  • Patent number: 9373948
    Abstract: The present invention relates to an electrical distribution board. The electrical distribution board comprises at least one incoming conductor terminal, at least one outgoing conductor terminal, at least one longitudinal bus conductor connected to the at least one incoming conductor terminal, at least one lateral conductor tab connected to the at least one bus conductor for distributing electrical power from the at least one bus conductor to the at least one outgoing conductor terminal, and at least one isolation mechanism for electrically isolating the at least one outgoing conductor terminal from the at least one lateral conductor tab. The at least one isolation mechanism is moveable between a first position in which the at least one outgoing conductor terminal is electrically isolated from the at least one lateral conductor tab and a second position in which the at least one outgoing conductor terminal is electrically connected to the at least one lateral conductor tab.
