How can you lay earthing strip on cable tray?
no use laying an earthing strip in a cable tray better tap both the ends of the earthing wire to the trunking,it will save your wire also,or lay out a cable in the other trunking where you have low voltage wire running in.
What does the terminology - radial feed - mean in relationship to transformers?
This terminology usually refers to pad mounted transformers. A "radial feed " transformer is a transformer that has one bushing for the high voltage cable line. The high voltage cable terminates into the transformer through the transformer's bushing. There is no second bushing for the high voltage cable to continue further down the line. This type of transformer is usually on the end of a loop feed circuit. This is different from a "loop feed" transformer whose incoming cables are terminated at the primary bushings. On this type of transformer there is a second bushing which connects to the outgoing primary voltage cables that allows the primary to feed another transformer. Each pad mount transformer's secondary feed usually supplies enough power to connect up to four homes.
Why use 16mm cable for earthing?
A large cable for earthing is to allow for the possibility of a very large current which would melt a smaller one thus removing the protection it is supposed to provide.
What thickness cable require for 415 volt?
Voltage determines a cable's insulation thickness, not its conductor thickness (or, more accurately, its cross-sectional area). It's current that determines the csa of a conductor, not voltage.
What device is used to increase or decrease the voltage of an alternating current?
A transformer is the device used to increase or decrease the voltage of alternating current (AC) This is done through a process referred to as inducing.It's operation is based on the fact that electricity produces a magnetic field around itself. By placing 2 coils of cable beside each other, the magnetic field of one coil will induce a voltage in the other coil.

What size of cable wire used for 500 kva transformer 240 volt 3 phase?
A 10 mm cable is most commonly used for a 500 KVA transformer, 240 volt, 3 phrase. The size of the wire that is used in a transformer is based on the voltage.
What is the cable size of 1600kVA transformer?
Cable size is determined by current. You did not provide the current, nor did you include the voltage so that we could calculate the current. Please restate the question, and include either the current or the voltage.
What is a main distributors service cable and what is it connected to when first enering a build?
The main supply will first come from the power company to a transformer to reduce the voltage then from the transformer to the weatherhead then through the house meter to the main disconnect on the outside of building then to the switchgears main. The cable coming from the transformer to the meter and to the top of the main disconnect is the Main service cable

Wire size for a 15 KVA transformer?
Primary : 4 Secondary : 3/0 <<>> To answer this question correctly a voltage must be stated.
If you plug in a Wii console without a transformer for the voltage will you break it?
It's a likely possibility. I would not recommend doing so. It is cheaper to replace a cable than the whole system.

What is the ratings for a pole fuse?
There are two types of pole-mounted fuse. One type is a high-voltage fuse, intended to protect the transformer. The other type is a low-voltage fuse, intended to protect the cable or line supplied by the secondary winding of that transformer. The current ratings of these fuses depend entirely on the current ratings of the devices they are there to protect.
