Your day’s assignment is on the functioning of an electrical panel. Whenever you want to do any electrical repair, your first task will be to switch off power coming to the circuit of the part of repair, of which you will do at the electric panel. You may want to call it a load center and you are still right.
One of the functions of the load center is to act as a power distribution center, to all other centers which are connected to various destinations in the house. 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. A more conspicuous part of it is the door which when you open, you get access to the circuit breakers for repairs or replacements.
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. The main circuit breaker has another function of positioning the wires, so that they can supply electricity to the rest of the circuits. Furthermore, there are some two other wires leaving the main circuit breaker which are hot.
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. Then the bar connects to the main electrical service neutral which returns the current to the utility grid, and the cycle continues.
Also, the neutral bus bars connected to the ground will get connected to the main electrical service panel at the main bonding point known as a jumper. 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. Unlike with the last connection, electricity flows from the neutral wire to the ground bus.
With the guide to the parts to the major functional parts of an electrical panel, you can proceed to carry out your electrical work without any fear.
