I think i would like to go down the rcd or rcbo route tbh... Even just extend the ring with an rcbo...

P P Yes thats what i meant earlier, two radials is another option.. Please reply so i can pot a link, need 10 posts haha :)

That will be my option sidewinder i was just curious if the load would be greater than 13amp on radial and the ring had to be extended, what the options would be.. Thanks.

If any new work has to be to 17th like just stated by special location then once a ring is extended how can you ensure the sockets have rcd protection without an rcbo? I meant verify earth and bond and capacity, special locations no2 Thanks

Great example and advice :) thankyou Now i undertsnad that only NEW work has to be to new regulations and new work doesnt effect the origin of the circuit. Right? "Unless you can point to the reg that states all wiring and cu must be upgraded after every installation" was also what i wanted...

So an addition to a ring main with an rcd spur running numerous socket outlets would satisfy the regs? Also back to my original question, if in a situation where a ring had to be extended, an rcbo would be acceptable? Instead of an rcd CU? Thanks sidewinder appreciated. Thanks bet.

This is were i don't understand because even then you are still modifying an existing ring main? Yes i understand what you are saying but things are different to what i do everyday, hence why i went on the 17th to try and educate a little more with whats out there... I want to do the job...

Out of interest then, a cu without rcd protection, any circuit modified that now requires rcd protection, does rcd protection just have to be fitted on the circuit worked on? Here stories about electricians not touching circuits unless the cu is replaced to one with and rcd, this is whats...

So all other existing circuits will be fine if untouched when inspection and testing is taken out?

Hi all, new to the forum and looking for a little advice. I am wanting to know what the situation is when adding to an existing circuit (ring main) and (lighting circuit) when the CU has no RCD protection. I am aware all socket outlets up to 20A have to be covered by RCD protection unless...
