[QUOTE="phil d, post: 439400, member: 27126"] I think mixing breaker makes, assuming they will fit properly is down to common sense and judgement, suppose you had a large 3 phase board in a factory, and they needed a new 6A circuit for a couple of outside lights. Now if you were unable to obtain that make of breaker because say it was an obsolete board then you are left with only 2 options, either fit a breaker of a different make, that fits securely and is suitable for the application, kA rating etc. Or option 2,which involves replacing the whole board, this is going to be, more expensive, and will either involve a shutdown of some sort or mean waiting until the normal shutdown occurs. Given the increased costs these days how many factory owners are going to be happy when a job costing say 2 or 3 hundred quid suddenly escalates to over a thousand. [/QUOTE]
