dedicated appliances, fridge, microwave, AC HWH etc. are required to have their own seperate breaker.
they may have installed a load shed device, which is OK by NEC when connecting two high current devices to one breaker. Likely when the microwave turns on, the HWH goes off temporarily.
Otherwise trying to run the microwave and HWH element on one even 20A breaker isn't likely to work.
Fridge and converter likely are ok by NEC. My converter and one set of outlets were on the same breaker. While it may be ok by NEC, a converter at full output doesn't leave but a few amps available for the outlets. I moved by converter to it's own breaker to free up a full 15A load to the outlets.
no longer complies with NEC, but still IMHO safe, even safer, and less likely to result is unwanted trips.
