RCD (aka GFCI) breakers?
Based on the photos earlier no, they look like standard north america breakers.
-
Some of them were tagged GFI - does that refer to protected outlets in the circuit?

Here in the UK you can get RCBOs, which combine a current breaker with a RCD (aka GFCI). Might it be one of those?
EDIT: the ones with TEST buttons are RCBOs.

I had an instance with one of my printers where the IEC connector fuse would blow after 10 minutes.
At first I thought that the fuse had died, but after 2 additional fuses died, I replaced the fuse again and
monitored the printer while powered, at that moment I realized that the IEC connector was getting really hot!!! (It was a crappy chinese one, bought via Amazon). After replacing the connector with a better specimen, the problem was solved, for some reason there was a bad connection inside the connector causing sparks and resulting heat.Long story short, check your IEC connector (and get one with a fuse)

One of the IEC connects were questionable to say the least.

@bearer just removed the bed wiring all together, so no power is being drawn in from the bed. Breakers still blew. Again not sure what my issue could be?? So strange that this thing could be drawing that much power!
Here’s a pic of my breaker terminal if that help!
Which of those breakers trips?

Yes. In North America any ground fault protection is typically present in the socket at the point of use rather than at the breaker.

Some of the breakers illustrated have TEST buttons. Those look like RCBOs (combined current breaker and GFCI) to me.

@dc42 That could be.

It doesn't make a whole lot of sense to have the full rated breaker current as the fault current without being able to see/hear/smell it to me.
