If you think that moving into a new house only includes plumbing, interior design and cleaning, then you are practically missing a very important part– the wiring system.

When working on wiring a new house, it’s important to take a look at the essential parts of the house that needed a steady system for it. Surely this can be dangerous if not done properly. If you don’t know how to deal with electrical works and systems, it’s recommended to hire a Santa Rosa electrician.

Things To Consider in Electrical Wiring

Here are some important things to consider when wiring a new house:

Prepare tools for cutting, stripping and drilling

High quality hand tools for electrical fixes are necessary to avoid mistakes on electrical wiring, especially if you’re doing it yourself. Expert electricians suggest to invest in proper tools for cutting and stripping wires, as well as the right hand drills.

When cutting wires, remember to leave it protruding at least 3 inches from the box. Never leave a wire too short as it can be very dangerous. If you’ve mistakenly cut wires that’s too short, fix it by putting an extension of an additional 6 inches.

Know the right box 

Electrical Box InstallationWhen you take a trip to the store, there’s a lot of electrical boxes to choose from. They range from different sizes, shape and materials. How do you know which of these is the right box to use?

Electrical boxes come in either metal or plastic, made of steel, PVC and fiberglass. If you’ll be using a metal conduit to run the wiring, opt to use the metal box. For non-metallic cables, either the plastic or the metal box is fine to use. 

Also, metal boxes are best used for surface-mounted installations. The plastic ones, however come with ‘ears’ that you can use to fasten them into the wall easily.

Use non-metallic cables

Non-metallic cables (NM) are best suited for DIYers. This term refers to the outer sheathing that bundles wires together inside a cable. NM cables have 3 parts: the cable sheathing, the wire jacket and the wires.

NM cables are more recommended to use for home wiring. It’s lighter, easier to install, and a whole lot cheaper than metal cables. However, if you’re wiring outdoors, it’s best to use conduit wiring.

Cutting and stripping wires

Use a high-quality cutting and stripping tool to work with your wiring. Once you inserted the wire in place, cut 12 inches of sheathing and strip it off to reveal the wires. Experts can easily cut off sheathing wires using a simple kitchen knife, but for beginners, we recommend to use the proper tools. Cutting mistakes will leave you no choice but to do it all over again.

Push the wire back into the box and make sure at least 3 inches of shows, but electricians recommend 6 inches just to be sure. Leave one bare ground wire longer than the rest.

Group and label

Label your wires properly so you won’t get confused. It’s highly dangerous to connect wrong wires with each other. 

If you’re installing wires on switches, remember to group them accordingly. Switch wires should be installed from one direction. Hot wires and neutral wires should also be grouped.

Connect properly

Connectors or ‘wire nuts’ seal the safety on your wires. Use color-coded connections so you can easily identify the wires as well. Strip ½ or ¾ of insulation, and connect them together with a properly sized connector.

Connectors must be twisted clockwise to seal the wires together. If you’ll be leaving to continue working on the wires, it is recommended to seal a connector on the hot wires to use it as a label.

Fold and tuck them nicely and inside the box. Fold them according to this order: ground wires first, followed neutrals and then lastly, the hot wires.

Tighten it up

Never let a loose outlet or switch unfixed– it’s a disaster waiting to happen. Check all your installations if they are properly arranged, tightened and fastened to the wall. 

Loose light sockets will shift more than the tightened ones. This movement will cause more wear and tear for the wiring inside. Once wears develop, electricity can travel unpredictably along the wires. If these sockets are in the kitchen, bathrooms or wet areas, there’s a high risk of fatal electrocution.

Poor wiring connections due to loose switches and outlets are also susceptible to fires and burns. Wiring is designed to handle a specific amount of voltage, as it heats up. Poor connections can let the heat escape and develop into fire in no time.
