Should a Faraday Cage Be Grounded?

M.D. Creekmore

I've been interested in self-reliance topics for over 25 years. I’m the author of four books that you can find here. Over the years, I’ve learned a lot about prepping, homesteading, and self-reliance topics through first-hand experience and now I want to share what I’ve learned with you.

    My whole life, a good ground was the rule. Be it faulty ground straps to the frame of your old jalopy, a corroded bit of house wiring, trailers, or marine applications, ALWAYS the check the ground first when trouble starts. Now I must clarify something with a question. When watching many of Dr A. Bradley’s YouTubes where he tested various items to see how many dB of protection each offered, he never used a ground wire. Based on this article, am I assuming correctly that Dr Bradley’s tests were just that, a test of the dB reduction of an item but in fact, a solid ground MUST be added to whatever you use as a Faraday cage to ensure full and reliable protection? Dr Bradleys videos seem to infer that grounding is NOT a necessity as long as your cage is properly sealed with conductive tape, etc that allows no leakage into you DIY cage and the contents are electrically insulated from the metal container. Any and all responses are most welcome

    How long? You know, like leakage and dissipation as with battery shelf life. How long before the 100,000kv charge dissipates on it’s own, ’cause the electrons have worn themselves out circling around with nowhere to go, so one at a time have found alternate ways to dissipate their electrical desires?

    I am wondering if it may be wise to wait a couple of days before digging out the backup stuff, after an EMP.

    What do you think about a metal garbage can and metal lid grounded onto radiator pipes?
