Hager RCBO / MCB / AFDD devices are retrofittable in 18th edition (metal) Hager Consumer Units only:
Guidance Notes for All Switch Disconnector Consumer Units
Switch Disconnector Incomer Surface Mounted Consumer Units
- All current SD metal Consumer Unit designs are verified with RCBO / AFDD
- Ina & Inc ratings for these Consumer Unit designs are maintained when RCBO / AFDD devices are employed
Switch Disconnector Incomer Flush Mounted Consumer Units
- For retrofit applications the Internal neutral cable is required to be uprated to 25mm to retain board Ina rating ( cable part number – KE03B )
Guidance Notes for All 100A Dual RCCB Consumer Units
100A Dual RCCB Surface & Flush Mounted Consumer Units
- All current Split load dual RCCB metal Consumer unit designs are verified with MCB/AFDD
- When used in conjunction with outgoing MCB / AFDD devices, the Consumer Unit assembly maintains an Ina of 100A, however the Inc rating of each RCCB where MCB/AFDD are fitted will need to be derated to 80A. To ensure this the upstream overload protection for the board must be provided at a maximum of 80 A or, the sum of the downstream devices for each RCCB where MCB/AFDD are fitted to be equal to or less than 80 A
