[QUOTE="300TDI, post: 57294"] Now this is where it gets mixed up Square D made a board called QO range, this has a circular clip which clips onto a rail.They made this board obselete and replaced it with KQ which has the push in prongs. Then they made a consumer unit range called QO which also uses the KQ style push in prong system but the mbcs were b type Then they made consumer units in the Domae range, these are the same mcbs as the prong type, but you need to remove the prongs first Nothing is interchangeable from the old QO type, but the current ones can be mixed, taking into account the prong system [/QUOTE]
