Detect presence of 230v - not measure

polymorph:
I said if you -connect- at the zero crossing. I apologize for not being more clear, I did not mean that the max current happens at that time.

I think I understand what you meant now, but I still disagree. The initial peak occurs at about 0.9ms, and is actually slightly less than the maximums reached on each subsequent cycle. If I'm still not understanding then I may need a picture :wink:
