I've got 10 MCB's in the house unit, selection of Schneider, Square D and Chang, with a 2P 63A Schneider main breaker.
Would like to replace the main breaker with a 2P 63A RCBO unit.
Chang and Schneider appear to be interchangeable. Chang is available locally, Schneider is a bit of a drive.
Not sure if I want to order online.
No desire to switch out the 10 MCB's. Can live with one RCBO to rule them all.
Any reasons NOT to go with the Chang instead of Schneider?
