Home Wiring: 4 Types Of Electrical Cables A Licensed Electrician May Recommend

Electrical wiring is a critical part of any building and home. It's essential to have the right type of electrical cable installed to ensure your system's safety, functionality, and longevity. A licensed electrician can help you select the right cable type for your project and install it correctly. They can consider the different cables' prices, performance, and installation requirements to find the best fit for your needs. Here are four types of electrical cables a licensed electrician may recommend:

Nonmetallic Sheath Cable (NM)

Nonmetallic sheath cables are color-coded and have simple installation steps. They are ideal for indoor residential wirings such as lighting circuits, outlets, and switches. You can also install the cables in walls, ceiling spaces, and attics, as they use a plastic covering to protect the wire from external elements and moisture. NM cables are also cost-effective, durable, and semi-flexible. They also have fewer trim pieces than other cables, making them easier to install.

Metal Clad Cable (MC)

Metal-clad cable is ideal for home projects that need more protection from environmental conditions, such as moisture and temperature. For instance, MC wires will be the ideal option when installing a cable near a water heater. The cable is encased in steel or aluminum armor to protect against mechanical abuse. However, MC cables are more expensive due to their robust features and additional installation components.

Underground Feeder Cable (UF)

Underground feeder cables are designed for outdoor installations such as underground conduits and direct burial. The cable is water-resistant and can withstand rough terrain, so it's ideal for installations in wet or moist areas. It has a thick, solid-insulated covering that protects the wire from direct contact with soil and other external elements. You can also install UF cables in a conduit when they need extra protection. 

Shielded Cable (S)

If your home wiring requires extra protection from interference, such as radio waves, shielded cables may be an ideal option. The cable is encased in a metal shield that blocks external interference from getting into the cable. Shielded cables are more expensive than other electrical wires and require exact installation steps to ensure the shielding is effective.

No matter the type of electrical wiring you need for your home, a licensed electrician can help you find the right cable option that meets your needs and budget. Whether it's nonmetallic sheath cables, metal-clad cables, underground feeder cables, or shielded cables, with the help of a professional electrician, you can install the cables correctly to ensure your electrical system is safe and efficient. Contact a licensed electrician today for professional advice on the best cable type for your home wiring project.
