Does it work to check a 480 volt wire?

Use CAUTION!!! This unit is NOT designed to be used on LIVE ELECTRICAL CIRCUITS! Disconnect power from the line you want to trace. It should work fine for it's intended purpose, to trace wires! Use an appropriate Volt meter to trace live circuits. If you are not experienced/qualified to work on High Voltage circuits you should leave that work to someone who is. 480 volts will likely kill you if you make the mistake of being a circuit element! This is no joking matter! Be careful!

I have a dc wire at switch in my rv. switch has power. the wires goes to somewhere in ceiling but not to a fixture. ie wire just ends. will this work?

Yes, this would work. However, this unit this unit has a weak signal strength, meaning that as you trace a wire the signal sound fades away. Let's say you have 20 ft. of hidden wire. One end starts in a light switch box and the other end is unknown. As you begin to trace the wire the signal sound goes away before you get to the other end of the wire. There are better devices out there. I wouldn't buy this one again.

Can this be used for a single wire, or do I have to have two to connect to?

Thanks for the great question. It will work for a single wire, depending on what you need to do. Please write us at care@truetosource.co with more info and we will help you out. Warmest regards, TrueToSource Customer Care

Can I use this to trace 12v dc wiring on a boat?

I don't see why not. I used it to successfully trace and locate 12v DC speaker wires (approximately 16 gauge) in a medium sized building. Make sure your Sounder is active before you start tracing.
