With the new TREC SOP in effect as of 2/1/2009 all Texas HI’s are required to Report as Deficient “appliances and metal pipes that are not bonded or grounded”. With that in mind, I wanted a simple method of testing the various appliances (stove, vent hood, furnace, etc) for proper grounding. I have designed and built a prototype for a tester that should work just fine. It consists of a main body with batteries & LED, a 3-pronged power plug to access Ground and a test probe with an audible tone generator for easy confirmation of ground continuity to the appliance. To use it, the power cord is plugged into a nearby outlet and the probe is touched to an exposed metal part, i.e a screw, of the appliance. If the appliance is properly grounded then the LED will light and the tone will sound.
I plan to offer this device to other Texas HI’s that need one and I will probably have 3 versions. One, a parts list and basic assembly instructions, Two, a kit containing all the needed parts for the HI to assemble himself (soldering is required) and Three, a completely assembled and tested unit.
