two radials on 16 a mcb

[telectrix]

Trying to get this thread back on topic:- You can not have have 2 circuits from the same OCPD. You can have one radial socket circuit with a spur from the MCB if feeding only one point!

Discuss?

no, you can have unlimited branches. it's only that you can have 1 unfused outlet from a RFC, tapped off at theOCPD.

Branching off a radial is fine from a socket. Branching from a MCB?...... I was thinking along the lines of separation of circuits but at the end of the day, if it was a RFC in the first place it would serve the same floor/area so no difference really.

welcome to my world.

But remove the RFC leaving the 2.5mm radial with one double outlet on the 32A MCB and it suddenly becomes dangerous and against the regs, much in the same way that an insulated consumer unit will inevitably catch on fire now it's not to regulations.

Just measure Zs at each socket on the circuits, and record the highest value for each circuit.
I wouldn't bother with measuring R1 or R2.
