Both AC and DDC need a ground or a neutral to complete the circuit so the electricity can flow. When it comes to DC voltage if you power a device from a separate transformer other than the transformer that is creating the DC bolt signal you need to common both transformers. Splice both of the transformers together for the device to have power and control signal if that makes sense.
Nice job on that find. It’s easy to overlook the simplest of solutions.
thank you, always start simple. 9/10 times is the basics that people tend to overlook
Good find on that one
Thank you. Calls like this can be tricky
I was confused at fist but it started making sense. DC always needs a ground unlike AC voltage right?

@@professorbutlerhvac thanks!
Check phasing with your meter, then just tie commons together. You still mostly get the benefits of isolation but no common fuckery.
You are correct. Good thinking. Thanks for the info
I need to study with you online. Is that possible. Can you send me your email adress?
