Important Disclaimer: Installation of Hardwired Electrical Products in Australia
Please read the following information, including the disclaimer at the bottom of this page;
by purchasing from Buzz Energy Systems, you understand and acknowledge these terms.
When it comes to the installation of hardwired electrical products in Australia, it is important to be aware of the regulations and guidelines in place to ensure safety and compliance.
As per the Electrical Safety Act, installations operating at ELV (Extra Low Voltage) levels of 120 VDC and below can be installed by individuals with the necessary knowledge and skills.
However, it is crucial to note that installations operating above ELV levels require the expertise of licensed electricians and experienced installers. Products falling under this category are not suitable for DIY (Do-It-Yourself) installation and must be handled by professionals. Attempting to install such products without the proper qualifications can not only compromise performance but also invalidate any manufacturer's warranties.
At Buzz Energy Systems, we recognise the importance of reliable and efficient installations that prioritise safety, performance and warranty compliance. Our team consists of qualified tradespeople and specialists who are equipped with the expertise required to handle complex electrical installations.
For installations that operate above ELV levels, we strongly advise against DIY installation. Instead, we recommend seeking professional assistance from licensed electricians and experienced installers to ensure the proper installation and optimal performance of such products.
When it comes to installing hardwired electrical products above ELV levels, rest assured that Buzz Energy Systems can provide the necessary qualified tradespeople and specialists. Our professional installation services guarantee compliance with regulations, the preservation of manufacturers warranties and most importantly, your safety.
Do not compromise on the installation of your hardwired electrical products. Trust Buzz Energy Systems for a professional and hassle-free experience.
