It is important for you to have an understanding on how the electrical service panel works as before you start doing other electrical works in the house. For you to able work without any risks, you will need to current flowing to the area your interest, by using the circuit breakers inside the electrical service panel. Load center is another name you can use to refer to the main electrical service panel.
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. 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.
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.
A part of the main circuit breaker are two black service wires, which are otherwise known as hot bus bars, which enter it through the sides. 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.
Upon leaving the hot wires, the electric current will work through various electric appliances such as light bulbs and outlets. 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. 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.
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.
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.
