Will new MK Honeywell RCBOs fit onto the din rail of a MK consumer unit.
See attached pics of the existing consumer unit.
I have been asked to replace this consumer unit with a new dual RCD unit as the existing unit has no RCDs fitted. However because it looks like the consumer unit was installed and then the cupboard fitted around it, it would be very difficult to replace. The other option would be to keep the consumer unit but replace the MCBs with RCBOs. A wholesaler has quoted around £30 per MK RCBO but I have seen online RCBOs by Honywell MK
( Honeywell are the owners of MK) for around £13. Does anyone know if these new RCBOs will fit on the din rail of the existing consumer unit? Thanks for watching.

Sockets will probably be ok on one, a little inconvenient in the event of a fault though, I'd probably like a 7th rcbo in. Wonder if hes linked...
