Xdrive: Where did you get that 350mm?
Agreed, but as the cable in a ring only has to have a CCC of 20A (albeit with the minimum csa of 2.5mm² still for BS3036 30A fuses - 2 x Iz for an...
I am getting confused.
If the switch has a current rating ≥ the cable then it will protect the switch, will it not?
Edit - I know 20A is less...
There are no regulations regarding socket and switch heights. It's your house.
Are you confusing heights of switches with so-called safe zones -...
Well, not really. Perhaps circuit rather than just cable, although that is how circuit design is done, isn't it? Load, appropriate OPD,...
I thought that was what Flameport posted.
One wouldn't have a light switch on a cooker circuit.
I would say it should - or must - just like MCBs do, otherwise the 100A switch will have to be protected by a 50A fuse. Such situations would...
I was 'assuming' or 'presuming' that all devices are rated to allow for the fusing factor of the likely protective device.
As for RCCBs, doesn't the subject raise the question of why do they bother to make ones with a rating of less than 100A.
They are, quite...
Surely if there is a 100A main switch and a 100A main fuse then that doesn't matter.
You know I'm not good at cryptic clues but what does the last sentence mean?
Which is THE OCPD? Is it suggested there should be a...
Energy Ombudsman ???
Environmental Health Department ???
Member of Parliament ???
I have just realised what you were getting at - so that is probably NOT how they operate.
Switching neutral is acceptable within a device but not...
Some say 1mm² breaks more easily but, while that is presumably the case because it is smaller, I have never found that to be a problem.
I would double over the ends of one or more conductors to fill the terminal as much as possible - whatever the size.
I suppose it is personal...
I don't think that was pedantic.
RCBOs are RCDs. :)
I had the same. Got fed up with it and divorced her.
I would imagine the 'switched' neutral switches on a solenoid/relay which moves mechanically a cog, or similar, to engage the low register digits...
Really? How do they do that?
Why do people bathe them, then?
Of course they do but that has nothing to do with being clean.
