a guy at work has asked me what would you do in this situation.
He has a house which is not connected to the mains at all and is run from a generator which has a earth spike.
He has had a couple of sparkies work at his place and when doing the rcd testing their tester showed "no earth" ..
He is an engineer and told them that they should perhaps connect the cpc and neutral together as thats what happens at the transformers on the mains. He asked me what i would do in this situation and i replied that i would have made a point of finding out thru research and possibly a post on a forum. So here i am, is that the correct way to connect the earthing arrangemets at a generator or have his sparkies come up with a fault that needs looking into???
 
as far as i can make out, its using the cable armouring but, as ive not seen the install i cant say for sure . its just a bit of a thought experiment
 
I wouldn't mind betting that whoever put the earth rod, in was happy using a thin twig.
Anyway, without a lot more detailed information on the set up it'll be pointless making assumptions. Save to say this install as it stands should be considered a TT earth system, and no do not make a N-E connection as in a PME/TNC-S, only the generator neutral should be earthed. But again this depends on the type of generator your friend has hooked -up.

So go have a look and come back with some useful information that we can comment advise on.
 
As a general observation, if this house is this guy's normal full time residence, it must be costing him an absolute arm and a leg in running and maintenance costs!! lol!!
 
Many years back I put a 7.5KVA diesel set in for a house in the middle of nowhere. I made a heat exchanger for the exhaust, hot water for the house was a by-product. The cost for a OH 11KV was £47K thirty years ago. It ran on red, so not that expencive.

It was a TN-C system, as you would expect from me.
 
I'd be investing in some decent solar panels as well. Daz
