ABB ACU-01B 3HNA024871-001/03 Anticipated fault current device

Description

The protective conductor must always have an adequate conductivity.

Unless local wiring regulations state otherwise, the cross-sectional area of the protective conductor must

agree with the conditions that require automatic disconnection of the supply required in 411.3.2. of IEC

60364-4-41:2005 and be capable of withstanding the prospective fault current during the disconnection time

of the protective device. The cross-sectional area of the protective conductor can either be selected from

the table below or calculated according to 543.1 of IEC 60364-5-54.

The table below shows the minimum cross-sectional area related to the phase conductor size according to

IEC 61800-5-1 when the phase conductor and the protective conductor are made of the same metal. If this

is not so, the cross-sectional area of the protective earthing conductor shall be determined in a manner

which produces a conductance equivalent to that which results from the application of this table.
