unfortunately, many people make common mistakes when working with electrical wiring, which can have severe consequences and result in an electrical emergency. In this blog post, we will discuss these mistakes and how to avoid them.

Mistake #1: Not turning off the power

One of the most critical steps in working with electrical wiring is to turn off the power before starting any work. Too often, people tend to skip this step to save time or out of overconfidence. However, this can be extremely dangerous and even deadly. Always ensure that the power supply to the area you are working on is turned off at the main circuit breaker. If you are unsure, it is best to seek professional help.

Mistake #2: Using the wrong wire size

The size of the wire is crucial as it determines the amount of electrical current it can handle. Using an undersized wire can overheat and potentially cause a fire, while using an oversized wire can lead to inefficiency and unnecessary costs. It is essential to consult a professional or refer to the appropriate wire size charts to ensure that you are using the correct size for your wiring job.

Mistake #3: Not following electrical codes and standards

Electrical codes and standards exist for a reason, and it is vital to follow them when working with electrical wiring. These codes and standards ensure that all electrical systems in a building are installed and maintained safely. Failure to comply with these codes can lead to fines, failed inspections, and, most importantly, safety hazards. Always make sure to follow the local building codes and national electrical standards when working with electrical wiring.

Mistake #4: Not using proper tools and equipment

Using the right tools and equipment is crucial when working with electrical wiring. Using the wrong tools or damaged equipment can lead to accidents, injuries, and damage to the electrical system. Always make sure to use insulated tools, wear proper protective gear, and regularly check and maintain your equipment.

Mistake #5: Overloading circuits

An overloaded circuit can cause electrical appliances to malfunction, lights to flicker or – even worse – start a fire. It is essential to distribute the power load evenly across different circuits and avoid plugging in too many devices at once. Be mindful of using extension cords, which should only be a temporary solution, never a permanent one.

Mistake #6: Not correctly grounding the system

Proper grounding of the electrical system is crucial for safety. It protects against shock, distributes the electrical current, and diverts any excess electricity away from the system. Always consult a professional electrician to ground your electrical system properly.

Mistake #7: Not seeking professional help when needed

Electricity is not something to mess around with if you do not have the proper knowledge and skills. In Australia, the law requires all electrical work to be carried out by a licenced electrician. It is always better to seek professional help and ensure the safety of yourself and those around you.
