Pauluk,
Just reading through your side of the site and came accross the problems one of the members was having with RCBO`s, having been in the electrical trade for about two decades now and having used the various suppliers with the country, the only ones i will now fit are the `field fit` RCBO add ons to the MEM series two MCB`s, these fit the standard domestic dis board as well as the commercial TP/N boards,check out your local Wholesaler ( you wont find them in the `Sheds` IE the B & Q and Homebase ) not that your local DIY er would know what to do with them, thats a different subject,
Bye for now,
John Harrison
