Why is mains electricity dangerous?
because your body is controlled by electric impulses that are far weaker. Mains power can knock your bodys signals out, causing your heart to stop pumping.
What are electrical rising mains?
The rising mains are essentially used in electrical distribution system in buildings two storied and above. It is basically used in indoor applications. Nowadays vertical type distribution is normally used as it is more convenient and reliable compared to rising cable system.
Why is it dangerous to pass to much current through the mains cable?
Current or AMPS are what the appliance draws or load of the appliance. So, if you have a say 10,000 amps going thru a cable rated for say 1,000 amps , guess what ,the cable over heats and either will melt or at least catch fire.
How do you replace 120 volt pool light with a 12 volt pool light?
Answer for countries in Europe and other world areas running a 50 Hz power supply service. This depends on the the light or globe, if you can replace just the globe its very simple. change over the globe and buy yourself a mains(230v or 115v) to 12v isolation transformer, and attach that to the mains cable and run a cable from the 12v to the globe and away you go. The description of how to change the mains to 12v is the same if you have to replace the whole light. Then you just have to replace the globe or the whole light assembly.

· A power cord, line cord or mains cable is known as the supply cable, which temporarily connects an appliance to the mains electricity supply to a wall socket. · A supply cable connects the refrigerator to the mains electricity supply via a wall socket.
Why is dangerous to pass too much current through a mains cable?
Passing too much current through a mains cable can lead to overheating, which can result in the insulation melting and causing a short circuit. This can pose a fire hazard and increase the risk of electric shocks. Additionally, exceeding the current-carrying capacity of the cable can damage the electrical components connected to it.

What is a ring circuit?
Usually,there are many mains sockets in a flat to provide electricity for electrical appliances.Do you know how these mains sockets are connected to the electric cable that carries electricity to the flat? The electric cable that carries electricity to a flat is connected to the consumer unit.In the consumer unit,the electric cable branches into a number of parallel circuits that deliver electricity to ceiling lamps,mains sockets,air conditioners(or other appliances with high working current),etc.The circuit that delivers electricity to main sockets exists in form of a ring and is therefore called a ring circuit. The ring circuit provides two paths for electric current to flow from the consumer unit to the mmain sockets.Each path only carries half of the electric current.Therefore,the chance of overloading the circuit is reduced.Besides,if one of the paths is damaged,there's still another path for carrying electric current.
