a basic explanation of the wiring of an electrical receptacle (plug-in), so you'll know what to do when replacing one.

The marine-grade wire on the right has a better supply of copper, and the wire is tinned to prevent corrosion. Some builders and do-it-yourselfers use untinned wire that provides acceptable service life with their systems, so don’t fret that too much – but remember that the greater copper content and protective tinning of marine-grade wire is better in the long run.

The basics of home electrical wiring. A diagram of a single-phase 120/240V service. Whether you are considering a backup power system, want to add another electric circuit, or are going to install a new appliance, it is important to understand the home’s electrical wiring basics and applicable codes.

Let's go over the basic formulas to determine proper wire size, wire length and transformer sizing. Voltage Drop When wiring landscape lights, determining voltage drop is very important so you don't have dim lights at the end of your run. A good rule of thumb is to have no more than 8% voltage drop at the end of your wire run.

Homes in North America are supplied with a 120/240V single-phase electrical service. The incoming 240V power is split into two legs. Each leg can provide 120V hot-to-neutral, and the two legs together will supply 240V, which is used to supply heavy loads such as air conditioning compressors and cookstoves.

Most of today’s common appliances and fixtures operate off 120-volt wiring. A lot of high wattage appliances, however, will require 240 volts hookup to operate at a lower power consumption rate. A 240 volts hookup is usually provided through a two-wire cable such as 12/2, 10/2, or 8/2 or three-wire cable such as 12/3, 10/3, or 8/3, the last digit being the number of wires in the cable ...

Wiring Used With Conduit . Conduit is a hollow tube that wires are pulled, or "fished," through during installation. This differs from cable, which is a group of wires encased inside a flexible protective sheathing. The most common type of cable used in home wiring is non-metallic (NM), or Romex, cable.

Strip 1 ⁄ 2 in (1.3 cm) of insulation off the ends of each wire. Work on 1 wire at a time or else you won’t remove the insulation as well. Grip the last 1 ⁄ 2 inch (1.3 cm) of the wire in the jaws of the wire stripper and squeeze the handles together. Pull the wire stripper toward the end of the wire to cut off the insulation.
