A lot of homeowners are now getting into DIY projects. Apart from the savings that they can get from doing away with contractors, starting a home improvement project is an exciting activity that tickles the creativity of anyone who does it. However, wrong decisions may lead to accidents and safety risks – especially when it comes to home wiring.
If it’s your first time to encounter the term “house wiring diagram”, you need to read this short guide on home wiring basics!
What You Need To Know About Home Wiring Diagrams
A home electrical wiring diagram is a visual representation of the electrical wires and power sources inside the house, laid out in a document complete with labels. When a house is built, the construction blueprint needs to come with an electrical wiring diagram in order to determine where the wires are running, where to place electrical sockets, and which power sources are near the rooms.
A typical home wiring diagram should include the following details:
Service head: This represents the entry point of wires from the outside of the home going in.
Main service panel: Also called breaker box, this device is responsible for distribution of power throughout the building circuits.
Electrical box: This represents the endpoint or connector of wires to provide electricity via an electrical outlet or a switch.
Electric meter: This device measures the amount of power used by the home.
Ground: This serves as an electrical safety precaution by directing the electrical system to the earth or ground.
Tools Needed for Home Wiring
Here are some of the tools that you need to prepare, when planning to install or reconfigure the home electrical wiring circuitry:
Fish tape: This device pulls the wire to a conduit (either metal or PVC).
Voltmeter: This allows you to check if the circuit is “live” or not.
Wire stripper: This tool removes the wire insulation, with other variations able to cut through wire.
Linesman pliers: This all-purpose tool can twist and cut wires, and provide gripping action.
Allen wrench set: Most electrical panels use Allen screws and so this wrench set will come in handy.
Electrical tape: This adhesive tape can join two wires together or affix them on surfaces.
Safety Precautions When Handling Electrical Wires at Home
There’s nothing too safe when it comes to handling electrical circuits, and so here are some tips to make sure that safety is maintained during a home wiring DIY project:
Turn the power off: Don’t attempt to work on wires without shutting off the breaker.
Check the diagram: It’s a good practice to review the wiring diagram before diving into any circuitry modifications.
Replace old items: If you see corroded breakers and torn wires, replace them immediately.
Consult an electrical professional: When in doubt, seek help from an electrical contractor. We at Wire Craft Electric are more than happy to help.
