Actually Edison Illuminating Company of America installed the first electric lights on the UK railway in the 1920s at Fenchurch Street (London) so they used what they were experienced with ... and because its safer.

Receiving a shock from 110V is unpleasant, but it is less likely to lead to significant harm than a 240 V shock.

Re: [PSES] Interview Questions
I think Ken is on the right track. Railroad signally and portable equipment both represent areas where there is a higher risk of exposed connections. Receiving a shock from 110V is unpleasant, but it is less likely to lead to significant harm than a 240 V shock. I've contacted 110V a number of times and it seems to have had no ill effects other than starting e-mail messages with bad puns.

[PSES] Interview Questions
Hello All, I have recently been tasked with writing a set of questions that job candidates would need to answer at the same time they apply for a position requiring knowledge of product safety evaluation, testing and practices. 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.

Re: [PSES] Interview Questions
Well don't try - what is the sound of one hand clapping I asked Siri (iPhone assistant thingy) and she gave me an answer. (Silence) Try to avoid definitions and work the question so they have to demonstrate knowledge of what things do. You might try, if you have inadequate creepage distances what alternatives might be available? (through insulation is what I had in mind) They can look up creepage distance all night long but unless they known a little something about what is being accomplished with creepage distance they can't come up with an alternative.

Re: [PSES] Interview Questions
Not sure this is what you are looking for; but the 110-230V unit is rated as a range, so the tolerance would be below 110 and above 230. 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.

Re: [PSES] Interview Questions
Pre-screens that attempt to minimize consumption of a candidates' time is a
good thing.
What if the candidate logs in to answer one or two questions that evaluate
engineering judgment and/or problem solving? Perhaps you have to consider
that the knowledge of... stuff cannot be used as a first-pass screen.
This is best evaluated in-person.
I have had several interviews that focused on knowledge (facts) questions -
useless if it is something that can be looked up by a 2-second computer
search of the a standard or on-line data. The more obscure the knowledge
element, the more likely that it can be rapidly found with access to the
correct documents. With exception of one company, I am glad that they
('fact-based' interviewing companies) passed me up or I passed the company
up. A fact-based interview is shallow. Problem-solving interviews indicate
depth of thought by both the interviewer and the interviewee. Realize that
the superior candidates will also evaluate the interviewers.
The best compliance-related questions that have been posited to me follow:
1. After a few minutes discussing the circuit in a schematic - 'What is the
method that this converter uses to detect overload, how would Type-Test it,
and why?'
2. Is this code safety-critical? Why or why not?
3. Provided simple fly-back converter schematic and PCB layout and WV table
and calipers - 'Evaluate the spacings and provide general component
requirements for the circuit node outlined on the schematic'.
4. 'Do you prefer Agilent or R/S? Why?'

Subject: Interview Questions
Hello All,
I have recently been tasked with writing a set of questions that job
candidates would need to answer at the same time they apply for a
position requiring knowledge of product safety evaluation, testing
and practices. 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.

Re: [PSES] Interview Questions
I believe Nick may be fishing for the answer - a voltage selector switch. Back to the original question... Of course, an interview is much better for assessing this type of knowledge, but if you have to have questions on an application where candidates fill it out from home, you could ask questions based on personal experience, such as describe an experience you have had where you solved an issue with creepage distance and how you did it or something like that. People could always just lie and make something up, but it should be pretty easy to tell if someone has no idea what they're talking about. Much harder to Google this type of specific problem and solution, I would think.

Back to the original question... Of course, an interview is much better for assessing this type of knowledge, but if you have to have questions on an application where candidates fill it out from home, you could ask questions based on personal experience, such as describe an experience you have had where you solved an issue with creepage distance and how you did it or something like that.

Reminds me of back around 1994, when I interviewed at a now World-famous company for a position as an EMC engineer. I spent a very long day talking with 5 engineering groups, each of which had classic problems (shielding effectiveness, internal coupling, export compliance, CE RE). While I can't say I fixed every problem, I was able to set each group on a righteous path to their goal. And a few days later, their HR droid told me that, on reflection, they now thought they didn't really need a full-time in-house EMC guy. So that's how they were so profitable! The best compliance-related questions that have been posited to me follow: 4. 'Do you prefer Agilent or R/S? Why?' Hey, don't diss the Anritsu Thurlby guys!
