So I have a static caravan that has a hookup to the house, And I wanted to improve the earthing by installing one specifically just for the caravan,

So I have driven in around 4ft of copper pipe and used 30a capble to earth both the chassis of the caravan and the metal exterior, but upon checking the continuity and resistance the earting I have installed seems to have increased the resistance, Measuring with my new earth disconnected from the ground rod it measures 30 Ohms from an earth in a socket to the the caravan shell / exterior sheeting, with my new earth rod connected it measures 60 Ohms, now the hook-up runs around 15 metres to the garage and then into the house.

If electricity follows the path of least resistance than surely my readings must be wrong, right?

I don't have any fancy earth testing equipment just a multimeter, I'm not an electrician, I just wanted to improve the earth in the caravan mainly to add additional safety and protection from lightning / EMP.


Either there is a principle I am yet to understand or I am measuring it wrong, or have faulty reading, what do you guys think, and what should a good earth measure in Ohms or isnt it that simple, It's very strange because I added salt and water around the earth rod to check it and the resistance went from 60 Ohms to around 55 Ohms.

what a load of old bolloks this is....
go get an electrician in will you.....lol....lol...
honestly, this kind of post is just asking for it....
