shocking earth

HI all
i'm doing a little re wiring to a workshop and after running a new earth cable to earthing rod i was getting a tingle, I have a circuit tester that just has some led lights 400v, 240v, 110v ohms etc,

The situation inside is a split with the downstairs being a workshop and the upstairs being a self contained flat,
there is a professional installed consumer unit upstairs, which all looks neat,


I've disconnected the workshop and just connected the flat to the double pole rcd (really old), run the upstairs earth to the new consumer unit in the workshop

Touching the end of the earth cable and the rod the 240v led glows. :unsure:

bridging the meter between the earth and neutral gives a 240 reading as well,


erm.... help :confused:

just to be clear "earth leakage" is ?

Its the point were if you don't know what it is already you definitely need an electrician.
It is where a small current leaks to the earth from an appliance which is acceptable, within reason.

It sounds like you are re-routing the earth from the upstairs flat to an earth in a CU that you have disconnected.

An earth rod may not be adequate to provide a safe effective earth.

If there are people in that flat your actions may have put them at risk of serious, possibly fatal, electric shocks.

the earth from upstairs goes to the new CU, and the new CU in workshop is grounded
