How the electrical panel operates is another interesting and crucial part to learn as far as electrical work and appliances are concerned. 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. Alternative, the main electrical service box is called a load center.
In the main electrical service panel, power coming from the utility is distributed to various branches connected to various appliances, and outlets in the home. Again depending on the level consumption of power and power distribution network in the home, there can be need for additional smaller panel.Besides the main electrical service panel, then can be a small electrical panel, just in case the area of power utilization is large. 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.
Circuit breakers are many, but there is one big one called the double -pole service connect. The location of the circuit in the electrical panel be at the sides, bottom or at the top. Its function is to control power going to various branches branch circuit breakers.
The two wires entering the main circuit breaker from the sides, are called hot bus bars. As they enter they are snapped into position by the main circuit breaker so that as provide power to the circuits. 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. The current will then return to the main circuit breaker through white neutral wires, which proceed to link with big wires, which are also neutral. The whole circuit will get completed when the main electrical service panel is connected by the two main neutral bus bar, before extending it to the main power grid.
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.
Depending various factors, it can be prudent to make an independent connection between the neutral wire to the ground rod. The separate connection involves, electrically linking the ground wire with the neutral wire.
It is part of your assignment to know how the electrical service panel operates, among other electrical services.
