Hi guys


Came to do the testing on small bathroom lighting job today and I was confronted with this old piece of scrap iron.

I’ve never come across one of these before, so I’m asking you guys for confirmation of what I think what it is I’m looking for the type and BS number and amperage, so I can fill out my certificate, my thoughts are it’s a Bs 3036 semi enclosed rewire able fuses and guessing the fuse wire has been upgraded in the past from 30 amp to probably 60 amp.

I’ve already told my customer that they need to contact Electricity North West to have the head unit replaced as soon as possible for two reasons, the Bitumen has tracked back into the head and the live fuse is fully enclosed in the bitumen at the bottom and cannot be removed and the second reason it’s a fused neutral supply that’s no longer allowed be installed.

It isn't always the case it would be a DNO fuse. What do you normally quote for a sealed head.
If the seal has been cut previously by another person I take a look

If it’s sealed it stays sealed and “unknown” is recorded on certificate, I have been question to why I haven’t noted the info on my assessments in the past


If it’s a modern head unit that says 100amp on the side or has Bs1361 on it I record that, or if I know what is normally in the cut out from previous installs I put record an educated guess??

So the same question back at you what do you record on all your certificates you can’t leave them blank on every one,


I posted a picture of a head unit that was similar to this one a couple of months back where the bitumen has seeped out of the old head, when the DNO had been to replace the head with a new unit they didn’t actually put a seal on the fuse, that might have been because the customer had told them I was going to be fitting a new consumer unit a week later and I’d asked the customer to get the DNO to install an isolator switch which they told the customer they don’t do
 
You can't be guessing or noting what the carrier has written on it. Without physically seeing it you must state NV. If anyone queries this tell them the head is not part of your remit to be interfering with. To be honest this info is generally irrelevant.
 
To be fair, if it didn't have a seal then I would have had a little peak. Wouldn't touch though.
I didn’t touch it, as soon as I opened it I saw the asbestos flash mat and the label looked suspiciously like asbestos too took a photo and closed it back up.


I knew straight away it needed replacing because of the fused neutral supply and the bitumen encasing the lower part of the fuse carrier.

I am amazed the guy who did the board change back in 2012 didn’t notify the DNO to get it updated

Fair enough I’ll just put NV from now on, if I get questioned again on my assessment I’ll explain why I’ve noted on the certificate as NV
 
He maybe did notify the dno but because of the daft setup with suppliers chopping and changing things get overlooked..
Also meter readers should be observing and reporting substandard kit..
Any paperwork from the consumer unit change?
Customer didn’t have anything the other day when I asked but was getting onto their solicitor to check why no paperwork was available on purchasing the house

I think solicitors check whether here has been a Part P notification
If there has been a notified job they then request the certification
If no job has been notified no cert request because its a unknown

Part P seems to be irrelevant except when there has been a notification made,no notification no problems are encountered
