A fusible conductive material can be used to electrically connect or join power distribution bus bars that are placed on opposing sides of an electrically insulating bus support. The fusible conductive material can be placed in an opening or hole in the bus support with the bus bars abutting the fusible conductive material on opposing sides. The fusible conductive material can then be ignited, such as by applying a voltage drop, to produce a localized heat source suitable to electrically join the bus bars together. By electrically connecting the bus bars in this manner, the bus bars can better conduct, be less susceptible to separation and require less maintenance with respect to connectivity.
