earth connection at service cut-out

[maccarooni]

been to look at a job today and the main is earth is connected with the neutral in a henly block. Now although the henly block has a seal on it, is this a legal connection.? theres no supplied earth connector from the dno.

Any thoughts.

depends where the henly is and who put it there. it could have been done by DNO, or could be a DIY PME. could contact DNO and see if they have earthing type on record

I think 'legal' is a bit strong.

However, quite a common occurrence, you don;t always get an actual earth block as the DNO should be called to connect\disconnect tails anyway, which includes the earth. It's up to you to provide the main earth link if you need one.

Doubt it's DIY PME as it wouldn't be sealed.

Thanks for the replies.

So, would this need a code 3 on a pir then ?

 

[Andy™]

is there a PME label anywhere? any chance of a pic?

Why would it need anything?

is the cut-out fuse a small rectangular affair?? if so its not an unusual set-up, but a bit out of date. You could contact Western Power as suggested to establish supply chracteristics, and possibly to come out and have a look - its theirs afterall.

sorry

Didn't get a pic.

the reason i'm asking is (having got my 2391 this year) this is my first ever pir inspection and was hoping to make sure ive covered everything.

generally would take it as granted as a pme with eatrh connected to side of service head and a Ze of .21.

however not generally seen them connected in henlys with a seal, i thought id' ask.

When I worked for the electricity board we would sometimes get called to a property where there was a high Ze. If it was a TNS system we would sometimes temporarily connect N-E until the fault (usually a joint in the road) was fixed. Sounds like this may be something similar.

 

[maccarooni]

Its deffo a pme TN-CS.

by the loks of it it has been there for years. i.ve come across a couple of jobs where someone has definetly made a diy connection, but as said previously, its in a henly and with a seal.

I'm still intrigued as to what you would put down in the comments box on the PIR.

I was asking, in case i should put something there with regards to the earth, being connected with the neutral in a henly block.

unfortunately not all of us have years of pir experience, and a little advice was all i was after.

No problem, was just wondering. I tend not to mention anything about the exact connection methods of the mains supply as it's not up to me to fix it so no need to list it. I'd only mention it if it was a safety issue.

But you do need to put earth system ie TNS, TT or TNCS.

Yeah, I was referring just to the comments there.

Sorry I am getting confused with this I thought the problem was he did not know the earth system.

TBH, I thought that at one point, hence the question about what he would put on the cert. If you don't know the supply type it isn't a fault, it's an omission on the testers part as a call to the DNO should confirm what they are supplying.

but what if it was PME, but changed to TT? DNO wont be able to tell you that (but you should be able to work out that one on your own)
