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.

Phase Out of Incandescent Light Bulbs

In 2007, the U.S. federal government enacted legislation to make incandescent light bulbs more efficient by setting maximum wattage requirements.

National Electrical Codes

The National Electrical Code protects the public by establishing requirements for electrical wiring and equipment. An electrical code is a set of regulations for electrical wiring. An electrical code provides standards to ensure electrical wiring systems are safe and unlikely to produce either electric shocks or fires.

Solar Power Systems

Solar panels are made up of photovoltaic (PV) cells. A solar cell is a crystal, and the bonds are made of electrons that are shared between all of the atoms of the crystal. When light gets absorbed by the cell, electrons can move around the crystal freely, creating a current and converting sunlight into direct current (DC) electricity.

Low Voltage Electrical Systems

Low voltage refers to electrical power supplies that produce relatively low power levels. These systems use special transformers to reduce the main power supply down to a lower voltage. Low voltage wiring is the wiring for audio, video, telephone, intercom, data, alarm systems, HVAC, and generally any wiring for things using less than 24 volts.
