Hi Clive S,

yes that is exactly the point.
Normally the current will not go past that, my 1mm2 will only carry power to 1 driver.


Until something goes wrong that is.

When a short happens on a transformer it is capable of more current.
It might smoke my 1mm2 panel wiring i believe.
But maybe the rectifier will blow out first.

In my line of work the secundary fuses also match the spec of the panel wiring.

So i think a secundary fuse might be a good idea.


While is was looking up data on my particular transformer, the datasheet mentions the precense a TCO in the primary windings... so transformer thermal overload is sorted.



Can't find any specific data on max fault current though..
Maybe it can be calculated ... not my field of expertise.

Grtz Bert.
