If working with live wires, do the whole thing standing on a wooden stool. You must have a thick insulator between you and ground. You will probably touch a live wire at some point, and the size of shock you get depends on how well insulated you are from the ground, walls, and other objects around you.
Don't bother wrapping wires around you.
If you connect the live to the earth wire, you will blow the fuse, and probably destroy the wires too. Then you'll have to rip out the plaster to lay new wires.
This is not difficult if you are careful, not tired, and have good common sense.
Wrap the live in electrical tape first. Only unwrap it for the few seconds where you are putting it into its connector. That's the only step you need to do carefully.
