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.
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.
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.
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.
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.

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.
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.
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
To wire low voltage landscape lighting effectively, follow these steps: Plan your layout and determine the locations for the lights. Choose the appropriate low voltage transformer based on the total wattage of your lights. Lay out the cable along the planned path, leaving extra cable at each light location. Connect the cable to the transformer, making sure to match the polarity. Connect the lights to the cable, ensuring a secure and weatherproof connection. Test the system to ensure all lights are working properly before burying the cable.

To wire low voltage lighting for your outdoor landscape, first plan the layout and determine the locations for the lights. Next, bury the low voltage cable in the ground, making sure to leave extra cable at each light location. Connect the cable to a transformer, which converts standard household voltage to low voltage. Finally, connect the lights to the cable using wire connectors, following the manufacturer's instructions. Test the system to ensure proper functioning before burying the cable completely.

Primary : 4 Secondary : 3/0 <<>> To answer this question correctly a voltage must be stated.
To properly wire low voltage lights in your outdoor landscape, you should first plan the layout of your lights and determine the appropriate transformer size. Next, bury the low voltage cable at least 6 inches deep and connect it to the transformer. Then, connect the lights to the cable using waterproof wire connectors. Finally, test the system to ensure all lights are working properly and adjust as needed.
