  • How to tell the positive and negative terminals in your home s electrical panel

    How to tell the positive and negative terminals in your home s electrical panel

    According to master electrician James Hornof, for DC power, the red wire is generally positive and the black wire is usually negative. The red wire is a phase 2 hot wire, and the white wire. When you're dealing with electrical wiring, it's important to know which is positive and which is negative—but how are you supposed to tell them apart? The easiest way to tell is by looking at the color, but the colors mean different things depending on what kind of power is being used. Whether you are replacing a fixture, troubleshooting a circuit, or simply trying to understand your home's electrical. The positive wire carries the current from the power source to the load, while the negative wire returns the current back to the source. To identify the positive wire, look for markings such as a plus sign (+), the color red, or words like “positive” or “pos” on the wire insulation.

  • There s a draft in the electrical panel at home

    There s a draft in the electrical panel at home

    Drafts are easy to identify and fix using simple methods like feeling for airflow, using a candle test, and installing inexpensive foam insulation pads behind outlet and switch plates. Is your home suffering from drafts coming in around your electrical outlets? You're not alone. It is possible they are signs of air leaks, which can lead to reduced energy efficiency and higher monthly energy costs. Whether you're feeling the chill or you're tired of receiving high electricity bills, you should check your electrical. A foam insulation gasket, sometimes called an outlet sealer, is a thin, pre-cut piece of closed-cell polyethylene foam designed to fit precisely behind the plastic cover plate of an electrical outlet or switch. These gaskets create an air-tight seal between the wall surface and the faceplate. As cold weather sets in each year, you may notice new drafts creeping into your home.
