If you’re in the market for a new home electrical service, there are some essential facts you should know. Generally, your utility company covers the line portion of your electrical service, including all wiring and equipment up to the electric meter. In addition, the utility will cover all maintenance, repairs, and replacement costs up to this point. Any repair work beyond this point is your responsibility.

Nonmetallic (NM) cable

Nonmetallic (NM) cable is a type of cable used for residential electrical service Washington, DC. It is made of copper wires that are parallel to one another but are not in contact with one another. These wires are then bundled into a tight bundle to make them easier to run. There are several ways to bundle up these wires, but using a non-metallic sheathed electrical cable (NMS) is the most common method.

NM cable is commonly used in residential construction. It is flexible and fire-resistant. It is usually made of two thermoplastic insulated wires and is best installed inside floor cavities or walls. The cable is labeled UF if it is designed for in-ground installations.

Romex cable

The Romex cable is a common form of electrical cable. It is a non-metallic-sheathed wire that is more flexible than metallic wires. Its sheathing is generally made of PVC material and can be white, red, or black. This sheathing helps prevent tampering and can withstand the stress of pulling through a hole.

There are two types of Romex cable, one for indoor and one for outdoor use. Type “NM” is for use in enclosed spaces (under the floor, inside walls, and ceilings), while type “NMC” is for outside wiring.

Plastic-sheathed cable

A plastic-sheathed cable for residential use has several advantages over knob and tube types. It has two layers of insulation that protect the individual conductors and the entire bundle, reducing the risk of electrocution. The plastic is also very durable and moisture-resistant. Its splices are done in junction boxes, which protect it from pests. It also contains all the wires needed for the circuit in one neat package.

Cables with multiple strands are commonly found in homes. There are several types, including bare copper, plastic-sheathed cable, and metal-clad cable. These cables come in different colors and materials. Typically, they are black, silver, or white with a brown or green insulated ground wire.

BX cable

Choosing the correct type of cable is critical to protecting your home. Some kinds of BX cables are allowed to be exposed, while others need to be enclosed in walls or underneath the floor. Before you start wiring your home, check with your local building codes to determine the type of cable you need. There are also differences in how they are installed. For example, NM cables are typically installed in walls. When choosing which line to use, follow local building codes and check the product’s insulation.

While the National Electrical Code forbids the use of BX cable in wet locations, the armored cable is an acceptable alternative. This cable is also suitable for basements and unfinished areas. However, it is essential to remember that you must have a permit to install this cable. In addition, you need to use the proper connectors.
