CIRCUIT BREAKER PANEL WITH PROVISION FOR CONNECTING SUPPLY LINES ALTERNATIVELY TO MAIN INPUT TERMINALS ON SAID PANEL OR TO MAIN CIRCUIT BREAKER MEANS CONNECTED TO SAID INPUT TERMINALS

摘要

There is provided a panel adapted to have mounted thereon a plurality of automatic electric circuit breakers, preferably of the plug-in type, for branch circuits and provision is made to allow the coupling of electric supply lines, controlled externally of the panel box, to the input terminals on the panel, if so desired, or to prevent such coupling, if desired, and instead to couple circuit breaker means in the panel box to main breaker input terminals for the controlled supply of electricity to said panel box without decreasing the number of controlled branch circuits. The arrangement is such that the provision for alternatively coupling the said supply lines to the main circuit breaker input terminals or directly to said input terminals input terminals is mutually exclusive, i.e., the main circuit breaker cannot be plugged in if the said input are connected to supply line terminals and the supply lines cannot be connected to said input terminals if the main breaker is plugged into said input terminals.
