The two outermost cubicles (11, 11') have lead-ins, front lead-ins in one case and rear lead-ins in the other, fitted for connection to a respective incoming feeder. The middle cubicle (11') has the lead-ins of the one row individually connected by interconnections busbars (35) to the lead-ins constituting a row of the one of the adjacent cubicles that is not fitted for connection to an incoming feeder. Two cubicles (11, 11') have lead-ins in a row fitted for connection both to an interconnection busbar ad to a cable of an outgoing feeder.
