Electrical Bus Bar Panel

A bus bar is an electrical conductor or group of conductors that is used to collect and distribute electrical power.

Electrical bus bar panel.

It also identifies your breaker panel s amperage capacity. Busbars are maintained at specific voltages and are typically capable of carrying high currents. 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. Electrical panels protective devices.

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. Mesh busbar connections forms a mesh like shape where breaker switching allows power from one source be directed to desired output.

Busbars can be found in electrical panels where they act as a junction of sorts for incoming and outgoing currents. 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. 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.

They are also used to connect high voltage equipment at electrical switchyards and low voltage equipment in battery banks. In other words it is a type of electrical junction in which all the incoming and outgoing electrical current meets. 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.

Single pole circuit breakers provide 120 volts and connect to just one hot bus bar. Large two pole circuit breaker that limits the amount of electricity coming in from outside to protect the circuits it feeds. 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.
