Connection diameters are only valid for the given capacitor power levels

PFC systems with a power level of more than 300 kvar have 2 separate bus bar systems and require 2 separate feeders. The table applies to conventional or de-tuned PFC systems. The actual valid regulations (e.g. DIN VDE 0298) must always be observed.

Important note: the bus bar separation must be allocated before extending any existing systems!
