I think you can take it that they're the genuine item then and they're not necessarily displaying their SABS compliance on the actual product although I couldn't for the life of me begin to guess why not.

Their concerns around the lack of main circuit breaker were similar to mine although it is plausible the Eskom protection could fulfill the requirements under certain circumstances. I think the problem with relying on the Eskom MCB for DB overload protection is that there's nothing to stop it being replaced or even being removed by Eskom at any given time if there was alterations to their network for example.
