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.
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.
There is always the main circuit breaker which is also known as 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.
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.
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. 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.
Depending various factors, it can be prudent to make an independent connection between the neutral wire to the ground rod. Here, the ground bus bar connected directly and electrically to the neural bus of the main service panel.
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.
