Ground Fault Interrupt Circuits Are Not Fuses

A ground fault circuit interrupter (GFCI) is a device that shuts off an electric power circuit when it detects that current is flowing along an unintended path, such as through water or a person. It's there to protect people from electrical shock, so it is completely different from a fuse.

Measuring Electrical Power

With an electrical distribution system, there needs to be a way to measure the power going into a residence or building. Every electrical service entrance needs a mechanism for accurate measurement of power consumption, as utility companies do not allow for unmetered power to be used.

Holiday Light Safety

It’s that time of year again, when the most festive of folks build awesome holiday light displays in and around their homes. Very few things are as unique to the winter holiday season as the custom of decorating your home and yard.

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.

Arizona Cooling With Circulating Fans

Circulating fans include ceiling fans, table fans, floor fans, window fans, and fans mounted to walls. These fans create a wind chill effect that helps to make you more comfortable, even if the space is also cooled by air conditioning.

How Power Transformers Work

A transformer is an electrical device that takes electricity of one voltage and changes it into another voltage. A power transformer consists of a coil wrapped around an electromagnet that transfers electricity from one circuit to another without changing the frequency of the electric energy.

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.
