There are a few different types of wire that can be used for electrical projects, so it is important to know which one is best for your project. The three most common types of wire are THHN, THWN and XHHW. Each type has its own specific benefits that make it better suited for certain applications.
THHN wire is the most common type of wire used in residential and commercial construction. It is made from a high-quality plastic that can withstand high temperatures, making it ideal for use in hot environments. THHN wire is also resistant to abrasion and chemicals, making it a durable option for wiring projects.
THWN wire is another common type of wire that is often used in wet or damp locations. The insulation on THWN wire is designed to resist moisture and keep the wires inside dry, making it ideal for use in outdoor or underground applications. THWN wire is also resistant to abrasion and chemicals, making it a durable option for wiring projects.
XHHW wire is a newer type of wire that offers several benefits over other types of wire. XHHW wires are made with a cross-linked polymer insulation that makes them resistant to heat, chemicals and abrasion. This makes XHHW wires an excellent choice for use in harsh environments or where space is limited because they can be run through smaller conduit sizes.
