I like some off-topic stuff, including cartoons...but maybe the "Off Topic" thread is a better venue for them?
On a different theme, man said today, as I asked him some questions about rewiring this building...
RFC or radial?
Go with RFC
OK, cooker circuit? separate circuit?
Yes, every day.
Fair enough...
I'm thinking 10mm, but with diversity could be 6mm, however, cost isn't an issue so I'll go with the 10mm.
What's diversity?
2.5.mm rfc x 3 for sockets?
Yeah, whatever...
Clipped direct? We are plasterboarding 12mm but there will be 300mm insulation, so keep it clipped direct to joists?
Oh, it won't matter, we're throwing in a load of rcbos so they'll take care of any problems, just carry on.
1mm or 1.5mm for lighting?
Oh, whatever you've got handy will be fine!
Now, you all know I am not an electrician, but I am happy to lay in the cables and sockets and light fittings etc.
however, and I may have this totally wrong, but wouldn't you calculate the cabling and loads, then specify the protective devices, rather than think "Hmm...RCBOs? They'll cover everything!"
OK, they have to be sized accordingly, but I kinda thought the circuit design was the most important element. I mean, we won't go far wrong with 2.5 for sockets and 1 for lights (they will all be LED) and 10mm for the cooker (2 ovens and 5 rings...don't know the rating yet) but it's a 10m by 10m building, single storey so no fancy stuff...
Apparently, this kind guy is going to inspect, terminate the circuits and issue certificates, so why should I worry? It's a charity, and we are very lucky to get his input. Just concerned...
probably shouldn't be...I'll lay the cables, do the sockets. let him test...
or should I be concerned?
