2) simplify the testing procedure and with the consent the manufacturer, conductors with smaller cross-section than the one determined for the test current may used. Copper test conductor for test currents over 400 800 A. 5) assumed that buses with the larger surface area are arranged vertically. 24 ABB STOTZ-KONTAKT GmbH 2CDC 1Q6 Q14.
