Hi There!
Background info:
Domestic/agricultural premises.
TT 3 phase supply and main distribution board located inside stables (agricultural location).
Several solar systems, storage battery system + EV charger connected - (lots of DC current's being introduced)
Single phase submain from main distribution board supplying domestic flat (inc. car port with EV charger + rooftop solar installation) does not have RCD protection.
3 Phase 25A solar circuit from main dist board also does not have RCD protection.
Type B RCBO would be perfect but is unavailable.
Looked to see if I could find a Type B RCCB incommer for the Schneider distribution board but unavailable.
2 options:
1) Add RCD protection to Solar and Single phase submain separatly.
2) Fit an upfront 300mA, Type B, 100A, Time delayed RCCB
I figured option 2 would be simplest but the device I found was £1500 DFS 4 100-4/0.30-B NK
It's looking like the independent protection will be cheaper but before I look into that can anyone offer a different angle to approach this, or alternative device that's more affordable?
Thanks
Chris
