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.

To meet these requirements Interplast introduces EDISON series SP&N Double Door distribution boards and TPN horizontal distribution boards, with increased safety and meeting the requirements of International standards – IEC 60439-3 and BSEN 60439-3.
