As a homeowner, it's a good idea to have a basic understanding of the most common types of wires used in your home. That knowledge can ensure the safety and efficiency of your home's electrical system. So, in this article, we're going over the most common types of wire used in homes so you can make informed decisions about electrical work and repairs.
Copper: The most common type of wire used in residential electrical systems is copper. Copper is an excellent conductor of electricity. It's also very durable, making it a popular choice for home wiring. Plus it's easy to work with. That makes it residential electricians top choice, and a great option for DIY projects.
Outlet Covers: These are cheap, almost invisible, and hard to remove. That makes them useful for safety, though they can be annoying to take out when you need that outlet. There are even press-fit or locking options. Be aware that these covers only work if the outlet is new. If you have an older, looser outlet, these might not stay in. And if your covers are loose, they can turn into a choking hazard. You can also go with a full decoy panel to cover the whole thing instead.
Non-Metallic Electrical Cable: This type of cable has an outer sheathing that bundles several wires together. It's called "Non-Metallic" because the sheathing isn't metal of any kind. It often has three parts: the outer sheathing, the insulation, and individual wires. It's often used for wiring outlets, switches, and other fixtures. Like copper, NM cable is easy to work with, often inexpensive, and a popular choice for DIY projects. Romex is a common brand of "Non-Metallic" cable.
UF wire: This is a type of underground feeder (UF) wire. It's often used for wiring outdoor lighting and other outdoor electrical devices. UF wire resists moisture and can stay in the ground for an extended period of time. That can make it a good choice for use in damp or wet environments.
