OK CW I understand your concern. Before I modify the ZW in any way, and while there's still a chance I may return it, I won't solder anything. I'm thinking I'll just clip a jumper across the breaker temporarily, start adding back load to the ZW, and watch the amps on a clamp meter placed over the jumper. I will see if my neighbor has one once people start waking up this morning, and if not, I will order one from Amazon. They've got it for about $25. Should be worth it in the long haul. If it is a weak CB that's tripping below 10 amps, I will replace it or have it replaced.
Thank you.
