The IET have released some 'errata sheets' to correct some errors in the Onsite Guide and Guidance Note 3!
IET Wiring Regulations updates - IET Electrical
Planning a re-wire of a very old thatched property.
All lighting will be via 2A sockets (except bathrooms) and some of the walls are just wooden planks (building control are very protective about them) and it wouldn't look nice clipping cables on the surface to a switch on a surface pattress...
My point was more to the fact that the regs trys to protect anyone that doesn't have a tool (eg. screwdriver). Anyone with a toolbox can do anything they want, not just change 13A plugs to 2/5A plugs. It just can't legislate for the morons with a screwdriver! In which case they deserve all...
I see your point but its all open to interpretation!
Note b of the reg you have quoted (411.3.3) states that the socket does not have to be RCD protected if its 'provided for connection of a particular item of equipment' - which the 2A/5A plug does, to my mind.
Obviously some muppet could...
The reason the RCD is tripping is you've probably got a N-E fault on the lighting circuit.
When you have a high current appliance on (oven/kettle) then the resistance of the fault is small enough to divert a small amount of current through the N-E fault!
I specifically asked the owner to ask them. Got a copy of their email as well (NFU).
Just mentions:
No recessed lights in ceiling unless fitted with fire rated hood (minimum 1 hour)
Minimise wiring in loft
External lights should be >1m from thatch
