Yep quaility is important to us by Keystone. In the metal junction box coming from my 5500 Onan the wires got so hot that the only thing left of the wire nuts were the metal inserts. The junction box was so hot it would burn your fingers if you touched it. I had to prune off 4"/6" of wires and then reassemble. At least there is no more burnt plastic smell when using the generator. Glad you found the water heater issue before you had a fire.
