How to Fix an Outlet with Reversed Polarity

It’s fairly simple to fix an outlet with reversed polarity. On a properly-wired outlet, the black wire (the hot wire or non-grounded conductor) will be connected to the gold screw, and the white wire (the neutral wire or grounded conductor) will be connected to the...

What is a Ground Fault Circuit Interrupter (GFCI)?

A ground fault circuit interrupter, also called a GFCI or GFI, is an electrical device designed to monitor current flow and upon detecting a ground fault (“leaking” current), to instantaneously open the circuit and stop the flow of electrical current.

Requirements for Closet Lights

Over the years, exposed light bulbs in closets have been the cause of many house fires throughout the country, because the heat that they generate can cause things like clothing, paper, and cardboard boxes to ignite if they are too close.

Double lugging is when two wires are placed under the same screw on a circuit breaker or on the neutral bus in an electrical panel. Double-tapping is normally done by a homeowner or a handyman who knows just the basics of electrical work.

Current, Voltage, and Resistance Defined

What is current? What is voltage? What is the difference between voltage and current? How are voltage, current and resistance related? I will explain these concepts by comparing electricity flowing through a wire to water flowing through a water hose.
