Bus system connecting bus bars and a method of connecting bus bars

A method of assembling an electrical distribution bus system, the method comprising the steps of:

• providing at least a first bus bar, the first bus bar including a first elbow portion from which a first pair of straight portions extends, a first portion of said first pair extending at a first elbow angle to the first elbow portion, a second portion of said first pair extending at a second elbow angle to the first elbow portion, and the first and second portions of the first pair being disposed in respective planes disposed at right angles to one another,
• providing at least a second bus bar, the second bus bar including a second elbow portion from which a second pair of straight portions extends, a first portion of said second pair extending at a third elbow angle to the second elbow portion, and a second portion of said second pair extending at a fourth elbow angle to the second elbow portion, and the first and second portions of the second pair being disposed in respective planes disposed at right angles to one another,
• disposing a dielectric insulator having a length and a width with the length extending perpendicularly between the elbow portions of the first and second bus bars, the width being no greater than twice the length, and
• engaging one fastener to couple the dielectric insulator between said bus bars, the dielectric insulator electrically insulating the first and second bus bar from one another.
