In building and house constructions, it is important to have a good electrical plan. Professional electrical engineers ensure that the electrical system is sound and Eco-friendly. Electricity is used for lighting, heating, air conditioning, and communication devices like telephones and computer, among others.
Local utility companies or power plants provide current to transformers which then travels to different establishments to supply their needs. Because it has passed many channels, the electricity that arrives in the homes and buildings are weakened. To remedy this, many have standby generators as alternatives.
Here’s a list of the basic considerations for a sound electrical system
- What is ideal: 220V or 110V?
For modern homes, the voltage needed is 220 which means that the power transmitted is twice that of a 110V. The higher the voltage, the thicker the copper wire is needed. The issue here is more about economics.
A rich country like the USA can afford to install a safer electrical system that uses thick and bigger copper cables to produce 110V compared to developing and poorer countries whose best option is to use thinner, lighter, and smaller copper wires to produce 220 voltage.
- Why do we need a fuse and circuit breaker?
When there is a power overload, electrical equipment will be likely destroyed. Sometimes, these overloads can cause fires and shortages. The fuse and service breaker protect an overloaded electrical circuit. It stops the flow of electricity from the source to the equipment. Both the fuse and circuit breaker are found inside a panel and usually mounted in a wall.
- What is the main panel and where should it be placed?
The main panel is also known as the panel board that can contain up to six circuit breakers. This is where electricity enters from the service utility. This is the main distribution system for all electrical circuits. The main breaker is placed on the panel that can easily shut off power to all the circuits. It is placed strategically near the power utility’s meter. In case of power surges, it automatically turns power offs.
- What other electric devices are found in our homes or offices?
Before, outlets are two-pronged. Now, it is common to have three-pronged outlets. The third prong has a grounding wire that protects against electric currents escaping the circuit, causing unwanted and dangerous shocks.
An electric meter is a device provided by the utility company to measure how much power is used for a particular period. The unit of measurement used by the electric meter is kilowatt-hour which is equal to the amount of energy used by a load of one kilowatt for a one hour period.
Electrical boxes connect the wiring system. It can be an outlet, a switch or a junction box. It is important to select the right boxes based on the building codes to make sure that the homes and buildings are safe and secure.
Everywhere we are, electricity is needed and used. Though we may not be familiar with it, all these elements power our homes and make our lives easier.
