At EEman's suggestion, I Finally, finally, FINALLY(!) today I completed a dedicated 15A line to power my low-draw gear. Key install point: the two dedicated lines are NOT on the same leg coming off the pole.
I unboxed my Outlaw, long back from repair in October. Along the way rearranged some gear & cabling, thoroughly cleaned everything, plugged in the H15 & connected it all.
Unfortunately by the time I finished, it was after 11pm!
Tomorrow I'll run a couple of tests then I enjoy the fruit I've, for so long, waited to taste, and ask God: please no more failures.
Merry CHRISTmas, Tony
