Review on 🔦 Amprobe VP-440 Non-Contact Voltage Detector - 2734332 by Antonio Liberty

Great voltage tester for inside switch boxes and other electrical work. It detects live 120VAC wires 1/4" to 1/2" through the insulation. This makes it easy to identify hot wires in a crowded electrical box. I've used this a few times now and it seems to be consistent and reliable in identifying hot wires without false alarms. Some users expect this type of device to detect live wires several inches away - it WILL NOT, and it does exactly that . so useful to me. I bought a similar device from Lowes which detects DID voltage at 4 or 5 inches which makes it useless to work in a switch box. Every wire shows "hot" because you don't get the probe far can move enough wire in the box.
