What is a Consumer Main?

Consumer mains are among the unnoticed but essential components of your home’s electrical system. But have you ever wondered what precisely they are and why they matter?

You can find consumer mains inside the main switchboard of a building. They are incredibly significant as they serve as supply cables, delivering electricity to the entire property and the electrical switchboard. 

Without them, your home or building cannot get the needed power supply.

Let us tackle the things you need to know about consumer mains and understand why these components are crucial to the safety of your home’s electrical system.

Types of Consumer Mains

Most consumer mains in domestic settings might be between 6mm to 16mm. Business and multi-dwelling structures can range from 16mm and above.

Your electrical system’s maximum load determines the consumer main’s size. You can choose the cable based on its current carrying capacity.

It’s important to note that depending on its type and size, there is a possibility that your consumer mains cannot handle the amount of power and voltage needed, especially when using a smaller cable.

For instance, A 6mm cable is rated at 40 amps, a 10mm cable at 50 amps, and a 16mm cable at 63 amps. A common problem that most level 2 electricians encounter is using a 6mm cable for a consumer main. Both the cable size and type are problematic.

VIR (Vulcanised Indian Rubber) cables

The majority of older homes typically have VIR-installed cables. These outdated wiring systems may pose potential risks such as electrical fires, electrocution, short circuits, and other cabling issues.

The VIR cable is usually found within a split steel conduit. This steel conduit brings potential danger since it is electrically conductive and can become live if a power line is worn through and comes in touch with it.

If you know that these cables are present in your electrical system, consider replacing them for the safety of your consumer mains.

XLPE Cabling – The Latest Alternative

The most reliable and up-to-date consumer mains are Cross-Linked Polyethylene (XLPE). These consumer mains feature greater insulation, making them safer and more compatible with modern power needs.

They improve tensile strength, elongation and impact resistance. Moreover, the inclusion of carbon blocks enhances cut-through resistance and heat deformation.

Most importantly, these cables are made to withstand longer periods of exposure to increased voltage without melting or deteriorating.

Dealing with consumer mains, specifically XLPE, requires the assistance of a Level 2 electrician. The experts have the necessary training and legal authority to mitigate such issues immediately.

Risks of an Old Consumer Main

The total power generated at any given time would likely exceed 40 amps. If cable overloading happens, it brings potential risk to your consumer main.

An older or obsolete cabling significantly increases the dangers involving your consumer main. Moreover, if you reside in a property built over 45 years ago, you may face greater issues concerning the safety and reliability of your electrical power supply.

Here are the risks of an old consumer main:

Electrical Hazards

Your components can incur potential damages from having an old consumer main. You may encounter issues such as electrocution, frayed cables, exposed wires, fire hazards or even insulation breakdown.

Unreliable Power Supply

Old consumer mains may fail to cope with the increasing electrical demands of modern homes. 

You may experience frequent power surges, electrical supply interruptions and voltage drops, which can damage delicate electrical devices and interrupt your daily activities.

Non-Compliance

Ageing consumer mains may not follow the latest safety standards and regulations. You can face legal and safety risks with such an issue. When selling a property, ensure your outdated mains meet the regulatory requirements and evaluation.

Overloading

Your old consumer mains may struggle to manage the increased load. The risks of overloading your consumer main include overheating and frequent tripping of circuit breakers.

As households accumulate more electrical appliances and devices, older consumer mains may struggle to handle the increased load. Overloading the consumer main can lead to overheating, circuit breakers tripping frequently, and potential damage to the main.

House Mains and Defect Notices

Electrical defect notices are often provided to property owners with the danger of electrical issues. In NSW, you must upgrade your older electrical system or install a new one to adhere to the standards.

Since the consumer mains are part of your electrical system, receiving a defect notice about its condition is something you must take seriously.

Neglecting your old or damaged consumer mains has significant consequences, resulting in electrical hazards and defects. Let the inspectors find the issue and recommend the right solution.

Only authorised utility companies such as Ausgrid and Endeavour Energy can issue an electrical defect notice about your consumer main.

Additionally, turning to a level 2 electrician to resolve electrical defects concerning consumer mains is your best choice.

Don’t let electrical issues disrupt your day. Ensure to consult the experts for immediate and reliable assistance!
