Steeple RCBO

BathSparks · Nov 25, 2013

I wanted to add a couple of sockets by the windows of a small clothes shop. The easiest way, I thought, was to create a new, radial circuit. The C.U. is a Steeple and there are two spare ways into the board.
The existing circuits are protected by RCBOs so I bought a new one from Denmans.
When I came to install it there was a problem. The 'heal' of the RCBO is too long and prohibits its use as this interferes with the other circuits. New and old RCBOs are referred to as 'DSBRCBO20B' for a 20 Amp and are EN61009-1.
I have looked on Ebay and can see 32A and 6A versions of the RCBO I am looking for.
16A and 20A versions only show the box they come in?! So they may be the wrong type

Type E are older than these I believe.
When putting the bus-bar, the RCBO in slot one turns for ever and looks like a stripped thread (have ordered one of these from Ebay).
All in all, what started as a simple job as turned into a bit of a nightmare.

Lessen learned I hope Bud. In future order the correct breaker. Denmans is the place to go for a Steeple.

The lesson I have learned is - run a mile if I see one of these again. Denmans do not sell the right parts for this anymore.

Agree with point one for sure

Had a similar problem with steeple, very frustrating when they change the size of mcbs and don't have anything to fit in existing boards that aren't that old.

Yer, I believe it is called 'planned obsolescence' by some pinstripe suited accountant, it sucks.

Looking at that photo, it's the original RCBO'S that are wrong going by the gap between busbar and breakers, that or the main switch is wrong!! lol!!

aBO is spot on with the main switch and the original RCBos are the wrong ones. and that copper showing on the right end of the busbar, now that's a shocker!. LOL.
