翻译 - 丹麦语-英语 - Det kan være farligt at arbejde med højspænding.

Hi Pia, this would sound better in English with an inverted structure:
"Working with high voltage can be dangerous."

What do you think?

Ok

Btw, why is it wrong to translate it as I did

It can be dangerous to work with high voltage.

Did I say it was wrong?
I said it would sound better, a more natural way to say that in English.

No, you didn't! But since you don't accepted it as it was, I thought so. I guess (?) a sentence like this can be said in different ways (word order), but still mean the same and be correct...I thought that maybe was the case here.

And it IS the case here.

Besides your sentence and mine, we could make some other sentences with different wording and still meaning the same thing.
What about:

"High voltage can be dangerous to work with"

And...I didn't say I wouldn't accept your version. If so, I would have posted:
It can be dangerous to work with high voltage. ---> Working with high voltage can be dangerous.

Wow ..I'm getting on your nerves Lilian!!

I understand your way of work, and it's true, you did asked me if I agreed.
