man, I love the idea of this thing, but I keep getting WAY too much heat...
i started out at 15 amps with a 13 plate design -nn+nn-nn+nn-
or if you flip the leads its reversed...
and after about 15 minutes of running i start melting the pvc casing...
i cant keep the heat down, and then it starts to steam up, and I start loosing water which makes the amps go higher..
any ideas on how to get the heat down? i thought having all those neutrals would keep the heat at bay..
