Ensure Your Tools are Functional

When it comes to working on your homes electricity, a multi tester is going to be your best friend and your go to tool for ensuring safe working conditions. But, before you place your trust in this instrument, you need to make sure it is working properly. Do this by using it to test a circuit that you already know is working, like a receptacle in another room. Since digital multi testers use batteries, performing this test will let you know that the battery is good and the tester is working.
You should also only use insulated screwdrivers when working on electrical circuits. These screwdrivers have insulated handles and shafts that help prevent accidental shorts.
