New circuits. Ra of 229 Ohms therefore the rcds are for fault protection by design. Zdb of 0.29 (10mm gas bond) so are the rcds classed as additional protection?
 
The "advisory" range for TT RA is up to 200 ......... could you add a 2nd rod? (or water the ground?;))
 
Put water with it...reminds me of a long time ago a team were putting in a gigantic earth rod. We used to put loads of salt and coke in the earth and then water it. We dug out the earth before hand and mixed it. One of the guys toward the end jumped on the "conditioned" patch and disappeared into the ground. At the time it was hilarious.
 
Agreed.
Paperwork exercise I suppose, just in case gas gets converted to yellow plastic :)
 
starter for 10.....improve the earthing with more rods or mats.
 
get 1 rod into the foul drain.that should bring the Ra down.:eek::eek::eek:.
 
wait hang on a moment i will be doing more TT jobs in london with the car charger PME situation.
so what do i need for this.. some 12 litre of coke and salt? and this makes the ground soft?
