AP1 is the base, or most basic, product model of Wieland Electric's busbar trunking system. This system is an effective, flexible and efficient method of electrical power distribution in commercial, industrial and residential environments. The AP1 trunking system is a prefabricated system of electrically conductive bars that are suspended beneath a ceiling or inside of a wall between electrical components or devices, such as switches, circuits or other electrical device. The AP1 system allows a variety of ways to customize the power distribution system and includes a range of accessories, such as insulated covers, flooring, mounting kits and more, to support the installation. The modularity of the system makes it easy to install and maintain and allows the adaptation of the power distribution system to future requirements.
