Fuse size

[Jimmyb]

Just wondering after doing a job today, what is samllest fuse size you would use for sockets in a kitchen if there wasnt a washer or dryer in there ?
I put a 32a mcb with 4 double sockets and a single and when all finshed i did think with the loads present surely a 25 or 20 mcb be ok. I always had drilled into me 32 for kitchen no less for years even if there is no big app.

why not just break the ring and turn it into 2 radials?, if you have a ring on l + n but 2 radials on cpc, where are you getting your R1+R2 from?

ahhh right, get ya, the conection of line and neutral and face plate says it all, so 2x Zs tests on this ring final cheers

OK I’ll echo E54, the MCB is to protect the circuit.

NOT the load, the plug top or FSU fuse take that responsibility.

Because I knew where the break was, I knew it wasn't a hazard as it wasn't current carrying and it was safer and easier to leave it intact

R1&R2 measured and recorded as per radial, offending socket removed and blanked so all remaining had continuity
