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…
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…
Read MoreBasic Units of Electricity
The three basic units of electricity are voltage, current and resistance. Voltage is measured in volts, current is measured in amps and resistance is measured in ohms. There is a basic equation in electrical engineering that states how the three terms relate. It says that the current is equal to the voltage divided by the…
Read MoreSurge Protectors
Surge protectors are devised to protect electronic devices from voltage spikes. Surge protectors limit the voltage supplied to an electric device if a voltage spike occurs. If the voltage rises above a safe level, a surge protector helps to prevent that surge from damaging your electronics. Most power surges are so brief that they are…

Read MoreArizona Household Energy Use
The average Arizona household uses about 1,100 kilowatts of electricity each month. A quarter of the energy consumed in Arizona homes is for air conditioning, which is more than four times the national average. More than 90% of Arizona households use air conditioning. In Arizona homes, space heating accounts for just 15% of total energy…
Read MoreSingle Phase and 3 Phase Power
Single Phase power is a two wire Alternating Current (AC) power circuit. Many of the residences in the U.S. use single-phase alternating current electric power supply, which is typically used for powering up lights and household appliances. Generally, there is one power wire and one neutral wire, and power flows between the power wire (through…
