David, we are all good people here, and every now and then, some almighty powers come along and put us to the test.
We truly hope you enjoy your hot tub, but your perception of others who dare to contribute seems to come to you only the way you see it to be.
In as much as I had only one post, here in this thread, it appears you totally misread, misunderstood, or misinterpreted my post as demeaning.
I don't believe any of us represented ourselves as "experts" on the subject of your concern, as none of us are electricians. So this must be your perception of thinking of us as experts, even though, it seems to be the perception of others that maybe you should do what you advocate, and have a happy day.
