Addition DSOs on a radial - good practice?

[HandySparks]

.... It's going to be notifiable work anyway...

Why?..

As suggested, please see attached pictures (if this works...)

I didn't think i needed to notify the LABC because I'm only adding DSOs to an existing radial circuit. I see this as almost the equivalent as plugging in a 4-gang socket extension lead.

hopefully the photos will make it clear what I'm trying to do...

Ah. I wouldn't describe the SWA as "three core and earth" it's four core (one of which is used as an earth).

"Twin and earth" or "3 core and earth" is described as such because the earth conductor is a reduced size compared to the other cores, and un-insulated, and therefore unsuitable for any other function.
