Japan, and some Carribean stuff - does knowledge of this fact make me a better compliance person? No.
And a voltage switch is NOT necessarily required. Think auto-switch power supplies.

The 110/230 V has two distinct rating ranges, so the tolerances would be above and below 110 AND above and below 230VAC. That's the first thing that pops into mind, anyway.

Here is one, adapted from a phone enquiry I dealt with this morning this morning: You have two appliances. One is marked "110 - 230V ~50Hz" and the other is marked "110/230V ~50Hz". What do you look for on one which is missing from the other? I'll let the group answer. Nick.

These questions would serve as an automated pre screening mechanism. Questions like "What does the term creepage distance mean?" would be perfect , however the challenge that I am facing is finding questions that the answers are not easily found using Google. If anyone has any product safety related questions that they would not mind sharing, I would greatly appreciate it.
