no earth rod in tt system

once youve done work on a few TT places, youll soon find out its not much harder than TN supplies

[SPECIAL LOCATION]

Not done any tests but I inspected the 2 fuse box's and there is no main earthing at all. All the cpc's from each circuit coming into the fuse box just connect to the external metal fuse box unit, there is no earth bars or anything. I have not long been in this game and this is my first tt system I have seen due to me working in a busy built up area. I have walked around the outside of the property with the owner and there is no sign at all of the rod location. Is it a common situation to find there is no earth rod's in tt systems?

1. Its not unusual to find an old earth rod has been buried under a tarmac or block paving driveway....

just the remnants of an old 4.0mm or 6.0mm wire appearing out of nowhere.

2. Have you actual taken any earth loop readings?

I personally would want to find out if there is any electrical earth connection....

even if you cant see one!?

Don't forget earth cable maybe black in colour or just bare wire - made the mistake once of thinking a house had no earthing on lighting - it was bare stranded wire, which I realised was there after I started re-wiring BlushingBlushingBlushing. Never seen that set-up before or since.

the bare wire is still no good on lighting. seen it a few times on houses ive re-wired. the joints are all twisted, no connectors or anything

What do you mean by the external metal fuse box unit? Are you implying that the CPCs end up connecting to the cast-iron cut-out? It may be the case that you have a TN-S supply at the cut-out.

every rod ive installed indoors has always had a decent reading (less than 100). but its often only a few metres to 'outside'

surely if you install a rod indoors you are penetrating the damp proof course which will cause no end of problems.

In a modern house you would,,, but Visqueen wasn't about in Victorian days and they relied on the DPC in the walls

ala floating floors with airbricks

i assume you have never been in the real world, where you take a floor board up and its soil under it?

 

[binky]

indoor rods tend to suffer from drier ground and higher resistances from what I've seen of them. Either that or solid concrete floors :slap
