Beginners Guide to Electrical Wiring Installation

Having a basic electrical wiring installation guide is helpful, especially if you have home wiring to do. Below is a listing of the tools you'll need, as well as the basic information you’ll need to know.

Tools for Electrical Wiring Jobs

• Wire pliers – There are two basic wire pliers. One is regular flat-jawed pliers. The other is needle nose pliers. Each has a wire cutter built into the jaws. When choosing pliers, be sure what you buy has thick insulation handle grips.
• Screwdrivers – Screwdrivers aren’t complicated. There are the slotted—or flat heads—and Phillips. Slotted have both large and small heads. Use a large head when pushing open new junction box openings. Small heads, on the other hand, are perfect for creating wire connections for most all switches, appliances, and receptacles.
• Circuit tester – This helps you find the right circuit breaker when you turn it off. 
• Electrical tape – Always make sure any electrical tape you buy has a UL rating.
• Multi-meter – Don’t ever buy a cheap priced multi-meter, as it may not be accurate.
• Wire nuts – As these are used for multiple wire connections, always obtain quality wire nuts.

Electricity Is Fast

Electricity moves at the speed of light. Obviously, that's a fast property.

Grounding Is Essential

When using electricity, it must always have a continuous path to ground, including all 120 volt AC circuits (or 120 VAC). This ground, by the way, is earth.

There Are Two Main Wiring Types

Wiring for housing incorporates two wiring types for returning electricity’s path. One is referred to as a white wire ground, with the wire as part of every home circuit. The other is what’s termed an emergency, or earth ground. This one is thought of as the conductor bare copper wire located in much home wiring. Keep in mind, however, that older houses might not utilize the secondary grounding method. In such instances, any new wiring ought to be the three wire variety, termed Romex, which puts into practice stripped copper wire as its conductor’s grounding.

Know the Hot Conductor in a 120 VAC

It’s essential to know that the hot conductor is the black wire in a 120 VAC circuit system. When it comes to moving electricity to lights and appliance, this is the wire that gets it there. The fuse connection (or circuit breaker) is where it connects.

Important Information About 240 VAC Wiring System

If a 240 VAC wiring system is utilized, each wire sends a 120 VAC power into appliances. Each wire is hooked with a specialized circuit breaker that is ganged, also called double. Such circuit breakers are mostly applied to appliances with higher amperages. These may include water heaters and stoves. The white wire in a 240 VAC can be utilized to carry current, but not as a ground wire. Copper wire that is bared is the ground and hooked to the appliance’s metallic parts.

With this basic information, you will have a good overview concerning electrical wiring.
