Circuit Alert Voltage Sensing Wire Stripper

Gardner Bender’s Circuit Alert wire strippers help you avoid shocking situations by sensing and alerting you to active voltage before you strip.  Just slide the switch to “on,” and as you move the sensor’s handle toward a circuit, the strippers beep and flash if it’s live. 

The only difference between the two models Gardner offers is that the GST-55 strips #10-18 AWG stranded or solid wire while the GST-224 strips #12-2 and #14-2 non-metallic sheath cable.  Both wire strippers cut and re-thread common-sized electrical screws as well, and both strippers include special holes for creating wire loops.  The blades are stainless steel and the handles are polycarbonate thermoplastic and over-molded rubber.

Gardner Bender claims these wire strippers can withstand a 12′ drop onto concrete.  They’d better be built to last, as street pricing starts around $25 — quite a bit for a pair of wire strippers.

    I always imagined these would use the metal end to detect the current, not the handle end. So, you still have to remember to check before actually doing anything. But, I guess there is benefit in using a single tool. Also, even though it has electronics, 12′ doesn’t seem like very much, not that I typically work with electricity above that height.

    Neat gadget but, I thought this was why electricians had apprentices.

    electrician: Hand me one of those two wires.

    apprentice: Which one?

    electrician; Doesn’t matter.

    apprentice: Uh, OK. Anything else?

    electrician: No, but whatever you do, don’t touch that other wire.

    I have had one of these for about six months now, and it’s the worst non-contact tester I’ve ever used. Any flourescent light within 5 feet will set it off, and it occasionally doesn’t register live wires at all unless I touch them just right with it.

    It’s still great for stripping romex, but I don’t use the tester anymore, because a tester like this that you can’t trust is worse than no tester at all.

    As is often the case, real world use doesn’t live up to the advertisements. Thanks Joe, saved me a few bucks finding out myself.
