Home Depot has provided a list of four easy-to-use electrical tools that can be easily used for basic DIY electrical tasks. These tools can test for voltage, ensure wiring is connected to new outlets correctly, and monitor temperatures without contact to check components for overheating. The Klein Tools NCVT3P, a digital dual-range non-contact voltage tester with an integrated LED flashlight, detects the presence of alternating current (AC) ranging from 12 to 1,000 volts or 70 to 1000 volts. The Milwaukee digital GFCI receptacle tester, priced at $26.97, has a 4.7-star rating across 70 reviews and comes with two AAA batteries. Home Depot also offers several versions from Klein and other brands. Once installed a new outlet in a home or shop, it's often a good idea to test it before plugging in something expensive. The proper set of hand tools is also a must for DIY electrical work, although they're often among the most underrated tools for wiring jobs.
