[QUOTE="Brit90, post: 537840, member: 35930"] Hi, My first post, please be gentle. I am trying to learn about earthing and I am experimenting (safely) about earths. I an a bit confused about earthing right now and I wondered if someone could clear something up. I have installed an earthing rod and I have a machine to test the resistance using the stakes and the results I get are, 85, 88, 84. I have replicated basically what John Ward did in one of his videos about earthing. My confusion now comes with the ohm reading. I thought ohms had to be mainly under 5 ohms (depending on TT TNC etc). Could someone briefly explain how I can get the ohms low enough? There is no bonding to water pipe as it is plastic and no gas in the area. If there are some links or references as well, I would appreciate it. Thank you [/QUOTE]
