Do Split System Air Conditioners Need Their Own Circuit?

When you want efficient cooling for your Perth home this summer, nothing beats a split air conditioning system. Many Perth homeowners are concerned about their switchboard or electrical wiring, and they wonder if their older home can handle the electrical load.

When it comes to your home’s safety, you can’t leave the question hanging. Stop wondering and seek the opinion of experts, such as Amp Electrical Perth, your trusted local partner for installing and maintaining split-system air conditioning units.

Today, let’s talk about split system air conditioning units, how they work, how Perth homeowners and landlords can upgrade to these home-improving devices, and why circuits matter!

 

How Split System Air Conditioners Are Powered

 

 

Rather than a standard power outlet, split air conditioning systems are powered by a fixed electric connection.

This means that you can’t just plug your A/C unit into the wall; you must have it hardwired.

Both the indoor and outdoor units are connected to your power supply through a dedicated electrical cable and hardwired directly to the switchboard in your home.

Since the main source of power is drawn by the outdoor compressor, you will need a stable and substantial electrical supply to ensure proper operation.

Depending on the size of the unit, power requirements for split air conditioning systems can vary tremendously, which means you’ll need an experienced sparky to ensure both a safe and reliable connection that complies with Australian standards.

 

When is a Dedicated Circuit Required Under Australian Standards?

One of the questions most homeowners have is “Do split system air conditioners need their own circuit in Perth?”

Anytime a high-energy-demand appliance is added to your Perth home, Australian standards require that you install a dedicated circuit to prevent switchboard overload.

Split air conditioning systems, reverse-cycle split systems, and ducted air conditioning fall under this category. They have high energy demands, especially larger units that are required to cool larger homes or multiple rooms.

Installing a dedicated circuit can prevent fires, circuit trips, and possibly overloading your switchboard.

All air conditioning manufacturers, as does Australian law, require professional installation for these appliances.

A fully licensed and experienced electrician can determine, based on your needs, the size of the unit you will need, your home’s overall electrical draw, whether you require additional electrical circuit, and the proper circuit board for installing your A/C unit in compliance with Australian Standard.

 

What Could Happen if a Split System A/C Shares a Circuit?

 

 

Sharing a circuit with other electrical appliances can place an excessive load on the existing power circuit board. A shared electrical circuit will not only cause frequent circuit or RCD trips but also overheating of the wiring and connectors over time, leading to major wiring problems and even failure of the circuit breaker.

It is not uncommon that, when A/C systems (whether an indoor and outdoor unit or multiple indoor units) start operating, other appliances in the home will have reduced function. You may notice that your lights dim or you might hear your refrigerator humming at a lower rate.

As a matter of safety and for proper operation, split system AC units require dedicated electrical circuit breakers for compliance with Australian law.

 

Common Misconceptions about Air Conditioning Electrical Requirements

The most common misconceptions Perth residents have about installing split system AC units include:

• A power point connection is good enough- No it isn’t. This is why Australian standards exist.
• If it’s a smaller AC unit, you can get away with a power point- Even smaller units often have big power draws, especially on startup.
• If the unit turns on and runs then it has enough power – Electrical issues often develop over time.
• Sharing a circuit will save you so much money!- This logic often leads to frequent tripping and wiring repairs down the road which will cost you far more than simply adding a dedicated circuit to start with.
• Electrical standards are only for new homes- Whenever new appliances are installed, the newest Australian standards must be met to keep your home safe and compliant.

 

Keep in mind that while your brother-in-law might consider himself a sparky, any electrical work and hardwiring of new appliances must be done by a licensed electrician.

 

Safety, Compliance, and Energy Efficiency Tips for Split Systems

 

 

A split system air conditioning unit needs proper installation to ensure cooling efficiency and prevent future problems. The cooling capacity of the unit you are considering must match the size of your home, have a dedicated circuit, and you must properly insulate refrigerant lines.

Compliance with Australian standards and manufacturer specifications is necessary to reduce excessive energy consumption, avoid performance issues (like reduced cooling efficiency), and maintain warranty coverage.

Keep in mind that you cannot install a split system air conditioning unit on your own. Use a fully licensed and insured electrician, such as your local licensed installation partners at Amp Electrical Perth, for compliant electrical connections.
