Most of the information posted on the internet relates to electrical systems which conformed to the 16th or earlier editions of the IEE regulations, and given the fact that electrical theory has not changed since Maxwell's equations, and little has changed in the way of available technology...

Many thanks for your comments. As you can perhaps gather I'm generally au fait with the principles of domestic wiring (and very good at searching the internet) which means that I want to have a meaningful discussion with any electrician I commission to do work for me. I'm not prepared to just...

I accept that a RCD in the consumer unit is potentially safer for external sockets, and for bathrooms, but, as I understand things, on a split load consumer unit many of the circuits are not protected by the RCD, so that in effect one is merely replacing a fuse by a MCB. How is that safer?

I am considering having the existing fuse box (which has the old wire type fuses) replaced by a consumer unit with an RCD. However, I note that the existing system has PME type earthing and it's therefore not clear to me the installing a RCD consumer unit will add much by way of safety...

The manufacturer says that I should fit a double pole isolator spur before the pullcord switch/light switch. This will be very difficult because of access. Can I instead insert a three pole isolator immediately before the transformer? Also, could I incorporate two RCD devices in the...
