摘要

The block has longitudinal chambers for receiving the longitudinal ribs (5) of respective bus-bars. Two external walls of the distribution block extend upwards and abut the edges (14) of connection limbs (20,21,23), leaving a gap (15). The external walls may comprise 90 degree bends (23), whose edges face each other.
