Formula for working out cable size?
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.
What is the cable size for 7.5 kw 3 phase motor?
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.
What core type and shell type?
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.
Low voltage cable size calculation formula?
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
What is NM cable type?
The NM represents the type of sheath on the cable. NM stands for Non Metallic sheath cable..
Which cable type has a glass or plastic core?
Fiber-optic.
How can you select cable gland for a 240 sqmm cable?
It depends to Overall Diameter, type of armor, Lead Cover and voltage grade.
What cable type usually includes a solid plastic core?
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.

Why cable glands are used?
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.
When and what condition using 1 X 4 core PVC cable and 4 x 1 core PVC cable?
PVC is polyvinyl chloride. It is a very durable and thick type of plastic. It is used often for home piping and irrigation.
What type of gland is the sweat gland?
the merocrine
How do you size a fuse?
The fuse protects the cable it is feeding therefore in UK upto 10A for 1.0mm cable, upto 15A for 1.5mm cable and upto 20A for 2.5mm cable. This is for installation type (solid core copper) cable not flex. In the UK and the rest of the EU (230V) 1 Kw load = 4A so 5A fuse should be OK. 2KW = 8A, 3KW = 12A so use 13A Fuse.
Less numerous type of perspiration-producing gland found mainly in the pubic axillary?
The type of gland that produces perspiration is called an exocrine gland.
What type of cable is an cable modem used for?
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
What is cable size for ceiling fan?
A #14 copper conductor will do very nicely for this type of project.
Is stacking of cables in cable tray permitted?
See NEC Article 392. It depends on the voltage, conductor size and the type of cable tray selected.
