Old type Pproteus CU RCBO retreofit

[empress]

been to have a look at a job today ,its got an old horrid looking Proteus CU.
The old square box type with slide knockout entry plates top and bottom.
Lots of spare ways so looking for a 40amp RCBO for an inline heater that will go in any ideas.
seem to recall MK mcbs went into these but rcbo with extra height are a different puppy.

Might be pushing it to fit rcbo, I seem to remember legrand fitted these boards aswell.

If the board is young enough to have 60898 breakers in it the Wylex RCBOs fit. Had one of them in a large Proteus consumer unit recently but this one was a 3 phase unit converted to single phase.
