I saw this earlier and was actually interested. I know there was another thread on phasing of transformers and yes I would be interested in understanding why one plug is bigger than the other, which I think relates to the phasing.
I don't get the snarkiness of some of the replies. It's a pretty fair question and I just wonder how you might feel if your question were answered with a how could you be so dumb? I like the forum for all the great help that I can get. Perhaps it's just all that is going around in the world, but some element of kindness isn't such a bad idea.
