Getting an electrical shock occurs when you accidentally touch a live conductor. When you do this, the current flows through you and down to the floor. It then goes through the wall through the earth and ends up back in the supply transformer. The current goes back to the supply transformer through one or more of the earth connections that are in the transformer neutral. In effect, you complete the electrical circuit when you touch the live conductor.

It is also important to note that water is an excellent conductor of electricity. Therefore, even more care must be taken when installing wiring in places such as the bathroom where water is commonly used. For this reason, there are a number of special rules for bathrooms that have been established by the Institution of Electrical Engineers. Namely, all metal parts in the bathroom have to be connected with an earth cable.
