Non contact Voltmeter
I'm looking for a volt meter that I can use to check DC voltage without cutting into the wire. I know that there is one for AC,but,is there one for DC? Any suggestions?

What you are looking for is not possible. Voltage is by definition measured across two points; it has no meaning at one point. Current, on the other hand, is a measure of electron flow past a point, usually in a wire, of course. Thus, there are many AC or DC current probes that attach to a single point on a wire, but no single point voltage probes.
