When it comes to electrical wiring, there are a variety of types and styles to choose from, each with their own unique benefits and uses. Here are some of the most common types of electrical wiring:
Non-Metallic (NM) Cable: Also known as Romex cable, this is the most commonly used type of electrical wiring in homes and commercial buildings. It consists of two or more wires wrapped in a sheath of plastic insulation, which provides protection from moisture and abrasion.
Armored Cable (AC): This type of wiring is similar to NM cable, but it has a metal armor layer surrounding the wires, providing additional protection from physical damage.
Conduit Wiring: Conduit wiring is a system of metal or plastic pipes that protect and route electrical wires throughout a building. This type of wiring is often used in commercial and industrial settings where the wiring may be exposed to harsh environments.
BX Cable: BX cable is a type of armored cable that has a metal sheath surrounding the wires. It is commonly used in residential wiring applications.
THHN/THWN Wire: THHN and THWN wires are single-conductor wires that are commonly used in residential and commercial electrical systems. They are made of a single copper or aluminum wire with a thermoplastic insulation.
MC Cable: MC cable is a type of armored cable that has a metal sheath surrounding the wires. It is commonly used in industrial and commercial wiring applications.
SER Cable: SER cable is a type of electrical wiring that is commonly used for large appliances such as electric water heaters and air conditioners. It consists of two or three insulated wires and a bare ground wire, all wrapped in a PVC sheath.
