Nobody wants to work around hot wires. But, sometimes it’s hard to tell if the power is on or the current has been shut off at the box. The multimeter solves this problem. It gives you peace of mind and keeps you and your crew safe.
If you don’t have a multimeter, you should seriously consider adding one to your box. They’re small, lightweight, and won’t set you back an arm and a leg. If you don’t have one, you really should read up on how to treat electric shock because you just might need to know this information in the future.
Multimeters are simple devices designed to test electrical current. They consist of a positive and a negative lead connected to a measuring device. These amazing machines can not only tell you if electricity is present, but they can also identify the amperage, voltage, and many other important details about the current you are testing. In fact, they are the best way to discover if your wiring has a grounding problem.
Everyone working on a construction site should at least have access to a multimeter and know how to use it. They save time, and they save lives.
