Electrical engineering is the branch of engineering that deals with the technology of electricity, especially the specification and design of electrical systems and equipment for power generation and distribution, control, and communications.
An electrical engineer who has a certifiable bachelor's degree in electrical engineering from a recognized school or university and satisfies the requirements for engineer in training (eit) and professional engineer (pe) examinations and experience can apply for the state pe license. Once state registered, an engineer by law has a primary duty to protect the public safety, health, and welfare in the facility electrical systems design by following and applying the latest building codes.
A backup power system should be designed to provide electricity to only the most important pieces of equipment in a building. It is not cost effective to have backup power available for every electrical component in a building. Most facilities, even the most critical, can be ramped down during an outage so that fuel or battery power can be conserved. As stated earlier, life safety systems are always required to be on an emergency power system. This includes lighting of egress paths, power for sprinkler pumps, and power to fire alarm systems. Hospitals will put life-saving equipment, like respirators, on standby power.
For appliances to perform at their peak levels, they need a continuous and uninterrupted flow of electricity. This is important especially for commercial hvac systems, water heaters, manufacturing equipment, lighting systems and anything else connected electrically through your business or building. Insufficient flow of power in old electrical systems can cause these appliances and equipment to malfunction. Too much power can lead to overloading. Regular wiring inspections can detect defects or interruptions in the flow of power to the appliances. Both of these wreak havoc on the components and put you and everyone in your building at risk.
Project requirements owner: electrical systems work is the new design and installation, alteration, or repair of any electric wires, wiring apparatus and other appliances used or to be used for the transmission of electricity for electric light, heat, power, signaling, communication, alarm and data transmission. Installation and modification work may also include the necessary equipment, usually consisting of a circuit breaker(s), switch(es), fuse(s) and their accessories, connected to the load end of service conductors to a building or other structure, or an otherwise designated area, and intended to constitute the main control and cutoff of the supply. Work you can do without a permit, licensed master electrician or registered design professional.
Many older circuits are not equipped to handle the same kind of load that modern electrical devices require. Overloaded circuits can lead to major problems, so any older building should be inspected before the electrical systems are used.
