Three-phase panelboard using standard rated three-pole circuit protective devices in a grounded delta system

A standard rated three-phase, three-wire panelboard for use in a grounded delta electrical distribution system wherein one phase of a delta configured electric power supply is grounded, said panelboard comprising:

• standard three-phase rated, three-pole main connection apparatus, each pole having a supply side wiring terminal adapted to receive a power supply conductor and a load side terminal;
• three bus members connected to said load side terminal of respective poles of said main connection apparatus;
• standard three-phase rated three-pole branch circuit protective devices connected to said bus members, individual poles of said devices connectable to a respective phase of a three-phase load in a respective branch circuit;
• a multiple termination assembly comprising first terminal means adapted to receive a power supply conductor of said grounded phase, second terminal means adapted to receive a jumper power supply conductor, third terminal means adapted to receive a ground conductor from a water pipe ground, fourth terminal means adapted to receive a ground conductor from a driven rod ground, and fifth terminal means adapted to receive a bonding strap;
• and
• a jumper power supply conductor connected between said second terminal means and a said supply side wiring terminal of one pole of said main connection apparatus.
