Size Electrical Cable Types List

Understanding electrical wiring labeling.

Size electrical cable types list. Aside form the 3 most commonly used cable sizes of 1 1 5 and 2 5mm twin and earth there are in fact several other larger sizes of cable that include 4mm 6mm 10mm and 16mm. These are mostly used for appliances and objects that require much more electrical power to operate or special use situations. Electrical conductor wire size or gauge awg or kcmil. Ampacity rating copper wire conductors.

Electrical wires and cable have markings stamped or printed on their insulation or outer sheathing. The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 volts 60 c through 90 c 140 f through 194 f not more than three current carrying conductors in raceway cable or earth directly buried based on ambient air temperature of 30 c 86 f. A circular mil is the area of a wire one mil in diameter. What about other cable sizes.

These markings provide important information about the wiring and insulation including the wire size and material the type of insulation the number of wires contained inside a cable and any special ratings or characteristics of the wire. This number follows gauge. The coating on nmc cable is non conducting flame resistant and moisture resistant. The next wire size larger than 4 0 has a cross section of 250 kcmil.

Larger gauge wiring is used in heavy duty applications to insure that it can handle the load of current without overheating or shorting out. Rancho dominguez 2050 e. Table of common electrical wire sizes and amps or fuse ratings residential sec cable other wire ampacities for 1 3 current carrying conductors in cable earth or raceway for 120 240 volt systems sized between 100 and 400 amperes. Standard wire cable co.

But in the overhead line we use copper aluminium aluminium conductor with steel reinforced acsr galvanised steel and cadmium copper. The lower the gauge the thicker the wire. All the information you need to know about a type of cable is printed on its sheathing. Copper and aluminium conductors are the two types of electrical cables used in the electrical wiring.

Nm and nmc conductors are composed of two or more insulated conductors contained in a non metallic sheath. Cable is an important object in the electricity. It is also called conductor. Coaxial cable used for radio frequency signals for example in cable television distribution systems.

Electrical cable is a wire which is helps to conduct the current in the circuit. Will list the type of cable such as nm b or uf. Romex is a common type of residential wiring that is categorized by the national electrical code nec as underground feeder uf or non metallic sheathed cable nm and nmc. Wiring cable for the home has varying sizes or gauges specific to the type of circuit they are being used for.
