Frequently Asked Questions (FAQs)
What is an industrial extension plug?
An industrial extension plug is a heavy-duty electrical connector designed to safely deliver power in harsh environments. Commonly used on construction sites, in factories, and for temporary power setups.
What’s the difference between single phase and 3 phase plugs?
Single phase plugs are typically 3-pin and used for standard 240V power, while 3 phase plugs have 4 or 5 pins and support 415V, making them suitable for powering heavier equipment.
Are your extension plugs weatherproof?
Yes — most of our plugs are IP66-rated for protection against water, dust, and UV exposure. They’re built tough for outdoor and site-based use. Please check the individual product specifications.
What amperage options are available?
We stock plugs from 10A up to 50A in 3-pin, 4-pin, and 5-pin configurations.
Do your plugs meet Australian standards?
Absolutely. Every extension plug we sell complies with AS/NZS safety and performance standards.
When would you use an angled extension plug?
Angled plugs are ideal when space is limited — such as behind switchboards, machinery, or in caravan and generator setups. The 90° design allows for neater cable management and prevents strain on the cord.
