| minimum grounding rod depth for outside ESD work? |

So if you are the type of person that likes to work outside, say in a remote gazebo or something on a nice day, where you might not have power available or feel like running a cord, What would be suitable for ESD ground for a wrist strap and ESD mat? The idea being embedded systems development/programming/debugging (with portable logic analyzer). Maybe even soldering if you have a battery iron like the new milwakee one for bigger stuff, but in most cases for soldering you would run a cord.. (i like doing small drill press work outside on summer days). Though it is appealing to try to get like 200W of panels to make a outdoors solder area. |

The solution for grounding an entire house would be a cheap and easy approach... That is, just sink a grounding rod, at the base of the structure... You will need the rod, a wire clamp and wire. Cap a length of pipe, slip the pipe over the rod and drive the rod in, by ramming the pipe down on the rod. Tie the wire to your ESD distribution system, which you can DIY as well. The ESD system should include a 1M resistor. You can search for these circuits. https://www.lowes.com/pd/Galvan-0-625-in-x-8-ft-Copper-Grounding-Rods/3446270 |

no you misunderstood I mean minimum length that will work for ESD protection without having to beat a 8 foot rod or carry 8 foot rod with you. I believe a army munitions disposal video had the answer I am looking for now that I thought about it hard (for grounding the shells in a field location during disassembly). |

I thought basic law of electronics still applicable, it depends on the soil's conductivity isn't it ? A wet swamp definitely differs much compared to say dry desert soil. Measurement tool like megger (earth & resistance meter) supposed to tell you how deep is "enough". cmiiw |

no it is I just never thought home grounding is an issue since you connect with a 1 meg resistor anyway, so it might be overkill |
