Old CU replaced with new 17th edition

[P&Q]

Hello everybody,

I have a few questions, which I would appreciate any answers to.

Firstly, for a radial circuit, single socket, with 2.5mm cables T&E about 2 metres long, just for general domestic use in a hallway, what rating of type B circuit protective device would you recommend?

Secondly, for a door bell transformer, would you recommend that I put it on an existing circuit such as the lighting circuit? or put it on an individual circuit?

Thanks in advance guys

Secondly, for a door bell transformer, would you recommend that I put it on an existing circuit such as the lighting circuit? or put it on an individual circuit? Put it on with the downstairs lights not really worth a circuit all to itself.


Thanks in advance guys

20a for the radial circuit, gives scope to extend if needed.
If it's a new CU might as well put the doorbell on it's own circuit.
