The final English exams of my fourth graders had a nice surprise. And I can guarantee you that they know what a catfish is :D :D

I have nightmares about something like that happening.. Hopefully those residual current circuit breaker things would catch it..

P.S. I think the answer to Q39 is A. I (think I) understand what it means, just don't ask me to pronounce it :lol:

They should but you can check it without zapping yourself. Just plug in something with a heavy start or heavy load like a vacuum or an iron on high. The very sensitive ones pop when there's any change in the current.
Mine popped off when I almost plugged a small light in and had the slots backwards. Very sensitive, I wasn't even close to having it in the holes all the way.

This is from the book so no electricians here will have to clean up the above language :oops:
A GFCI monitors the amount of current flowing from hot to neutral. If there is any imbalance, it trips the circuit. It is able to sense a mismatch as small as 4 or 5 milliamps, and it can react as quickly as one-thirtieth of a second.

After reading that, the kids must think you're very brave to have such rowdy fish! :lol:

Actually, some thought I was responsible for the question. But this is a so called Central Exam (nation wide, so every fourth grader of this school type in the Netherlands has to do it) and I had nothing to do with it - alas :wink:
