New here! I have a Tesla Y Long Range coming soon to California. I am novice DIYer so will do my best to ask my electrical question below...
I need to install a 240V outlet in my garage and use a NEMA adapter for charging. I understand the difference between a 30A and 50A outlet and the corresponding 14-30 or 14-50 adapter, and how the charge rate is different.
I have an experienced licensed electrician that feels my total 100A panel (total for my house) is already pretty full with Air Conditioner/regular house things, and he would only recommend a 30A outlet for my EV charger b/c of this. Upgrading my total amp service is not possible at the moment.
I have another recommended licensed electrician who is convincing me that 50A would be okay b/c I'll mostly charge at night and other appliances are rarely used during those times. I don't think he is trying to upsell me or anything b/c there is not much of a cost difference, and he comes recommended from a friend.
I understand the situation and that either 30A/50A only ends up charging at 24/42A or so. I also understand you can adjust your Amp charge at the Tesla. My question is... if I decide on the 50A outlet and learn that the circuit is being overloaded (not sure the right terminology), would reducing the Amp charge at the Tesla be successful in adjusting the total Amps used? If a 30A (NEMA 14-30) uses 24A or if I adjust a 50A (NEMA 14-50) to use 24A - is it essentially the same? Or is the outlet still pulling 50A and if overloaded it will trip?
I prefer 50A obviously, but want to know if I can adjust as needed if there is a problem... or if I should avoid all risk and install it at 30A. Any thoughts or input appreciated!
