tape for probe on flexwatt?

What is the best tape to tape the probe directly to flexwatt? I'm currently using a strip of duct tape cause I was told aluminum foil tape is conductive and no good, but then someone told me again that aluminum foil tape is the best. Please Help! Thanks

Aluminum foil tape is fine as long as it is not touching any live wires. But duct tape works fine as well. You can also use electrical tape (which I personally use). Electrical tape can stand lots of heat and it is easier to peel off if you ever need to.

I use foil tape. No problems
