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.

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.

Basic 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.

Circuit Breaker Failure

A circuit breaker’s job is to limit the amount of current flowing on a circuit so that it doesn’t exceed the rated level. The most common cause of circuit breaker failure is continually overloading it, causing it to trip out or open the circuit.

Surge 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.

Electrical Safety Advice

Electrical safety begins with knowing some basic facts and good advice about electricity.

Energy Storage

Energy storage involves converting energy from forms that are difficult to store to more conveniently or economically storable forms.
