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. 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.
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 at http://tikellyelectrical.com/about-us/, 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. Inside the panel box, it can be positioned at the top, at the bottom or at one of the sides. Its function is to control power going to various branches branch 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. Again, there are other two wires which come out of the main circuit proceeding to the various destinations.
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 other interesting part is the main bonding jumper, which connects the neutral ground bus with the main electrical service panel. Just adjacent to the connection is another one which involves a copper wire which links the neutral wire to the rod driven to the earth and it is the last connection which allow safe passage of stray currents.
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.
It is part of your assignment to know how the electrical service panel operates, among other Wilmington Electrical Panels services.
