radial circuits can't be overloaded, because the cable carrying capacity exceeds or equals to the mcb rating. On ring circuits, spurs are not required to be spurred with a 13a fcu, so it's possible to plug a dishwasher and a tumble dryer into the same double socket, drawing 26 amps on a 2.5mm...

Sorry, but I fail to see the problem - you label the socket as being for lights only, the circuit cannot be overloaded as the breaker will trip if the user tries. that's just bad practice, not right really. What I want to know, is why electricians don't use 20a dp switches on 15a or 20a...

what I mean, is that there are so many things which are actually a danger which are completely missed by inspections, neglected by building control e.t.c. yet people are paranoid about simple things which deviate from the norm, which in actual fact pose no practical danger at all. For example...

There isn't a regulation that you can't do that, there probably is guidance that you can't, but it's common sense. You shouldn't install something that could potentially draw more current than it is designed for. That's what 2a and 5a sockets were designed for. And the majority of US radials are...

The thing is, you can't install a 13a socket on a 6 or 10a mcb, you may be able to use 1.5mm cable if the distance is suitable, but 2.5mm is more often than not required for power circuits. I know the old type of plugs you've mentioned with the 2x2a and 1x13a, but problem is, it's very...

you're a very heated poster aren't you ban-all-sheds? where you're wrong, is that buildings regulations are the law, you are legally obliged to apply for building consent before carrying out any works, and you're legally obliged to have it tested. If the person testing deems anything...

Ban-all-sheds, just as building regulations are strictly guidelines (not a legal requirement as people assume, unless in a commercial situation where public safety is concerned), an internet forum is also designed for people to share their experiences and opinions so that other people can make...

Hi, I've recently renovated an apartment, and due to the style of the building, I opted to do away with the ceiling roses in the huge bedroom (it's a 1930's building and the original conduit wiring was disconnected years ago, and new wiring installed cheaply in plastic conduit on the surface of...

Hi, a while ago we did some landscaping in the garden and laid a single length of 6mm 3 core SWA cable underground in pea gravel from the house CU to an outhouse in the center of the garden (20 metres). Then 4mm 3 core swa another 20 metres from there to the end of the garden (40m total from...
