Clamp meter

A clamp meter is a special tool that helps electrical workers to check how much electric power is running through a wire, without having to cut the wire or touch it directly. It looks like a regular pair of pliers, but it has a special part that can open up and clamp around a wire. The clamp measures the magnetic field around the wire, which tells the worker how much power is flowing through it. The workers can use this information to make sure that everything is working correctly and safely. Think of it like a tire pressure gauge, but instead of checking air pressure, it checks electric power!
