OK. I read that as a reference to a component rated at 230 Volts running at 248 Volts,
and a question being asked if the resultant output voltage was a problem.
I’d say it’s a fair bet the European system voltage wasn’t what he was speaking / thinking of.
Many in the US have little or no idea what the voltage standards are in other parts of the world.
They can’t get it straight at home, let alone another part of the world.
Lots of them refer to our 120 / 240 Volt system by the long-outdated term 110 / 220 Volt.
Of course, that’s no excuse for not looking up said information.
I couldn’t help thinking that there might be some confusion, hence my question.
