BTW I have the same unit, used it for almost 4 years, and probably approaching 300 days. So far it has performed wonderfully, although yes it does get warm (not hot). In fact this weekend it alerted me to a intermittent open ground at the pedistel.
Mine performed flawlessly for 6 years. The only problem it found though was when I used my portable generator. It seems the generator has a floating ground, and the unit doesn't like that. If the processor is generating some heat, that is to be expected. But, heat from high resistance in the main line IMO, should trigger a shutdown. It protects you from a defect in the source, it should also protect you from it's own internal failures.
common problem with generators, and PI has three solutions. The one i use is to make a "shorting plug" for the generator. a plug wired internally with ground and neutral tied with a piece of #12 wire. I plug that into the generator and now no "open ground" fault.
BTW this last weekend we were at a RV park and on the second day the EMS started giving me a "open ground" fault when AC turned on. turned out the pedistal did have a bad ground, plugged into the next site service and all was well.
