LOL, VERY funny  :-DD  How about - test the control rod mechanism in a nuclear power plant?

Mine is still in transit - I ordered an AN8008 from Amazon on July 16th thinking that it was shipping from the USA.  It says "Package received by carrier CHINA" as of July 19th and is supposed to arrive with me in the US between 4-25 August!  I paid a couple of dollars extra at Amazon but they don't specifically make it clear when something is coming from China which eBay does  >:(  but my experience is that stuff often arrives much sooner than estimated when coming from China.

ANENG AN8008 is re-branded model of the Shenzhen ZOTEK Instruments ZT-109

The funny thing is that the ZT-109 is a lot more expensive than the AN8008  :-//

Are they totally identical inside? I wonder if the TX pin is bonded in the more expensive Zotek version.

Too much exotic thing.
My imagination on these categories ends on the simple substation stuff. Large busbars, high current, etc.

I agree that the risk of disrupting a conductor sounds strange for a high-energy circuit. There are some adapters that allow interruption of mains conductors without exposed wiring. In addition, some AC current clamps have an output of 1 mA/A, so they require a mA jack to use.

There is also the current that flows if you accidentally leave it set to current and connect it across a voltage source (or even set it to voltage with the leads in the current jacks for meters that do not have a jack alert)? Humans make mistakes, and a good safety systems are there to prevent people from getting injured/killed by those mistakes.

If you want to prevent those mistakes, then you can use meters without current jacks like the Fluke 101 or Fluke T5-600/1000. No expensive fuses to blow either ;).

Didn't know that. Thanks for clarification.

Thanks, but I never had a problem with the choice of dmm.

Also those type of adapters is great. I use this: http://www.pinsonne-elektronik.de/media/images/ut71_poweradapter.jpg with the ut71e for a couple of years.
