I read 314.4 which was relatively vague, and 314.40 (D) which also was not specific. First of all, an isolated ground circuit is of little use. According to the IEEE, the results range from no effect to worse. The NEC does not require an isolated ground but allows it. Perhaps when we had computers that were networked with RG59 or RS232, the ground issues were signficant. Now with CAT 5 type wiring, its just not an issue.Ground Test Box refer to a junction box used for test, isolated ground and connect between ground wire and the other system such as lightning protection system, surge protection system, Power-electrical grounding system, Data grounding system, Communications grounding system, Signal grounding system, etc. There are 3 type of Ground Test Box .
A dedicated circuit means it is hard-wired to a single appliance (e.g. dishwasher) or has a single outlet (most motors that "plug in" such as a fridge). I have a junction box in the basement with two circuits passing through it, one of which is for the washing machine. That is still a dedicated motor circuit. –
receptacle screw or metal junction box, and re-insert the SureTest into the receptacle and record the ohms value. The isolated ground adapter creates a parallel pathway to ground, which results in a lower ground impedance reading with the adapter versus with the receptacle with the isolated ground.
