Using the data below, it is possible to determine the size of the copper bars and the
maximum permissible currents when making a rear customer connection for a
vertical, fixed Compact NS630b/NS1600, taking into account the ambient
temperature around the switchboard and the IP value.
Connection to be made according to the busbar drawings supplied.
For connection cable cross-sections and quantities, see page D-45.
