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. 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. The electrical panel is fitted with a door, which will give you access to other major parts of the panel, which are called circuit breakers, for breaking the current floor to the branch you want it not to.
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.
Entering into the main circuit breaker, are two black service wires, which are known as hot bus bars. As they enter they are snapped into position by the main circuit breaker so that as provide power to the circuits. Furthermore, there are some two other wires leaving the main circuit breaker which are hot.
Current leaving the two hot wires will be converted to electric energy which will be used in the various electric appliances and bulbs. There are also neutral bus bars which are connected with the two smaller neutral wires leaving the main circuit breaker. 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. 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. Here, the ground bus bar connected directly and electrically to the neural bus of the main service panel.
A thorough understanding of the electrical panel will enable you to do your assignment safely.
