What you are looking for is a brown or black square lid that has a plastic "knob" you need to use a coin or screw driver to turn the knob and pull the lid down.
Once opened you will see the braker switches and also the fusees, the braker that poped is going to be feel losse, turn the air conditioner off as well as the refrigerator, tv, inverter, any shore powered utensil, now turn the brakers all off and then turn them on, then turn the fride on and then the air.
