TNB Three-Phase Electricity Application Assistance
Licencore Advisory, based in Cheras, Selangor, helps business owners with the administrative side of applying for or upgrading to a three-phase electricity supply from TNB. We help you understand the process, organise the documents and coordinate the paperwork. The technical work is handled by qualified professionals such as your electrical contractor or electrical engineer, and TNB decides on the application.
Why businesses look into three-phase supply
Some businesses need more power than their current supply provides, for example a commercial kitchen with heavier equipment, a workshop with machinery, or premises with larger air-conditioning loads. Whether you need three-phase supply, and what is required, depends on your equipment and premises. It is worth checking this before renovation and equipment purchases are finalised, so the electrical work and the application can be planned together.
