Hello Everyone. I'm surprised this subject does not get much attention. 'The elephant in the room' I refer to is the 'new rubber'.
On new appliances I buy the flex / cable sheathing is far stiffer than stuff I bought say 10 years ago. Also the so-called 'rubberised' extension sockets are...
I need to fit compressible rubber or neoprene gaskets between 12 Hager 2 gang stainless steel flat sockets. The gaskets are needed because the wall has small marble mosaic tiles that have slight unevenness and grout indentations and I would like to minimise risk of water ingress. Must look...
I am doing a non-compliance document for college. I have to find non-compliances whilst on site. I have seen an Intruder Alarm where the PVC Flexible cable is brought through bare metal, so no grommet is fitted. Can anyone tell me what part of BS7671 this would fall under and the definition, please?
testing a property there, the sockets were wired in black rubber 2 core with bare stranded earth coming into the boxes. Done all the Ring tests and everything was fine, continuity between all conductors and R1+R2 fine also. Just wondering is it safe because you got the 2 core cable without a cpc...
Came across an old lighting cable on top some cupboard wall units. cable was live, wrapped in tape then stuffed in an old rubber glove! Got to love the things you find house bashing.
I sent it in to professional electrician magazine for the caught on camera as it made me chuckle too!
Anybody...
Had DB changed a couple of years back in my house that I was renting that I now live in. I was out of the country at the time. No certs were handed over and I am unable to get in contact with the guy that my parents got to do the work. I am in the process of selling the house.

Hi All,
Just looking for some advice, had a new CU fitted and the installer incorrectly drilled a cable access hole in the side of the CU. Once he noticed the mistake he just fitted a rubber closed grommet.
I'm a little unsure if this meets the requirements as surely the whole point of the...
Can anyone point me in the right direction.

Two years ago I installed some garden lighting, using u/g SWA to Wiska boxes, then 3-core 0.75mm rubber flex downleads from each LED fitting.
This week the 30mA RCBO kept tripping. I assumed a luminaire fault, or moisture in a Wiska box, but no. It was leakage across all three cores of one 10m...
Anyone know of any information out their on the current caring capacity of old VIR cables, looks like they are between 16mm-25mm, so any info on the older imperial sizes would be useful
Thanks

Hi Chaps
Been googling away but can't find what I'm looking for :-(
I'm hoping someone could advise please, ideally online somewhere?
I've eventually run out of my supply of P-clip/ loops 'not too sure of the technical name.'

Good night/evening/afternoon/morning, forum members.
I was wondering what makes rubber a good insulator. I understand less dense materials make better insulators, as insulators absorb/trap heat. But I want to know why rubber is a good insulator.
For example, wood makes a good insulator due to...
I'm currently working in a school following up on an insurance report and for the 2nd year running the guy that conducts the report has noted that the fused spurs for some of the hand dryers slide on the tiled finish of the toilet walls when you apply a little pressure.
I believe the...
Hi guys,
after a bit of advice from the more experienced guys if poss.
My neighbour wants a consumer unit change, but the cables are rubber and metal light fittings. I have recommended a rewire but it has fell on deaf ears. I am just wondering who would carry on with a change of consumer unit...
Hi guys,
A customer wants an old re-wireable consumer unit upgraded.
Wiring is extremely old probably 1940's. Of the two power circuits, one is the old rubber cable and one is the old red and black stranded cable.
IR tests show ok L-N L-E N-E.
Problem is the cables have no cpc on the...
