The problem lies with the second set of heat strips kicking in when it gets real stinkin’ cold (which btw is how it’s supposed to function) and we’ve lost power and are running off the generator. To reiterate, I slapped a Fluke clamp meter on the ATS and had the Mrs switch the largest unit to “emergency” which forced the system to run only on the two sets of heat strips which is exactly what happens when it’s 5° outside and the utility power is out. Turns out just that one unit draws around 82 amps which don’t leave much for the rest of the house. <img class="smilie smilie--emoji" loading="lazy" alt="😉" title="😉" src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f609.png" /> Thankfully I have a solution. Ty was kind enough to help me think through the wiring diagram and I was way over complicating things which I’ll blame on all the bad information I was getting from a couple HVAC techs. All I have to do is open CB2 and it will disconnect that pesky second set of heater strips which I’ll only need to do when our utility power is down. Easy Peasy. Thank you yo all for your help in finding a workable fix.</p></blockquote><p></p>
