I didn't say brand, I said manufacturer! for example BILL brand stuff has been the same kit as MEM for years, different brands same manufacturer. Wylex, crabtree, volex are all electrium, different brands same manufacturer.
Clipsal who are being discussed here is schneider.
Cheap chinese tat just shouldn't be used full stop as a matter of common sense.
The issue with mixing kit from different manufacturers broadly comes down to requiring the manufacturers permission to fit kit made by someone else into their boards, they have tested and approved their kit in accordance with various standards but not other peoples kit mixed with theirs.
If you put someone else's circuit breaker into your board you in theory have to then test and certify it as a product in the same way as panel builders have to certify their panels made up from various bits of kit.
(That's my understanding of it anyway + a bottle of wine)
