The EletraSub Distribution Board is is a component of an electricity supply system which divides an electrical power feed into subsidiary circuits while providing a protective fuse or CB for each circuit. Scope. criteria and standards for electrical power supply and distribution systems. In order to transfer electrical power from an alternating current (AC) or a direct current (DC) source to the place where it will be used, some type of distribution network must be utilized. Export to PDF. Square D 9080 power distribution blocks (PDB) have short circuit current ratings (SCCR), which are now required by NEC 2005 and UL 508A for industrial control panels. A Distribution System Operator (DSO) enables access to the network, securely operates and develops an active distribution system comprising networks, demand, and other fl exible distributed energy resources (DER).
