A: If you are trying to identify a specific wire you will need some separation between it and other wires in the same box.

A: i cant find where mine is. the i see on a search that it is imprinted with patent US.

**Q: what is the working voltage range and will it work on DC or just AC?**
A: Just AC. working range is 50 to 1000 VAC.

**Q: Do you have to hold down the button while testing ?**

## Customer Reviews

### ⭐⭐⭐⭐⭐ good great testing device
*by W***E on June 11, 2024*

testing electricty

### ⭐⭐⭐⭐⭐ Electric wire power
*by A***R on May 30, 2024*

Seems to be almost the same as what I thought except these two new ones I bought was not exactly like the old one I had which was presented when I ordered it except these do look heavy duty and does have a light that goes on which is a big plus so yes, I do recommend these electrical power testers

### ⭐⭐⭐⭐ Best greenlee tick tester so far
*by J***P on April 23, 2011*

This is my second GT-12 so far. I used to use the GT-11s and always hated the twist top to turn the tester on, which would eventually fall off. The addition of the push button makes this a much nicer tester. the only complaint i have about these is that the battery cover feels flimsy, you can push on it and feel it slide sideways. My previous GT-12 never lost the cover but it feels like a potential issue for those of us who use these often. The self check is nice however please remember too always test on a known live circuit first to make sure it works.
