What is a non sheathed cable?

Non-metallic sheathed cable, also called NM cable or Romex, after the popular brand name, is a flexible electrical cable with a plastic outer coating. That's the non-metallic sheath. Inside the sheath are two or more insulated wires and usually a ground wire. That's for safety.

What is the meaning of Armoured cable?

Steel wire armoured cable, commonly abbreviated as SWA, is a hard-wearing power cable designed for the supply of mains electricity. It is one of a number of armoured electrical cables – which include 11 kV Cable and 33 kV Cable – and is found in underground systems, power networks and cable ducting.

What is metal sheathed wiring?

BX is also known as Armor Clad, or Flexible Metal Conduit cable. BX is sheathed in a flexible metal spiral made either from aluminum or galvanized steel. BX provides all the advantages of NM cable plus some additional benefits. The flexible metal sheathing is easy to install, about as easy as NM cable .

How deep do electrical lines have to be buried?

3. Electrical Wire Encased in PVC Conduit. The National Electric Code (NEC) sets the required burial depth of electric wire in rigid, non-metallic conduit, such as PVC, at 18-inches. Cable in any conduit, including PVC, that is buried at this depth is not in danger of being severed or disturbed by normal digging.

What is a UF cable?

Multiple conductor UF-B cable may be used for interior branch circuit wiring in residential or agricultural buildings at conductor temperatures not to exceed 90°C (with ampacity limited to that for 60°C conductors) as specified by the National Electrical Code.

What is NM type cable?

Southwire's Romex^® SIMpull^® Type NM-B (non-metallic sheathed cable) may be used for both exposed and concealed work in normally dry locations at temperatures not to exceed 90°C (with ampacity limited to that for 60°C conductors) as specified in the National Electrical Code¹ NM-B cable is primarily used in residential

What does MC stand for in electrical?

When used with appropriate conductors, metal-clad (MC) cable and electrical metallic tubing (EMT) have nearly identical uses but quite different working characteristics. Therefore, on any given job, it's advantageous for electricians to use both types in concert.

What does NM stand for in wire?

UF cable. • “UF” = underground feeder; rated for in-ground and damp-area installation. • Looks like NM-B cable, but the wires are embedded as a group in solid thermoplastic (rather than individually encased in flexible thermoplastic).

What is non metallic sheathed cable used for?

Non-Metallic Sheathed Cable. Definition: Nonmetallic-sheathed (plastic) is a type of covered electrical wire consisting of at least two insulated conductors and one bare conductor used in residential wiring.

What is a stranded wire?

A wire is a single, usually cylindrical, flexible strand or rod of metal. The term wire is also used more loosely to refer to a bundle of such strands, as in "multistranded wire", which is more correctly termed a wire rope in mechanics, or a cable in electricity. Wire comes in solid core, stranded, or braided forms.

What is nm in wiring?

Romex 12/2 NM wire. Amazon.com. Romex® is the brand name for a non-metallic (NM) building wire made by Southwire that is widely used by professional electricians and DIYers alike. Romex is used for many common household electrical projects like outlets and lights.

What is the SE cable?

Southwire Type SE, service entrance cable is primarily used to convey power from the service drop to the meter base and from the meter base to the distribution panelboard; however, the cable may be used in all applications where Type SE cable is permitted.

What is armored cable used for?

Commonly known as SWA cable, the steel wire armoured cable is a power and auxiliary control cable, designed for use in mains supply electricity. Used for underground systems, cable networks, power networks, outdoor and indoor applications, and cable ducting.

What is TW insulation?

TW/THW is a solid or stranded, soft annealed copper conductor insulated with Polyvinylchloride (PVC). It is UL rated for 600 volts. #10, 12, and 14 AWG are 19 strands, all others are “highly flexible” stranding constructions.

What is Thhn wire used for?

THHN Wire. The most popular type is THHN wire. THHN stands for Thermoplastic High Heat-resistant Nylon coated. THHN can come in stranded or solid conductors depending on the size. It is either manufactured in copper or aluminum and covered in a PVC (polyvinyl chloride) insulation with a nylon jacket.

What is metallic cable?

Metallic sheathed cable (or armored cable, AC, or BX) Multicore cable (consist of more than one wire and is covered by cable jacket) Paired cable – Composed of two individually insulated conductors that are usually used in DC or low-frequency AC applications.

What is NMC cable?

"Type NMC. Insulated conductors enclosed within an. overall, corrosion resistant, nonmetallic jacket." "Type NMC cable is for use in dry, moist, damp, and corrosive locations, and Type NM cable is for use in normally dry locations." It's not clear whether NMC is a unique type or just another designation for UF.

What is a TC cable?

Type TC Control Cable XHHW-Solonon ® Jacket. Southwire's Type TC Control Cable is for use in industrial power or control circuits where small diameter, flame retardant cables are desired. Primary installations include cable trays, raceways and outdoor locations where supported by a messenger wire.

What is a use cable?

Southwire Type RHH or RHW-2 or USE-2 conductors are used with conduit as specified in the National Electrical Code ¹When used as Type USE-2, conductor is suitable for use as underground service entrance cable for direct burial at conductor temperatures not to exceed 90°C. When used as RHH, conductor temperatures shall

What is a PV wire?

Photovoltaic wire, also known as PV wire, is a single-conductor wire used to connect the panels of a photovoltaic electric energy system. PV systems, or solar panels, are electric-power production systems that capture sunlight in order to produce electricity through an energy conversion process.

What is SEU cable?

SEU/SER/SE. Southwire Type SE, service entrance cable is primarily used to convey power from the service drop to the meter base and from the meter base to the distribution panelboard; however, the cable may be used in all applications where Type SE cable is permitted.

What is SER wire stand for?

There is a bit of uncertainty on this, sometimes the exact meaning of these type of designation can be lost, but the consensus is the "U" stands for unarmored and the "R" stands for round. Here lies knowing the difference. SEU cable can only be used up to the the service disconnect (as a service entrance conductors).

What does the acronym Seu stand for?
