type nm means non- metallic cover. it is the standard wiring used in housing nowadays.
NM Cable
The NM represents the type of sheath on the cable. NM stands for Non Metallic sheath cable..
For cable not in conduit and intended to be installed without conduit, such as NM cable, yes. You must provide some form of connector that will hold the cable in place. A clamp is not the only kind of connector that will do this but is the most common.
lol you take all the old cable out of the wall and replace it with new nm cable. It requires each wall to be tore out. Why would you want to replace all the wiring unless you were remodeling the whole apartment. Some of the old wiring if not too old is better than the new nm cable. Just convert your fuse bus panel to a breaker service and your set.
Romex is the trade name for non-metallic sheathed cable manufactured by Southwire Company, LLC.
When NM (non-metallic) cable is run through a floor, it must be protected by at least a conduit or other suitable means to prevent physical damage. This is typically required when the cable is in an area where it could be exposed to impact or abrasion. Proper protection is essential to ensure safety and compliance with electrical codes. Always consult the latest local building and electrical codes for specific requirements.
Answer varies. Is it a deep or shallow box? is there a receptical, a switch in the box as well? is it just a junction box? are they single wires or NM cable?
NM on Romex wire stands for "Non-Metallic." This type of electrical cable is commonly used for residential wiring and is designed for indoor use. The non-metallic sheathing provides insulation and protection for the individual conductors inside, making it easier to install and less prone to corrosion. NM cable is typically used in dry locations and is suitable for general-purpose circuits.
14-3 NM-B wire is a type of electrical wire used for residential wiring in non-metallic sheathed cable applications. The "14" indicates the gauge of the wire, meaning it has a diameter suitable for carrying up to 15 amps of current. The "3" signifies that the cable contains three insulated conductors (typically black, white, and bare or green for ground). NM-B stands for "non-metallic sheathed cable," which is designed for indoor use and is resistant to moisture and corrosion.
what should be the distance between instrument cable and electrical cable
Most industrialised countries manufacture electrical cable.
NM (non-metallic) or armored cable should ideally be installed at least 1 1/4 inches from the front edge of the stud. This distance helps protect the cable from potential damage caused by nails or screws that may be driven into the wall. Proper placement also ensures compliance with electrical codes and enhances the safety of the installation.
