On a job that a previous spark has been on, rods were linked out so I did them properly now most circuits trip. It's a tt system that the earth is connected to the gas pipe then to the water shocking in itself. There is a short between live and neutral on the feed cable to the cooker but it's only when you turn the cooker on that it trips out.
The feed cable has a fault still when removed from the switch. Cooker cable clear. Connect feed with fault circuit will stay energised connect cooker trips. Not sure how a cooker could be the fault when the fault is present when there disconnected from each other and disconnected at the board
Well according to the nic eic they need to be separate should be continuous and have a reading of less than 0.05. These are one 10mm to the gas a link bond to the main water acting as the main earth to the property all jointed under the floor in a block. It's a new re-wire
If you remove the gas to a new location or the water depending on what's the primary one you could also be removing the earth as well and not know. If there separate and at there correct location this shouldn't happen
You can largely ignore the NICEIC they make their own rules up.AFAIK there has never been a reason not to use one cable to bond gas and water providing it is one continuous cable. That said I did have one prat from them trying to tell me a cable wasn't continuous because it had a crimp lug fitted. Wrong again, if both cables are crimped in the same lug then it is continuous.
It's fine to bond like that, the NIC are fine with it in my experience too. It has to be a continuous run though. You can strip an inch of insulation and loop the cable, or place the two ends in a single lug.
ive always understood it was, and i used be an inspector for eastern leccy. surely common sense would indicate this. We would fail it if not continuas.
Then you would be wrong to fail it ( by fail It I take it you mean unsatisfactory). There is no regulation stipulating it has to be continuous only guidance. Obviously in an ideal world it would be continuous but would be wrong to produce an unsatisfactory report based on the fact its not continuous.
Show the regulation then. Or is eastern leccy like the NIC, make the rules up as you go along. There's no wonder I fall out with muppets.
Im talkin about the 80s! We were installation inspectors, we would give it the once over ,including bonding done correctly as per electricity board policy, then a megger test. if it passed we would carry out connection of new wiring to the meters.was just doing as i was told.whats the problem with doing as one continuose run if bable run permits?
Bable, it bomes as reels of bable. 2.5mm bable is often used for socket bircuits. You would have learnt that if you had gone to bollege.
I post on topics that interest me. TEF have given me the resources to resurrect all the theory and practice stuff from EB, a not inconsiderable task given the damage done to the articles. 18 months so far and I’m finally getting on top of it.
