How to Find a Good Earth Ground The servicing of these boards requires special precautions. It is 1)A cold-water pipe is a guaranteed earth ground; the cover-plate strongly recommended to use Lead Free Solder material in order to retaining screw on most AC outlet boxes is also at earth ground. guarantee optimal quality of new solder joints. 2)If the retaining screw is to be used as your earth ground, verify that it is at ground by measuring the resistance between it and a cold-water pipe with an ohmmeter. The reading should be zero ohms. 3)If a cold-water pipe is not accessible, connect a 60- to 100-watt trouble- light (not a neon lamp) between the hot side of the receptacle and the retaining screw. Try both slots, if necessary, to locate the hot side on the line; the lamp should light at normal brilliance if the screw is at ground potential (see Figure 3). Figure 3.
