Load configurable electrical distribution bus

An assembly for distributing electrical energy from a source, the assembly defining a distribution portion and a source application portion and comprising at least six conductors, each conductor comprising at least one load connecting portion and a source connection portion, the load connecting portions being arranged in overlying layers wherein the conductors are electrically insulated one from the other and each load connecting portion comprising at least one load connection portion projecting beyond the overlying layers whereby each load is connected between two conductors at the distribution portion of the assembly, each source connection portion comprising at least one connection element, the source connection portion of each conductor being electrically Isolated from the source connection portions of all other conductors, a common conductor comprising a source connection portion having three connection elements, the common conductor for connection to a neutral reference of a three phase source, and conductive straps interconnecting selected source connection portions to electrically configure the connected loads according to one of single phase, three phase wye, and three phase delta configurations.
