What the reg says is that you can fuse it down along the 3M max length or at the end with a FCU, but you still need to fuse it down. The fuse in the plug, if in a spurred socket, is for the cable attached to the plug not the spur cable. Alternatively you can fuse it down on the supply side, eg...
Don't think 3rd party cert active yet, still subject to the framework and paperwork being ratified.
They could however say that they designed it, monitored the work throughout and inspected it, which is a different scenario.
Split the ring into 2 x 20 amp radials on RCBOs, but leave the CPC of both connected together. Meets regs, covers ars. Perhaps as old boys say you coud omit RCD but why bother, leave a smaller blame footprint.
Mr M, Hope you are well. Long time no see.
I think this is what you are thinking of, despite the rambings:
16mm2 tails with a 100a cut out are ok if the MD of the installation(div & load inc) does not exceed the ccc of the tails. 434.5.2 must be met. easy peasy lemon squeezy.
cr.ed.
IR on the ring may be a red herring, if the boiler is on a seperate radial.
However, the boiler is new, so is the fault, and coincidence is not a friend of mine. I would try to eliminate the obvious. The boiler could be triping the RCD even if not fed from it. Usually this is an N to E issue...
May just be a dodgy cooker. I had one straight out of the box with a live wire trapped between two panels once.
If you are careful with the metalwork, as a quick test you could put a plug on the cooker with a 3a or lower fuse if you have one, plug it into an RCD protected socket. If it pops...
O Ohms N to E -
Did you leave the main switch on during the test?
Was there any gear plugged in during the test?
Was there any extension leads, with surge protectors?
Is it possible that it could always happen, but the remotes were oever aimed at the fire, but now the drool or chewing, has scattered the IR over a wider area?
Cover the IR sensor on the fire with a flap of tape so you have to fire it accurately from a close distance.
Getting back to the original post (which probably isn't the main point here now) I am surprised by a lot of the responses here.
A 40 amp cooker? That is maximum theoretical demand, I would be surprised if it had a draw of more than half that for any length of time long enough to cause...
"3 (I think?) rings on the hob work, while the other one doesn't work but when you switch it on all of the power comes back on in the flat. When you turn it off so does all the power in the flat."
This is a joke, surely? Or is it a ring problem ...
