I bought one of them Snap Safe hot rods, same concept like the Golden Rod or MAX Safes rod. Only problem is, after I removed the wall outlet from the cable to feed it through the small hole in my safe, I can't remember the orientation of the polarization that I put the cap back onto the cable (i.e., neutral or line out ends on the outlet plug cap in relation to the cable's 2 lines).
How would you know if the rod is working correctly, in terms of the temperature it should be? If it was improperly connected, one might expect a different temperature indicating that a resistive element of some kind is burnt out, or lukewarm/ambient room temperature instead upon touching it...
