Abstract
A pre-assembled switchboard has a housing having a plurality of bus bars and a cable entrance for a plurality of sub-circuit cables and a sub-circuit termination block with conductor coupling elements configured for connection to the conductors of a plurality of sub-circuit cables. Circuit protection devices are connected between the bus bars and the sub-circuit termination block, and the conductor coupling elements being grouped by sub-circuit so that the conductors for each sub-circuit cable can be terminated adjacent to each other.
