A Guide to the Components of an Electrical Panel

How the electrical panel operates is another interesting and crucial part to learn as far as electrical work and appliances are concerned. The electrical service panel allows to break the circuit of the current flowing the parts that you want to work on, so that that you can do it safely. Alternative, the main electrical service box is called a load center.

Power coming from the utility is distributed at load center to the various switches in the home. The main load center can be supplemented with an additional electrical panel, which can be of a smaller capacity, just to enhance the capacity of the main one. Inside the electrical service panel, are circuit breakers which will allow you to stop any current flow to the parts you want to work on.

The whole circuit breaking part composed of one main circuit breaker and some more smaller ones whose number depends of the number of branches involved in the whole system. The location of the circuit in the electrical panel be at the sides, bottom or at the top. The sole work of the circuit breaker is to manage power flowing to the rest of the circuit breakers.

The two wires entering the main circuit breaker from the sides, are called hot bus bars. Power will then be passed to the other circuits once the two black wires are put in the correct position by the support of the main circuit. Again, there are other two wires which come out of the main circuit proceeding to the various destinations.

Then the effect of current flow is realized in various outlets and appliances such as in lighting, heating, upon the two wires leaving the main circuit breaker. Upon return to the electrical service box, the current will do so through neutral wires, which are always white, which are then connected to the neutral bus bar. Further, the two neutral bus bars will extend the connection to the electrical service, thus completing the circuit.

The next component is composed of a main bonding jumper whereby the neutral bus bar going to the ground are connected with the main electrical service pane. Moreover, in order to control the effect of stray currents, another connection is made between the neutral wires to a rod at the ground using a copper wire.

Additionally, instead of having the last connection between the neutral wire and the rod in the ground, a separate one can be set up depending on necessity. The separate connection involves, electrically linking the ground wire with the neutral wire.

A thorough understanding of the electrical panel will enable you to do your assignment safely.
