Correct they are sized (amp rating) to allow for inrush current on the entire panel but this person is adding a 60 amp circuit for a charger thats going to be drawing 50 amps. Add in all appliances and other devices in the house plus 2 ac units.

Breakers can handle inrush current of startup for a split second period of time. The two ac units, if starting up at the exact time could cause it to trip. It does happen, albeit not all the time. The 5-7 times the rated amperage is based off the nameplate data of the ac unit, not the breaker. Dont know how you thought i meant that.

I dont know what your point was other than to try to say I dont know what Im talking about. Sounds like you know enough to be dangerous.

41 amps between two AC units and the rest of your house? Highly doubt thats correct. Its also the inrush current that you have to consider. Your AC units can draw 5 to 7 times their rated amperage on startup. Add that with your charger and everything else in the house and you can trip your main.

You'll likely need to upgrade your panel and service to your house. Adding a 60amp circuit on an already full panel is going to probably put you over the main circuit breaker limit, guessing you have 200 amp service.

You have 2 air conditioners. Your entire house lighting and outlets. Utilities (washer, dryer, dishwasher).

Adding a 60 amp circuit is probably going to be too much.

Hire an electrician to make sure you dont overload your panel an risk tripping the main breaker. You dont want to trip your circuit breakers and bust your 200 amp main. That'll be an expensive fix.

Reply to How do I ground new outlet run from here? by Baldar538

The outlet has a ground connector in your first picture, the bottom right.

That should be connected to the new ground (green) wire in the flex whip. You can wire nut all 3 together and zip a screw into the conduit box for even more protection, being the conduit as a pathway to ground to your panel.

True, flex conduit should not be used as a path for ground, hence why there's a ground wire included in the whip.
