Indeed. Which is why the DP devices are not used that often. The 17th
edition rules for cable protection made RCBOs more desirable (or at least
multiple RCDs[1]). The manufacturers have responded to that need and also
the one of conserving CU space by introducing far more competitively
priced single width SP RCBOs. These are still not exactly cheap, but at
under £20 in many cases are affordable. (still MCB prices are under £2 in
some cases now,

S/fix sells the cheapest RCBO at around £28. Les than £20? Where?



At an electrical wholesalers. I pay a lot less than £28 for RCBOs
