Abstract: An improved electrical bus system maximizes the distance that electrical current must travel between adjacent buses before a short can occur by placing the buses at the top portion of upside down U-shaped channels within the insulator, and connecting the adjacent U-shaped channels at their bottom ends. The buses are exposed at each end of a bus section, with a joint insulator frictionally secured between the bus insulator and housing to provide insulation for these exposed bus ends. Adjacent bus sections are electrically connected using a snap-on connector extending across the adjacent bus sections. If a neutral bus is included, for example, in a three-phase system, the neutral bus is located directly between a pair of live buses. Because the potential between a live bus and a neutral bus is one-half the potential between two live buses, the live buses may be positioned closer to the neutral bus than another live bus.
