I believe someone called out a BG screefix special cu earlier in the thread?
What do I win?! As is often the way with this type of thread they even left the unused MCBs in place instead of fitting blanks.
It's poor design to put the upstairs sockets and upstairs lights on the same RCD, and the same downstairs. Then again it's poor using a dual RCD consumer unit. With the Price of RCBOs being so low now I haven't fitted a dual RCD consumer unit in a very long time. It's much more convenient for the customer to lose 1 circuit during a fault, rather than half the house.
I don't see any AFDDs there so I'm not sure why the AFDD test button box has been ticked.
Again, there are only 2 RCDs to test so no reason not to fill in the tripping times, N/A is not a suitable entry.
He hasn't filled in what number of live conductors there are, again entering N/A. The supply fuse is unlikely to have a breaking capacity of 100KA. The main switch is a 60947-3 not 60947 type b (whatever that is). He has put N/A for earthing conductor and bonding conductor continuity checks, both types of conductor are present so they should have been checked and both boxes ticked.
He has ticked that he has checked parallel or switched alternative sources of supply, yet this installation has neither.
He has ticked that he has checked prosumer's electrical installation, again this doesn't apply to this installation.
He has ticked that he has checked a number of different items in the Essential Tests section several there will not be applicable and several he has ticked as carried out have no results entered in the schedule of test results section.
The certificate is pretty much worthless (except as evidence in court!)
Can I kick off with a design question? What do we think about 20A for the kitchen with no separate appliance circuit(s)?
Think of all the money saved in cable by not connecting the last socket back to the MCB! I would be OK with the house sockets being on 20A, but the kitchen would be pushing it, unless it only has 1 large appliance.
As there are no ring finals that also means a lot less tests need to be carried out, so no excuses for not doing insulation resistance and RCD tests.
