Important note : Users cannot be edited or removed once added to your Multi user PDF.Applies to enclosed distribution boards, which are stationary, type-tested assemblies containing protective devices, and intended for use either in household applications or in other places where unskilled persons have access to them for their use. They are intended for operation on a.c., with a nominal voltage to earth not exceeding 300 V. The outgoing circuits contain short-circuit protective devices, each having a rated current not exceeding 125 A with a total incoming load current not exceeding 400 A. This Standard is technically equivalent to and reproduced from IEC 439-3:1990, including Amendment 1:1993. Requires reference to AS 3439.1.

Replace the note by: This standard gives supplementary requirements for such enclosed distribution boards (DBU), which are stationary, type tested assemblies (TTA) for indoor use, containing protective devices and intended for use either in domestic (household) applications or in other places where unskilled persons have access for their use. Control and/or signalling devices may also be included. They are for use on a.c., with a nominal voltage to earth not exceeding 300 V. The outgoing circuits contain short-circuit protective devices, each having a rated current not exceeding 125 A with a total incoming load current not exceeding 250 A.NOTE - The nominal voltage to earth in an IT system is taken as the nominal voltage of the system.Unskilled persons normally have access to these assemblies, e.g. for switching operations and for replacing fuse-links.
