Yes. We spoke to the electrician today and we think we know what the problem was. Even if we have measured the power/amperes on all channels and it's fine, we get some power peaks when some LED power supplies are connected at the same time. And then the fuse goes out.Everything ok, now?
But Lasse figured it out and now everything is working fine again.
Next step is when they start building and cut the power to the whole museum and we will have to use power from outside.. Might be in two weeks, or two months. More adventures..
Yes, and I will do an extra overflow to the drain from the sump(so we won't get water on the floor when the return pump goes off). Haven't had the time yet..
