Electrical Bus Bar Panel

In electric power distribution a busbar also bus bar is a metallic strip or bar typically housed inside switchgear panel boards and busway enclosures for local high current power distribution.

Electrical bus bar panel.

The two thick black service wires feeding the main circuit breaker each carry 120 volts from the electric meter and feed the two hot bus bars in the panel. Busbars are maintained at specific voltages and are typically capable of carrying high currents. At the back of the panel box the two bus bars vertical strips of metal that connect to each breaker to supply power to the wiring are separated in the middle with all of the main breakers connected to the top bus sections. Circuit breakers snap into place onto one or both of the bus bars to provide power to the circuits.

A bus bar is an electrical conductor or group of conductors that is used to collect and distribute electrical power. The bus bar in your home s electrical panel is the long bar on one or both sides of the panel that contain many of the electrical lines in your home s wiring. Single pole circuit breakers provide 120 volts and connect to just one hot bus bar. An electrical bus bar is defined as a conductor or a group of conductor used for collecting electric power from the incoming feeders and distributes them to the outgoing feeders.

The electrical panel typically consists of a main breaker circuit breakers and bus bars. It also identifies your breaker panel s amperage capacity.

They are also used to connect high voltage equipment at electrical switchyards and low voltage equipment in battery banks.

The positive black or hot wires run from the the circuit breakers while the neutral white and ground bare copper wires run to the bus bar completing the circuit. Mesh busbar connections forms a mesh like shape where breaker switching allows power from one source be directed to desired output. One and a half breaker busbar has two bars and three circuit breakers for output line any of the breaker can supply power to outgoing conductor.
