Hi johnsandywhite,
Thanks for reply, I have tried the method you suggest but it is still in the lap of the gods whether it takes or not. It is however comforting to know that the problem, if that is what it is, is not confined to me.
Apparently the problem, according to the manufacturer, is caused by the start up inrush current which can be surprisingly high, to quote them:
"We have calculated theoretical in rush currents and they are as follows:
750va 49amps
1000va 76amps
1500va 140amps
2000va 185amps
3000va 337amps
Please note these are absolute instantaneous maximum currents which assume the switch on point is at the crest of the AC wave form. In more realistic terms, I suggest you assume quarter of the values given above"

There appear to be other factors which can exacerbate the situation, one being that site contact breakers, or home come to that if you are hooking up there for maintainance, should be type C, and not the normal domestic type B.
I also spent some time searching, unsuccessfully, for a Soft Start switch.
As stated earlier, it looks as if the Reich Fuse Control will be as good as it gets, for me at least.

Hi eupho. Although nowadays I am not a regular Site user. I find the best way is to couple everything in with the onsite switch off. Then click the trip switch on. Then if it trips you are there to switch it back on again. Wink

Hi johnsandywhite,
thanks, next time as long as the breakers are accessible, I will try your method although with my fuse control set I am not anticipating, fingers crossed, further inconvenience.
