Review on ⚡️ Versatile Voltage Detector: 5 to 1000VAC, 5 In. L - Reliable Testing Tool for Electrical Applications by Jake Solorzano

I had a broken wire in my house which put out 4 lights and 6 outlets even though the circuit breaker didn't turn off. Standard troubleshooting practice in this situation is to first check to see if the ground fault breaker has tripped. No, not this scheme. The next step is to look for problems in the switches, outlets, and light boxes closest to the circuit board, particularly at the border between working and non-working outlets. All electrical appliances were fine. I hate the next step - going into the attic and looking for a way out. That's where this tool comes in very handy. I was able to trace the wires from the control panel to the attic through the horn as I routed them along the wires. I reached the junction box under insulation and the unit squeaked on the wires going into the box and stopped beeping when the wires came out of the box. I turned off the circuit breaker and pulled all the wires out of the junction box to find a broken hot wire. It broke because the bending radius of the wire was too small. You can also use the tool to find a gap in the Christmas lights.
