Nearly fifteen years ago I moved a bathroom in our house, and repurposed the 32A electrical shower circuit to power a pair of double sockets - which then had multiway adaptors powering all my office hardware (i.e. low overall power).
Not exactly complex or risky at the time, and the MCB has always been RCD protected.
However, I am now in the midst of a loft conversion, the ex bathroom, ex office is now just part of the landing with the bottom of the new flight of stairs.
But I need to provide sockets in the new bedroom upstairs (so a hairdryer is likely).
Taking another look at the wiring for these sockets it is a simple radial circuit from the consumer unit - 32A MCB, chunky red/black cable into the first double socket, and then spurred to the other (still in red/black). (I've not measured those cables yet, but they look rather chunkier than ring main cables).
To save chasing down to the consumer unit (which is in the entrance hall directly underneath the bathroom/office/landing) I have a few choices that would all work from a power delivery perspective:
- Run a ring from this point
i.e. leave the single cable to the first floor, but ring from there up and round.
- Run a ring from ceiling level
i.e. run a single cable up to the loft floor level and a ring from there.
- Run the whole circuit as a radial circuit
i.e. just don't bother going to a ring at all.
I'd also like to retain one socket on the landing for a night light and the hoover, but a spur at that point is pretty trivial.
Obviously this lot will need to get passed by building control, so I will be asking them, but I'd like to go into that conversation with a bit of other people's experience at hand as well.
Cheers.
