Electrical Current Detector
Electrical Current Detector
(OP)
I'm structural so I hope everyone will cut me some slack as far as my terminology goes. My question is: does anyone know of a reliable device that can detect a live electrical wire embedded in some concrete (say, about an inch)?
My situation is: I handle a lot of structural vibration issues......and sometimes I feel the need to drive some concrete/masonry nails into the pedestals, slabs, etc where I take measurements (for accurate measurements). Even though I use very shallow nails (typically about 3/4"), I still worry about frying myself......so any suggestions are welcome. Thanks in advance.

Gardiner Bender market a unit under the name of "Circuit Alert"
This has adjustable sensitivity and on high sensitivity may be able to do your job.
Be aware that those who use "Non-Contact Voltage Sensors" don't trust them completely.
An alert indicates that an electric field is present. No alert does not always mean the absence of potential.
Still a lot better than nothing.
I am not sure but wet concrete may seriously attenuate the sensitivity.
Try one on a known hot wire buried in concrete.
A hot wire in metallic conduit will probably not be detected.
The Tic-Testers are cheap. Probably under $20.
