Suppose, the electric circuit is not functioning correctly and you need to fix it. You cannot just open the electrical box and start handling the wires. Electric work is very dangerous and thus, requires precaution. The best way is to use a voltage detector. Turn off the main power and before you start dealing with the circuit, use the voltage detector to ensure that the power has been cut off and it is safe to fix the problem.
Following are the 10 best voltage detectors that you can choose from,
10. Amprobe TIC 300 PRO High Voltage Detector ($185.94)
