Proper length and burial of grounding rod. - DoItYourself.com
WebOct 1, 1998 · The effectiveness of grounding rods largely depends on whether the soil surrounding the rods can conduct large electrical currents. To design a buried grounding system correctly, you must measure earth resistivity with a ground resistance testing instrument. This instrument should also have switches to change the resistance range. WebAn effective ground doesn't necessarily need to go deep: it can also go out. Several ground rods, about as far apart as they are deep, connected with 6 AWG solid wire or even better 0.022" solid copper strap will lower the ground impedance by spreading over a larger area. I suspect in Arizona you'd need quite a lot of ground rods to get a good ... genshin unlock tri seal
