Hi

I have noticed that unswitched 6 amp sockets have been extensively used to connect fixed roof fans in a building and fixed extractor fans in bathrooms .
I don't see where the regulations permit the use of 6 amp sockets for these applications . The only place where I can find that 6 amp sockets are allowed are in lighting circuits as per the regulations.

Is the connection of fixed appliances via 6 amp sockets not from older regulations
Does one replace all the fixed appliance 6 amp sockets with 16 amp sockets or isolators.
