What are IEE regulation in wiring?

BS7671:2008 Requirements for Electrical Installations: IEE Wiring Regulations, 17th Edition. Strictly speaking, this document is published by the IET -the Institution of Engineering and Technology, as the IEE (Institution of Electrical Engineers) no longer exists.

What is the difference between thermosetting and thermoplastic cable?

The terms are used to categorise cable insulation according to its properties, such as its operating temperature, rather than the ingredients from which it is are made.These terms are now used by the IEE Wiring Regulations to describe insulation formerly described, for example, as 'pvc' (a 'thermoplastic' material) or rubber ( a 'thermosetting' material).


Calculating appropriate low voltage transformer for outside low voltage lighting?

calculate the total sum of lighting power and add 10% as safe operation of the transformer. then select a transformer for that rating. suppose your total lighting power is 300VA. add 10% of the total lighting power so the total power is 330VA. therefore your transformer size can be 330va or more. please follow IEE regulations.


What is formula for calculate size of cable?

CABLE and WIRE are not the same thing.Cables are sized by the diameter of the longest side (romex isn't round, it's an oval, compared to CAT 5, which is round)Wires are sized based on the type of insulation and gauge of copper.Then you take that info to the code book. A chart tells you the answer. BEWARE: multiple cables or wires in a conduit changes the equation.Whether or not more will fit, the only correct way to size cables or wires is to use the Code Book.For UK InstallationsThis topic is covered in Appendix 5 of the On-Site Guide supplement to BS 7671:2008 Requirements for Electrical Installations (the 'IEE Wiring Regulations'), although this Appendix only relates to the ease with which cables can be drawn in, and does not take into account the effect of 'grouping' (i.e. the effect that the temperature of each conductor will have on the rest). The number of cables permitted depends upon (1) the total cross-sectional area of all the cables drawn in, (2) the length of run, and (3) the presence of bends.The effect of 'grouping' is to reduce the number of cables actually allowed within a conduit (or other enclosure), because, as the number of circuits increases, the current-carrying capacity of the cables reduces. Guidance on this is provided through 'space factor', which is the ratio of the (total csa of all the cables) to (the internal csa of the conduit), expressed as a percentage, with the maximum permissible space factor being 40%. The remaining 60% space is required to allow the dissipation of heat from the cables. (As the first answer indicates, the csa of a flat cable is based on the maximum width of that cable).

How do you get a Qatar electrical license when you need to have that procedure?

Apply for a license from Qatar General Electricity & Water Corporation "KAHRAMAA". It is a test and interview based on the Regulations for the Installation of Electrical Wiring, Electrical Equipment and Air Conditioning equipment. (Based on IEE and BS 7671 ) you can find the regulation, but you have to be in Qatar before applying.See related link below.
