    Question regarding signing off 32a ring circuit with broken CPC ring continuity

    I installed a kitchen ring recently. Went back to test after the builders had finished and found that the CPC is broken somewhere inaccessible, everything else tests normal. I’ve got continuity on live conductors, and even with the broken CPC, each socket is connected to the CPC and tests with...

    Single phase appliance from a 32a 5 pin trailing socket

    Hi all What are the thoughts on fitting a male 5 pin plug to a single phase appliance then connecting it to a 5 pin three phase socket. Obviously only using one phase. Rough but as a temporary measure is it against the regulations? Found these distribution boxes which appear to do similar...

    Ax disconnection times 32A+

    I don't know why I've not noticed before but the disconnection time for final circuits greater than 32A is 5 secs on a TN earthing arrangement. Does that mean a shower has a disconnection time of 5 secs? Although this circuit would also fall under protection of an RCD?? Also, cooker circuits...

    Hi, Doing wiring for a kitchen co. Done plenty of these recently, but we've been doing all wiring from scratch and have just run 16a radials direct from board. In this instance it's a ballache to run back to board, and I've got a perfectly decent 6mm cable from board to oven location. I'm...

    32A commando socket without isolator

    Any issues with installing one of these without an isolator? The D.B is about 3 meters away and the commando socket will be mounted under a kitchen worktop for a coffee machine and there isn't enough room for an isolator.

    Mobile equipment not exceeding a rating of 32a for use outdoors.

    Could someone please give me examples of what this would cover. I'm assuming it's irrelevant to portable equipment like a lawn mower on a domestic installation and more to do with industrial. Thanks in advance.

    2.5mm on 32A MCB

    Just wondering what folks would do if you came across this on your travels. 4mm radial sockets circuit, on 32A MCB. Two branches from the CU, one supplying 6 double sockets, wired entirely in 4mm, so fine. The other branch consists of a 1m run of 4mm to a double socket, then around 5m in 2.5mm...

    4mm 32a Radial In Trunking

    Changed a CU today and noticed the kitchen sockets were wired in 4mm t&e surface mounted in trunking and on a 32A breaker. Now, the CCC for this is strictly only 30A (ref.method B). Would anyone be overly bothered about this? Common sense tells me that it is unlikely this cable will be asked to...

    Why is a cooker circuit generally 6mm and 32a

    As above why is this as I have had a thought and a 20a 2.5 mm cable would be sufficient? Even in my new built it has an oven and hob both 32a radials for each on 6mm cable? Each with a 13a plug on the appliance as diversity shows around 10a max. so even with an upgraded appliance I don't see...
