Old MK Sentry and RCBOs ?

[Moley]

In our workshop/stores unit we've got an old MK Sentry CU with no RCD. The work benches all have RCD sockets. I'm planning on putting in a new radial for the washing machine and wondered if a current RCBO would fit in the old CU or if a RCD socket would be the only way forward.

It's a nice size unit. Can get 4 Transits in with ease and only 2 of us that ever use the unit, and I'm mainly there to work on my own stuff Now that I've fixed our donated washing machine (pump bearings worn) it should stop my own washing machine from smelling of transformer oil.

Could you install a fused connection unit instead of a socket?
Rcd might not be required.

If it is definitely needed, I might have one kicking about, just let me know and I will search for it.
And No, the new ones don’t fit the old boards.

If the RCBOs won't fit and I would like the washing machine on a RCD I might just fit a fcu to the ring and a RCD socket. It'll save me running a fairly long radial and conduit around the workshop.
