This was raised on another forum. I took apart my cheap Cactus trigger receiver, found the data sheet for the opto-triac used to trigger the flash and found that it was rated at 400 volts. I suspect most modern cameras use a similar device but conservatively rate them at 250 volts (which seems to be the standard now).
