Nobody will ever let you know
when you ask the reasons why
they'l just tell you that your on your own
fill your head all full of lies!
sorry, just thought it was a bit apt. Mixed MCB's Skelton bang on as usual, what a load of will young.
Unfortunately in this case Mr Skelton, is well off kilter, and totally incorrect.
He actually knows this in his heart, I'm sure, if he has done the research that he asked me to help him with several months ago, hence the tone of my comments.
If he has not done his research, then I urge him to, and the peripheral related topics that will unfortunately bring him to the same conclusion that I have had to come to, like it or not, after doing my research, I tried to argue the point with Schneider, and lost, because they pointed out a few points in the standards that I had missed.
Like it or not, & TBH I don't but, you can't do it without the appropriate testing, see BS6432 if you want to know what is required, that covers the requirements for mixing and matching MCB's, so like your scams require you to have 7671, if you are going to modify switchgear then you need 6423.
£168 from BSI, and you lot think 7671 is expensive.
