Power bus connection system with fusible conductive material

A power bus connection method comprising:

• placing a first power conductor on a first side of an electrically insulating bus support having an aperture, the first power conductor for providing an electrical power phase;
• placing a second power conductor on a second side of the bus support, the second power conductor for providing the electrical power phase to the first power conductor;
• and
• electrically connecting the first and second power conductors through the aperture using a fusible conductive material arranged between the conductors, wherein the fusible conductive material melts surfaces of the conductors together in an exothermic thermal reaction to electrically join the first power conductor to the second power conductor though the aperture upon applying of an ignition source producing a voltage drop.

A Motor Control Center (MCC) comprising:

• a section forming a shell around a device mounting volume for supporting a plurality of electrical units, the section including:
• first, second and third vertical copper bus conductors extending in a vertical direction for providing power to the electrical units, the first, second and third vertical bus conductors providing first, second and third electrical power phases, respectively, to the plurality of electrical units;
• first, second and third horizontal copper bus conductors extending in a horizontal direction across the vertical direction for providing the first, second and third electrical power phases to the first, second and third vertical bus conductors, respectively;
• and
• an electrically insulating bus support having first, second and third apertures, the electrically insulating bus support being disposed along a rear wall of the section,
• wherein the first, second and third vertical bus conductors are disposed on a first side of the bus support, and the first, second and third horizontal bus conductors are disposed on a second side of the bus support, and
• wherein the first, second and third vertical bus conductors are electrically connected to the first, second and third horizontal bus conductors at intersections through the first, second and third apertures via first, second and third fusible conductive materials arranged between conductors at the first, second and third apertures, respectively, wherein each fusible conductive material melts surfaces of conductors together in an exothermic thermal reaction to electrically join a vertical bus conductor to a horizontal bus conductor through an aperture upon application of an ignition source producing a voltage drop.
