Residential 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…

Low 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…
