The original and still the best, Volt Stick is an instant tester
for safely checking the presence of an AC voltage, without making
any disconnections in cables, wall sockets, fuses, circuit breakers,
junction boxes, etc. No current flow is needed for correct operation.
The red indicator in the tip will illuminate on detection of AC
voltage simply by applying the tip close to any connection point,
or moving it along any insulated cable. |
