Dimmers that don’t have a off switch will let electricity pass through. Some testers pick up low voltage amounts. Not enough to shock but enough tester show electricity is there. Buy a tester with sensitive adjustment . **Q: Will this differentiate between cirucuts with no voltage on the breaker board in a house?** A: Of course it will. If there is no voltage reading at the input of the breaker, there is no voltage at the breaker. To check if voltage is coming to the box, check the main breaker. If there is no voltage at the supply side of the main house breaker, check the meter supplying voltage to the house. Check each breaker to isolate. Truthfully, I don't understand your question. It's a voltage detector and you are the operator. **Q: Battery easily changed on this unit? How...screw cap? My old Fluke is impossible to change battery so waste of money.** A: The rear of the unit, (the bigger torch) has a cap that unscrews fairly easily. This unit also has a self test that means the unit will automatically shut off on startup if the battery level is too low. **Q: automobile voltage?** A: For electrical house voltage ## Frequently Bought Together - Southwire 40150N Advanced AC Non Contact Voltage Tester Pen; Dual Range 12-1000VAC/100-1000VAC; Non Contact Voltage Detector with LED Flashlight; 6' drop test rated; and IP67 waterproof; NCVT - Klein Tools RT250 GFCI Outlet Tester with LCD Display, Electric Voltage Tester for Standard 3-Wire 120V Electrical Receptacles - Klein Tools 80016 Circuit Breaker Finder Tool Kit with Accessories, 2-Piece Set, Includes Cat.
