Hi - I've always wondered about this - if the main breaker is off, is there a non-contact tester I can use to see if the wires from the street are live or not? (without turning on the breaker) Thanks!

Guys - what I am trying to test was the main 240V cable going into the breaker box, while the breaker box is off - I've found the pencil testers don't work in this case. Thanks!
