Understanding the Different Types of Electrical Wiring

No one really thinks about the wiring running behind the walls unless there’s a power outage or a serious electrical problem that needs to be fixed. However, it’s important that you know the type of electrical wiring installed in your home for safety and maintenance reasons. This information may also come in handy when you’re installing an electrical system in your new property. Mr. Electric looks into the different types of electrical wiring and their characteristics.

1.     Romex (NM-B Cable)

Romex cable, also known as non-metallic sheathed cable, is a common type of electrical wiring used for branch circuits. It consists of two or more insulated copper conductors and a bare copper ground wire. This type of wiring boasts exceptional durability, affordability, and flexibility, making it easy to install. However, it’s not suitable for wet locations like bathrooms or outdoors. If you have Romex wiring in wet locations of your home, call a professional electrician for rewiring.

2.     Armored Cable (AC)

As the name implies, armored cable consists of a protective layer of metal armor. Unlike the Romex cable, which is covered by a non-metallic sheath, this type of wiring offers enhanced protection against physical damage, moisture, and fire. Armored cable wiring is often found in older homes and buildings built in the mid-20th century. It is one of the most versatile electrical wiring in Gentry, AR. The notable downside associated with armored cable wiring is that it’s more difficult to install due to the rigid metallic sheath.

3.     Conduit Wiring

Conduit wiring consists of cables running through protective pipes, known as conduits. This type of wiring has been around for well over 100 years,and it’s commonly used in commercial and industrial settings. The protective tube offers superior protection against physical damageand pests. Conduit wiring can be used in various environments, meets safety standards, and it’s easy to maintain.

4.     UF-B Cable (Underground Feeder Cable)

Designed for direct burial in the ground, UF-B cable is a robust choice for outdoor wiring. Its tough outer jacket provides excellent protection against moisture, abrasion, and the elements, making it ideal for connecting outbuildings, lighting fixtures, and other outdoor electrical needs.
