Patent ID: 8305739

Claim:
A panelboard, comprising: a housing having a low-amperage section and a high-amperage section, the low-amperage section being configured to receive only low-amperage circuit breakers having an ampere rating between about 10 and 100 amps, the high-amperage section being configured to receive only high-amperage circuit breakers having an ampere rating between about 100 and 1200 amps; a first vertical busbar, positioned completely within the low-amperage section of the housing, for distributing a first phase of electricity entering the panelboard to a first plurality of low-amperage circuit breakers capable of being coupled to the first vertical busbar; and a horizontal busbar, positioned completely within the housing, for distributing the first phase of electricity to a plurality of high-amperage circuit breakers capable of being coupled to the horizontal busbar in the high-amperage section of the housing, the horizontal busbar being electrically connected and generally perpendicular to the first vertical busbar.
