摘要:A panel, such as used to connect a building wiring system to a source of utility power, includes a voltage surge and transient protector network mounted directly thereon to be unitary therewith. The panel can be used as a stand alone panel, or in combination with other subpanels in an overall system. Each of the subpanels can include its own protector network, or can include further elements of the protector network partially included on the main panel whereby all of the panels in an overall system co-operate to form the voltage surge and transient protection network. The protection networks disclosed in U.S. Pat. Nos. 4,675,772 and 4,835,650 are integrated into panels to form protection networks. Enhancements for high neutral currents and isolated ground buses are included with the panel and protective elements in various forms of the invention.
