Question

Electrical wires sometimes have a plastic coating wrapped around them. How does this make the wires safer to handle

Answer 1

When the wires are hot or active then the signal isn't short circuited when grabbing them. They will also prevent short circuiting with anything else

Answer 2

Plastic coating around electric wires are for safe use because plastic is an insulator and does not allow the current to flow.
