April 10, 2012 – After three years on the market, Appleton has upgraded its PowerPlex panelboard to include an integral bus bar system which customers can order to replace the standard hard-wired system. Rated at 100 Amp, Appleton claims the new bus bar system results in greater wiring space and doesn’t require rewiring if the branch circuit ampacity increases. Suitable for use on lighting, heat trace and power circuits, the PowerPlex is engineered for Class I Zone 1 and Class I Division 2 environments like those found in petrochemical and chemical plants, waste treatment centres.
