Consumer mains are the electrical cables that connect your property to the electricity network and supply power to your switchboard. If they're damaged, outdated or unable to support modern electrical demands, they may need to be upgraded by an authorised Level 2 electrician. Whether you're installing an EV charger, upgrading to three-phase power or replacing ageing electrical infrastructure, a consumer mains upgrade helps ensure your electrical system stays safe, compliant and capable of meeting your property's current and future power needs.
Many homeowners don’t think about their consumer mains; many don’t even know what they are. Whether you’re planning on installing an EV charger, upgrading to three-phase power or replacing an ageing switchboard, your consumer mains play a crucial role in safely delivering electricity to your home.
Since consumer mains are part of your home’s connection to the electricity network, they can’t be upgraded by a normal electrician. This type of work has to be performed by an insured and licensed Level 2 electrician to disconnect and reconnect your electricity supply safely.
What Are Consumer Mains?
Consumer mains are the main electrical cables that connect your home or business to the electricity network. These cables carry electricity from the point of supply to your switchboard, where it's distributed safely through your property.
Every light, appliance and power point relies on the cables to receive power. If your consumer mains are damaged, undersized or are showing signs of wear and tear, it may struggle to safely handle your home’s electrical demand.
A consumer mains upgrade involves replacing or upgrading your electrical cables. This upgrade needs to be performed by a licensed Level 2 electrician.
When Do You Need A Consumer Mains Upgrade?
While consumer mains are designed to last for decades, they don’t last forever. As Sydney homes are using more and more electricity and adding more appliances, many older properties aren’t designed to support all that extra power.
The most common reasons homeowners need a consumer mains upgrade include:
- You’re upgrading to Three-Phase power
- Damaged or cracked insulation
- Corroded connections
- Weather-related damage
- Your home’s electrical demand has increased
- You’re planning on adding high-powered appliances like ducted air conditioning and pool equipment
- EV Charger and Solar Systems
- Your consumer mains are old and not safe anymore
Will My Power Be Turned Off During A Consumer Mains Upgrade?
For our Level 2 electricians to work as safely and efficiently as possible, your electricity will need to be temporarily disconnected. But don’t worry, our team will always let you know how long the outage will go for and what you need to do to prepare.
Why Consumer Mains Upgrades Are Important To Your Property’s Safety
Consumer mains are responsible for supplying every circuit in your home or business with electricity and power. Like other electrical cables, consumer mains naturally deteriorate over time. If your consumer mains are damaged, overloaded or undersized, it can create significant and serious safety risks.
Upgrading your consumer mains helps to:
- Reduce the risk of overheating, electric shock and electrical fires
- Improve the safety of your overall electrical network
- Provide a reliable power supply to your home
- Support larger and more powerful electrical loads safely
- Reduce voltage drop and electrical faults
- Ensure your home is safe and complies with current NSW and Australian Standards
- Future-proof your electrical system and property
Upgrading your consumer mains also provides you with greater peace of mind and helps you to protect your home as well as your pets, belongings and family.
How Does A Level 2 Electrician Perform A Consumer Mains Upgrade?
Unlike standard electrical work inside your home, a consumer mains upgrade involves working directly on your property's connection to the electricity network.
A Level 2 electrician will typically:
- Inspect your existing consumer mains
- Assess your property's electrical load requirements
- Determine the correct cable size for your property
- Safely disconnect your electrical supply
- Remove the existing consumer mains
- Install new compliant consumer mains
- Upgrade associated electrical equipment where required
- Test the new installation
