Electrotraders range of Three Phase to Single Phase Power Adapters
When you're working on a site with only 3-phase power available, having a safe, compliant way to run your 10A, 15A, 20A or 32A single phase gear is essential. Our range of 5 pin three phase to single phase power adapters are assembled in-house by qualified electricians using only premium Australian components.
Each unit is fitted with an RCBO (Residual Current Breaker with Overcurrent protection) to deliver peace of mind with every connection — whether you're in construction, the events industry, manufacturing, or working in remote or temporary setups.
Available in multiple amp combinations with flat or round outlets, these adapters ensure your single phase tools, appliances, and equipment run safely off a three phase supply, helping you avoid costly downtime or unsafe improvisation on site.
Frequently Asked Questions (FAQs)
What is a three phase to single phase adapter used for?
These adapters allow you to run single phase tools and equipment (typically 10A–32A) from a three phase power source, commonly used on construction sites, in industrial settings, or for temporary power setups.
Is it safe to use a three phase to single phase adapter?
Yes — provided the adapter is built to Australian standards, fitted with appropriate protection (like an RCBO), and used within its rated capacity. Electrotraders’ adapters are assembled by licensed electricians and tested before dispatch to ensure safety and compliance.
What does RCBO protection mean and why is it important?
An RCBO combines residual current (earth leakage) and overcurrent protection. It ensures your connected equipment is protected from both electrical faults and overloads, which is critical when adapting power sources.
Can I plug a 10A single phase appliance into a 32A three phase supply?
Only if you are using a correctly rated adapter, like our 32A 3-phase to 10A 1-phase units, which include the necessary protection circuitry and outlet matching. Never attempt to connect directly without an approved adapter.
Are these adapters compliant with Australian electrical standards?
Yes. All Electrotraders adapters are assembled using certified Australian components and follow best practice electrical safety guidelines. While there isn’t a single specific AS/NZS standard that applies to custom-made adapters like these, we adhere closely to the requirements of AS/NZS 3000 (Wiring Rules) and all work is done by licensed electricians.
What’s the difference between flat and round pin outlets?
Flat pin outlets are the Australian standard 3-pin plug (typically used in 10A, 15A, and 20A domestic and light commercial applications), whereas round pin versions are often used for industrial or specific-purpose gear. We offer both options to suit various site requirements.
Can I use these adapters outdoors?
Many of our adapters are built using IP-rated enclosures suitable for outdoor use, but you should always check individual product specifications. Regardless, all outdoor use should ensure protection from water ingress and mechanical damage.
Are these leads suitable for caravans or RVs?
While they can technically work for some setups, most RV and caravan parks do not provide three phase supply. These adapters are more suited to industrial applications. If you're unsure, contact our team for the correct solution.
Can I get a custom adapter built?
Absolutely. We specialise in made-to-order solutions. If you have unique power requirements, our team can build a three phase to single phase adapter to match your exact needs.
