You can not use a small extension cord to supply heavy amperage load to things such as your air conditioner because it’s like using a tiny tube trying to supply a large volume of water when you really need a large hose or pipe. You will burn up the cord or the appliance because the tiny wire creates too much resistance which won’t allow enough power to get to the appliance.

Yes. As I am learning. Luckily, it looks like everything is functioning correctly and that the breaker on the house outlet tripped early on.
