Maybe not many replies because your post covers all bases. The missing two worms, or 20%. It is possible worms die in systems all the time but we don't notice it because we are not inspecting and as observant as you so we don't catch them in the act. I'm not sure I believe that statement. I imagine you checked and the worms were not hiding in the removed plastic cover. That leaves only two things that could of happened. Natural or otherwise die off occured to the two. Or they crawled out the air hole. Sensing more oxygen drew them to the hole and then they were free. I don't particularly like any of those three choices and still, as you do, want to know what happened to those two worms. :-) Two worms did disapear so I don't know we can say it was not the power bars. But then again no sick worms were found. If two sick worms were found, and maybe they were sick before they decomposed in to oblivian, then we might feel there was results. But would not all of the worms of gotten sick? A pile of sick worms is actually what we did want to see. Or 10 healthy worms. 8 worms is infuriating. Maybe the end result of "The Great Protein Bar Mystery" is the resulting increased interest in flow through bin design.

pjames might be on to something. I have collected manure from different piles. I always do a test of the manure before I feed it to the worms, but I only do one test, then assume the whole batch is good, even if the manure may have come from different horses.. OTOH, the die off seems to continue until long after I have fed horse manure. There is no clear consensus on whether dewormer is actually harmful to the worms. That is something I might experiment with when I have a healthy worm population. I would like to get a definitive answer on the dewormer question. I was reading an article yesterday (I can't find it now) that says that dewormer is 95% broken down in the horse's system, and degrades completely with exposure to sunlight. If the problem is dewormer, that would explain why I am only having a partial die off.

Many are either high in carbs or high in fat. You may have to check the label depending on the eating style you are maintaining. I pack Nutrigrain Yogurt Bars (three weight watchers points), a bottle of water, and the Quaker Oatmeal cinnamon sugar bars (two weight watchers points). If you have a cooler compartment to keep food cool in your bag, try the new Dannon lite and fit smoothie drinkable yogurts. They are delicious and are two weight watchers points. You are smart to think to pack ahead because they rarely have food on planes now. So if you buy in the airport it either will cost mucho $$$ or it will be unhealthy and fattening, or usually BOTH!

Thanks for the excellent responses. Currently I can answer these questions. 1) Initially the service entrance voltage was 140 - 141V. Way too high. A transformer supplying power to our unit was changed and readings are now correct. Oddly, at 141V the tripping was just as frequent. I would have thought higher voltage would have lowered the Amps drawn, and there would have been less frequent tripping. Can this high voltage (for a couple of months during construction) have caused the breakers to become prone to tripping? Voltage is now correct at both ends of the run. No run is longer than 75 feet or so from the main panel. 2) I kept the nature of the equipment back as it might cloud the issue a bit. Yes there is an inrush as this is studio flash equipment. That being said, there is no problem using this gear anywhere else in the city (I have been). Even the 15A on the stove is fine, but even a 30A SqD trips repeatedly. The units plug in with standard 16GA cords. I have changed the cords to 15' 14GA heavy-duty high-visibility (orange and black) cords mostly for visibility. The equipment repair technician says a transformer charges capacitors and only basic switches and so-on are between the line-in and the transformer. No capacitors directly connected to the line-in. There is a 'slow' setting (or gentle) on the unit for situations where the units must work on non-dedicated circuits that already have significant loads on them. This 'slow' setting trips as often as the normal setting. Again, they work everywhere else (on normal setting), even the stove outlet. 3) Counterfeit: I compared a breaker to the photos in the article. #C is not identical. Most of my tab is exposed, not 1/2 as pictured otherwise they match. 4) Multi-wire branch: I think so, 1 Neutral for 2 circuits. A single unit can trip a breaker or several units at the same time can trip 1 or more breakers in no particular pattern. My previous set-up was 12GA 3-wire BX cables with 2-20A sharing 1 neutral with no issues. 5) The breakers are QO type HACR 20A. 6) An ammeter was put on the units. There is a very brief peak over 20A. It measures between 28 to just over 30A. There was some talk about this brief peak measurement being unreliable for an exact figure. A cheaper meter read anywhere from 20A-38A. A better quality Fluke was typically under 25A. The 30A SqD trips with the same frequency as 20A so simply swapping to 30A (even in the short term) isn't an option. Thanks for your knowledgeable responses and effort to help with this. Tom
