A distribution board (also known as panelboard or breaker panel) is a component of an electricity supply system which divides an electrical power feed into subsidiary circuits, while providing a protective fuse or circuit breaker for each circuit in a common enclosure. Normally, a main switch, and in recent boards, one or more residual-current devices (RCD) or residual current breakers with overcurrent protection (RCBO), are also incorporated. ==Other names== Distribution boards are also referred to as a: * breaker panel * circuit breaker panel * consumer unit, or CU * electrical panel * fuseboard * electric board * fusebox. * breaker box * load centre/center * panelboard * power breaker * service panel * DB board (South Africa) * ACDB (alternating current distribution board) * DCDB (direct current distribution board) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Distribution board」の詳細全文を読む スポンサード リンク
