Things have apparently changed since I last picked up the book.
You don’t need RCD on lights if you can see the wiring.
look in the stickies...
Bernard, if he splits the difference and puts the double where the 2 “middle” outlets are out of the 4 ( with a new deep back box with extension...
I'm sure you can get ones with an led strip all the way round..
there are minimum clearances and so on..
plasterboard lining with fire hoods and a fan for ventilation?
To clarify.. the switched live at the fan should be the one that's on when the light is on, the other one is the one mentioned above..
It's the switch end..
take the one which is suppose to be permanently live and connect it to the one in the switch that is permanently live.. (...
Provided ther are the same size yes..
Wouldn't a double pole switch get rid of this?
Break the neutral and no current flow.
But that involves re-wiring probably.
It's been a while since I've peeked at the regs but I thought that fire rated were only needed in a ceiling used as a fire barrier such as a...
Several alarm bells rang on reading that first post..
1:- "?.. issue with THE socket circuit..." .. there should be at least 2.. upstairs and...
Ah.. I've found the PDF..
turn the switch off..
The humidity is automatic with the switch OFF
Turning ON the switch turns on the fan which runs...
Is there a setup time for the humidity stat? What do the instructions say?
The old extractor had a permanent AND switched live but no timers etc?
The browns in the crimp should be the permanent live,...
Could be the beam angle?
Are the replacement ones reflector type?
4 way wago connectors? ( 1 in, 3 out )
Safety's by means of placing out of reach.. ?
Irrelavent as to what "the norm" is in your opinion.. the OP asked about de-rating, not "rule of thumb" circuit design.
If you need to use 1.5mm...
Yes and no..
you have a design current ( e.g. A 20A radial ) and you know that the route / method means you have to de-rate any cable by 50% so...
Generally it's done at install..
any de-rating is taken into account and the cable and / or breaker sized accordingly.
So you get 1.5mm cables...
If a cable cannot get rid of the heat generated by the current running through it then you have to lower its maximum rating.
If it's in...
