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?

Some of them were tagged GFI - does that refer to protected outlets in the circuit?

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.
