To answer this question the size of the cable or the amperage of the load is needed to calculate the correct wire size and connectors to fit the cable.
There is actually no specific formula used to work out cable size. In order to determine the type of cable you need and the size you need, you need to know the source of the supply, the voltage of the system, the ambient temperature, and the method you plan on laying out the cable.
Assuming it is a 400 V three-phase motor, the phase current is 11 amps, or more if the power factor is less than 1.0 (or the supply voltage is different). If it is a 400 V motor the cable should be capable of carrying 16 amps, so a 2.5 mm-sq 4-core cable is needed.
1) determine load /design current. eg 13kw oven Ib=13000W/230V if 3 phase- 13000w/1.73*400V =56.52A In(circuit breaker size)=60A 2) In/ C1+C2+C3 (c is coefficient of ambience temperature of type of cable referred to BS tables) 3) value of above refer to BS tables for appropiate cale size. eg. based on 60A cable size is 16mm2 pvc/pvc cable size
A 'core type' transformer core is one in which the primary windings and secondary windings are placed around each of the limbs, as opposed to a 'shell type' core, in which the two windings are placed across the centre core. A core-type core is a magnetic circuit equivalent to an electric series circuit, whereas a shell-type core is equivalent to an electric parallel circuit.
The NM represents the type of sheath on the cable. NM stands for Non Metallic sheath cable..
It depends to Overall Diameter, type of armor, Lead Cover and voltage grade.
Coaxial cables usually include a solid plastic core. The core is made of solid insulation material that helps to maintain the shape and structure of the cable, while also providing insulation for the inner conductor. This type of cable is commonly used for television and internet connections.
Fiber optic cable has a glass or plastic core that carries light signals for high-speed data transmission over long distances.
The recommended type and size of cable for a 240-volt, 30-amp circuit is a 2 2 2 4 SER cable.

In the electrical trade devices that are used to support a cable or conduit entry into an electrical device are called connectors. These can be called strain relief,sealtite, EMT, or BX but they are all called connectors When the word gland is used it usually refers to the wiring of explosion proof devices. When making a wire end, the conductors are fed through an empty gland that is twisted on to the end of the explosion proof cable. Into this empty gland is poured a epoxy type compound that hardens itself around the conductors. The hub of the fitting slides over the gland and is screwed into the threaded hole of the device that connects to the cable. By sealing the cable in this method, explosive gasses or dust that might seep into the electrical device is prevented.Pyrotenax, a mineral insulated cable, is one type of cable that uses this method of sealing its cable ends. These type of wire ends are also used with Tech cable that are used in explosion proof areas.
PVC is polyvinyl chloride. It is a very durable and thick type of plastic. It is used often for home piping and irrigation.
Coaxial cable is a type of cable that has a single inner-core wire. This wire is surrounded by a layer of insulation, a woven metal shield, and an outer jacket. Coaxial cables are commonly used for television, internet, and other data transmission applications.

Follow this four steps: 1. Slide the outer protective locking nut and clamping ring down the cable that will enter the structure, case, or panel. Slide the main body of the cable gland into the device, panel, or structure case. Secure the main body with the locking nut on the other side of the barrier. 2. Slip the wire through the main body into the structure, case, or panel. Leave enough slack to make the termination inside the structure, case, or panel. 3. Slide the outer protective nut into the main gland body attached to the barrier, tightening the two halves. Ensure the outer protective nut makes contact with the entry nut screwed to the structure, panel, or case body. This will ensure the clamping ring makes positive contact with the cable. 4. Give a 1/4 turn with the crescent wrench at all connection points, ensuring proper tightening. Do not over-tighten.
You should use an RG-6 cable RG-6 A type of coaxial cable with an impedance of 75 ohms and that contains an 18 AWG core conductor. RG-6 is used for television, satellite, and broadband cable connections. Source = Network+ Guide to Networks (Fifth Edition) by Tamara Dean
To determine the cable size in mm2 required for 450 amps, you need to consider the current-carrying capacity of the cable. The exact size will depend on the type of cable and the installation conditions. For 450 amps, heavy-duty cables with a size of around 240 mm2 or larger would typically be used to ensure safe and efficient operation.
