Ok folks, This may be a silly sounding question, but I was asked this yesterday and I really don't know the answer. We all know that AC outlets, most quality extension cords and AC junction boxes are designed for plugging in plugs which contain a ground tip AND designed fitting for a small & large prong. However most Wall Warts (example) Dunlop ECB03 & ECB04, only provide 2 prongs to plug in (No Ground tip) AND both prongs are of equal size. As another example, IF you have 3 wall warts being plugged into an AC extension strip built to handle 6 input plugs, does it matter that all 3 wall warts be plugged in the same way (direction) OR does it matter if one is plugged in "upside down" compared to the other two?? This is a question I've wondered about as I have seen many players plug there warts in any manner just to get as many warts as possible on a strip. Is there a "rule" that should be followed, or does it make no difference??
