NM-B wire, or non-metallic sheathed cable, is a type of electrical wire used commonly in homes. It consists of two or more insulated wires covered by a plastic coating. This layer keeps the wires protected from harm and avoids electrical shocks. NM-B wiring is commonly used for interior components such as lighting, outlets, and appliances.
And there are plenty of good reasons to use NM-B wire. The primary one is the ease of use. This is a staple for people who enjoy doing their own home projects. NM-B wire is also more pliable than certain other wires, making it easier to snake through walls and ceilings.
It is essential to comply with the manufacturer's guidelines and local building codes when planning to run NM-B wire in your residence. This keeps everything safe. Before you start working on the circuit, make sure it is powered down. Helps protect from potential electric shocks.
The first step in installing NM-B wire is to carefully remove the plastic shield from the end to expose the insulated wire. Then, you will need to connect the wires to the proper locations and tighten the wiring nuts/screws down into place. Finally slide the wire through walls or ceilings, taking care not to bend it too aggressively or kink it as this will cause damage
Safety Rules of Working With NM-B Wire When You Work With NM-B Wire, Safety Rules Are Very Important. Always first turn off the power to the circuit you are working on to avoid shocks. Also, use safety gear — gloves and glasses — since you could cut yourself or otherwise get injured.
Never overload circuits with NM-B wire, as this can cause them to run too hot and possibly be the start of a fire. Ensure the correct AWG of wire is used for the voltage required and do not exceed the maximum amperage the wire can support.
NM-B wire is a widely-used option, but there are various kinds of wires that may work better for certain cases. For instance, compared to NM-B wire, armored cable (AC) is more durable and resistant to damage. But AC is also more expensive and more difficult to use.
