Frequently Asked Questions (FAQs)
What is a 4 pin three phase power board used for?
These power boards are used to safely distribute 415V three phase power in environments where equipment needs to be plugged in temporarily, such as construction sites, mine sites, film sets, and industrial workshops. The 4 pin design includes three active phases and one earth pin, typically for applications that do not require a neutral conductor.
What’s the difference between 4 pin and 5 pin three phase power boards?
A 4 pin board carries three phases and earth, while a 5 pin board includes a neutral conductor in addition to the three phases and earth. If the equipment you're powering requires a neutral (e.g., for single-phase loads), you'll need a 5 pin board. If not, a 4 pin version is more suitable and often used in motor-driven machinery or welders.
Are these power boards compliant with Australian standards?
Yes, all our three phase power boards are assembled in Australia using components that meet or exceed AS/NZS electrical safety standards. Each board is RCBO protected to ensure both overload and earth leakage protection, offering peace of mind on any job site.
Why is RCBO protection important on a power board?
RCBOs (Residual Current Breaker with Overload) provide dual protection against both overcurrent and earth leakage faults. This helps prevent electric shock hazards and reduces the risk of fire, especially in harsh or unpredictable working environments.
Can I use a 4 pin three phase power board for outdoor events?
Absolutely. These boards are robust and typically rated for outdoor use, provided they are protected from direct exposure to rain or immersion. They are ideal for event setups, temporary stages, and mobile food trucks requiring three phase supply.
Do I need an electrician to install or connect a three phase power board?
Yes. Any connection to a three phase supply should be carried out by a licensed electrician to ensure compliance with Australian regulations and safety standards.
