Extension Leads FAQs

Single-phase extension leads are designed for everyday household and light-commercial power requirements, typically in the 10A, 15A, or 20A range. They are suitable for appliances and tools that draw moderate current.


Three-phase extension leads, on the other hand, are engineered for significantly higher power delivery. Commonly rated between 10A and 125A, these leads are used in industrial, construction, and commercial environments where large equipment, motors, or machinery require stable high-load power. The additional phases provide greater efficiency, smoother operation of heavy gear, and improved load balancing.

Definitely. We specialise in producing custom extension leads tailored to your unique specifications—whether that involves cable length, plug and socket configuration, amp rating, phase type, or specialised environmental protection. If you require a lead for harsh conditions, niche equipment, unusual connectors, or custom distribution setups, our team can manufacture a solution that aligns precisely with your operational needs.

Yes. Every extension lead manufactured by us is professionally test-and-tagged in accordance with Australian Work Health and Safety (WHS) requirements. This ensures the lead is compliant, safe for immediate use, and suitable for environments where electrical certification is mandatory—such as building sites, workshops, event venues, and commercial operations.

Yes. Every extension lead we supply is assembled by licensed electricians and undergoes comprehensive in-house testing. All applicable components meet strict Australian and New Zealand electrical safety standards, including AS/NZS 3112 and IEC 60309 where required. This ensures the products are legally compliant, safe for professional use, and suitable for regulated environments such as construction sites and commercial facilities.

CEE Form (IEC 60309) plugs and sockets are widely used in industrial, commercial, and international applications due to their rugged, colour-coded, high-current design. Australian standard plugs (AS/NZS 3112) are the conventional connectors found in domestic and general commercial settings.


When equipment or power distribution systems use different standards, we offer specially manufactured adapter leads and hybrid configurations that allow safe interoperability between CEE Form and Australian standard outlets.

Our products are built for durability and reliability in demanding Australian conditions. Depending on the specification, they may incorporate heavy duty rubber, industrial-grade sheathing, or specialised insulation designed for resistance to UV, moisture, oils, abrasion, heat, and mechanical wear. Many leads are suitable for outdoor, industrial, wet-area, and high-stress applications, making them ideal for trade, construction, events, agriculture, and marine environments.

With all assembly handled in-house, most custom leads can be built and dispatched within the same business day. Lead times may vary slightly depending on the complexity of the build and component availability. If you have an urgent or time-critical requirement, our team can often accelerate production please contact us directly for priority handling.

Yes. We supply a range of compatible plugs and sockets including 3-pin, 4-pin, 5-pin, and CEE Form options—suitable for caravan parks, RV setups, boating facilities, marinas, and portable power systems. It is important to confirm the correct amp rating, connector type, and compliance requirements for your application, and our team can assist if you are unsure.

We supply a comprehensive range of extension leads designed to meet both domestic and industrial requirements. This includes 3-pin single-phase leads as well as 4-pin and 5-pin three-phase configurations. Our selection covers traditional Australian flat-pin plugs, heavy-duty industrial round-pin connectors, and IEC 60309 (CEE Form) international-standard fittings. Current ratings span from 10A through to 125A, with cable lengths available from 1 metre up to 60 metres, ensuring suitable options for everything from household use to high-demand commercial and event environments.

Single-phase extension leads (typically 240V, 3-pin) are used for everyday household equipment and lighter commercial tools. Three-phase extension leads (415V, 4-pin or 5-pin) are designed for machinery, high-power appliances, and industrial infrastructure where significantly greater electrical capacity is required. Three-phase systems deliver more power with greater efficiency, making them essential for high-load environments.



Yes. All extension leads are built to order, which allows us to customise virtually any aspect of the assembly. You can specify exact lengths, cable sizes, plug and socket combinations, phase types, and environmental durability requirements. This ensures the final product is precisely configured for your worksite, venue, machinery, or operational environment.

Flat-pin plugs are generally used in domestic and light commercial settings and are suited to lower-power devices. Round-pin plugs, on the other hand, are designed for industrial-grade performance, offering improved durability, secure connections, and higher current capacity. CEE Form (IEC 60309) fittings add an additional layer of safety through voltage-specific colour coding and mechanically keyed designs that prevent incorrect connections.

Rubber-insulated cable provides superior flexibility, abrasion resistance, and environmental durability when compared with standard PVC cable. It performs exceptionally well in demanding conditions such as outdoor sites, event production, workshops, logistics areas, and mining operations. Its resilience to heat, impact, moisture, and chemical exposure makes it the preferred choice for heavy-duty and long-life applications.

Absolutely. Every extension lead is assembled, inspected, and test-tagged by licensed Australian electricians to meet all relevant local safety regulations. We use high-quality, standards-approved components sourced from reputable Australian suppliers, ensuring compliance, electrical integrity, and long-term reliability across all applications.

Testing and tagging intervals in Australia depend on the environment in which the equipment is used. Construction and demolition sites typically require testing every 3 months, due to the high-risk nature of these environments. Other workplaces may require testing every 6 or 12 months, depending on their WHS obligations. Always refer to your workplace or site-specific compliance requirements to determine the correct interval.

Yes. We manufacture and supply 32A CEE Form 4-pin extension leads specifically suited for powering refrigerated shipping containers (reefers). These leads are built to handle the demanding duty cycles of transport, logistics, festivals, cold-storage facilities, and other environments where reliable temperature-controlled equipment must operate continuously.
