Nikola Tesla Was an Inventor and Futurist
Nikola Tesla was an inventor and futurist who is best known for his contributions to the design of the modern alternating current (AC) electricity supply system. Tesla tried to put his inventions to practical use in his Wardenclyffe Tower project, an intercontinental wireless communication and power transmitter. Tesla’s intention was to develop a system that…
Read MoreSmart Homes of the Future
Smart Homes of the future using the Internet of Things will require specialized electrical needs. IoT devices can include lighting, heating and air conditioning, media and security systems, and wiring for data. Wiring designs for smart homes include in-wall transmitters, whole-house surge protection, and isolating non-automation loads. The long-term benefits of a smart home include…
Read MoreStatic Electricity
Static electricity is named in contrast with current electricity, which flows through wires or other conductors and transmits energy. Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge. Static…
Read MoreElectrical Troubleshooting
Troubleshooting is a systematic search for the source of a problem in order to resolve it. Electrical Troubleshooting is problem solving used to repair failed electrical circuits on machinery or an electrical system. Depending on the type of equipment, troubleshooting can be a very challenging task. Troubleshooting includes identifying a probable cause for a problem,…
Read MoreElectrical Code Compliance
The National Electrical Code establishes requirements for electrical wiring and equipment. Electrical codes provide standards to ensure electrical wiring systems are safe. Electrical contractors use the NEC for estimating, designing and installing electrical systems. Professional, licensed electrical contractors stay current with the NEC requirements. Maintaining compliance with the requirements of the National Electrical Code provides…
Read MoreThe Electrical Transformer
An electrical transformer is an electro-magnetic device that works by converting electrical energy from one value to another. A transformer has no moving parts and is a completely static solid state device. The primary winding of a transformer is connected to the input voltage supply and transforms the electrical power into a magnetic field. The…
Read MoreElectrical Short Circuit
A short circuit is any condition where the establish wiring circuit is interrupted by a flaw in the wiring or wiring connections. The term short circuit is used to refer to the situation in which a hot wire carrying current touches a neutral wire. When this happens, resistance lessens instantly and a large volume of…
Read MoreElectrical Wire Gauge
Wire gauge is a measurement of wire diameter. This determines the amount of electric current a wire can safely carry, as well as its electrical resistance and weight. Wire is sized by the American Wire Gauge (AWG) system. Wire gauge refers the physical size of the wire. Whenever a circuit is extended or rewired, or…
Read MoreResidential and Commercial Electrical Circuits
Electricity is a flow of electrons. A complete circuit is needed for electricity to flow. From the main electric service panel, electricity is divided into circuits throughout a building. The maximum amount of load that can be placed on any single circuit is controlled by a circuit breaker. Building circuits are parallel circuits. A parallel…
Read MoreLow Voltage Wiring
Low voltage wiring is the wiring for audio, video, telephones, alarm systems, HVAC, and generally any wiring for things using less than 24 volts. Low voltage is often used only with small electrical systems as it is not suitable for large-scale electrical projects. There are very real safety risks associated with low-voltage systems. Low-voltage can…
