Types of Electrical Wire and Cable and How They Are Used

Some types of electrical wire embody THHN, Romex®, UFB cable and bare copper. Each has a goal in the electrical field so I will provide you with some basic data to help you make the right decision when wiring your individual home.

THHN wire is the only conductor copper wire with a PVC insulation and a nylon coating. You possibly can discover the shiny feeling of the outside of this type of wire and the bare copper, or brass, coloration to the inside strands. This type of wire is the muse, or start, to all of the electrical cables I will discuss with you in this article.

Romex® cable is a cable with more than one THHN wire and a bare copper ground. Romex® was made so that more than one THHN wire might be run from the electrical instalasi penangkal petir box to the lighting and home equipment in your home. THHN is the wire wanted but NMB cables can ease the situation by running more than one wire at a time. The thin PVC jacket, nonetheless, can not be used outside at all even if it is only 2 or three feet.

MC cable is a metal clad electrical cable used indoors more usually to replace NMB cable and conduit together. MC cable has an aluminum interlocked armor that acts as its own conduit when used in indoor applications. It can be put in outdoor and in conduit when needed because it has all four insulated conductors.

UFB cable is an belowground cable used directly within the ground with out conduit. Sometimes underground electrical wire is used in conduit too, which can shield the cable for an extended time frame, but it’s definitely not needed. UFB cable has the tough outer jacket to resist the underneathground abuse.

You may most likely inform by the construction of these electrical cables which one is the cheapest and most expensive however I’ll inform you anyways. THHN is just one wire so it will be the most cost effective and the UFB cable is the most costly because of the building and available use outdoors.

Be sure you communicate to your wire and cable provider in order to understand exactly what you’re going to buy. There are so many completely different types of wire and cable that it’s totally difficult to get precisely what you want unless you ask around. There are very slight variances between every wire with a view to provide all functions with the proper insulation and voltage requirements.
