Mains live and neutral taped together.

Hi guys,
I have what may seem a very stupid question, but I'm obviously not going to do it
If an appliance has been removed, I know that the wires should be taped up for safety, but what happens if the live and neutral are taped together to form a circuit?
Does it form a complete circuit and simply act as a constant draw on the supply or does it blow the circuit breaker?

It will trip the breaker due to an overload.

It forms a complete circuit, what is called a short circuit. Do not try it.

Yes it acts as a draw, but with a tremendous amount of current. It will almost always trip the breaker which it should do very quickly. It may damage the breaker, and could start a fire if it did not trip a defective breaker.
Stick to your lawn watering schedule until it really starts to pour. After the storm you have only the same number of rest days you always had and then you need to start watering again.
