Hi,
The builders are extending the kitchen in my house at the moment which means putting in an extra 2 double sockets. I'm doing the electrics myself. I plan to to fix an unswitched 13A FCU to the spur off the ring main and put the 2 new double sockets on it.
I have been looking at the big red book; Appendix 15, the one with the ring diagram. I'm confused on the cable sizing. The diagram in the red book coming off the main ring is an FCU with a cable size of 2.5mm but coming off the FCU to a spurred socket is a 1.5mm cable, fair enough.
In another book, (Electrical Installations 2330 Level 2) it confirms the above but it says a MINIMUM size of the conductor is 1.5mm for a fused spur (I assume you can't go lower than 1.5mm but can go higher??).
Taking 'MINIMUM' into account does that mean I can use a 2.5mm cable instead of 1.5mm cable between the FCU and the new socket? Bearing in mind I need to run a washing machine and tumble drier and possibly a fridge off it...
I'm new in the world of electrics, passsed my C&G 2330 Level 2 and other bits not long ago and trying to gain experience and break into the field.
Another certified and registered sparky is going to come and inspect and sign off my work once its done - I'm just saving face asking him a question that may seem silly...
Any advice would be appreciated.
