SAFETY NOTES

1-7. How to Find a Good Earth Ground.

1) A cold-water pipe is a guaranteed earth ground; the cover-plate retaining screw on

most AC outlet boxes is also at earth ground.

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).

The servicing of these boards requires special precautions. It is strongly recommended to use

Lead Free Solder material in order to guarantee optimal quality of new solder joints.
