Hi Fellow Tesla Owners! I just have a quick question! So I live in an apartment and they only have NEMA 10-50P wall sockets, I tried to get an adapter from 10-50P to 14-50R but it was getting a fault. I did read in the manual to not do this. Could that be the reason? If it is, is there a way to by pass it because I would not be able to charge it any other way besides hitting up super chargers which I do not really want to do. Thanks and have a good day!

I have used my 10-50 to 14-50 several times without problems. A 10-50 does not have a ground, only a neutral.
You can test your receptacle and dog bone with a basic electric meter. Each receptacle should have two 120v sides and one 240 side.
If the wall mounted 10-50 does not have any 120v sides, it is miswired. A welder could use a 10-50 and not know the neutral was disconnected.
If the wall is fine (probably is), test the dog bone. If there is no 120v to ground, the ground was not connected to the neutral.
It’s possible the dog bone isn’t wired correctly for charging. The car tests for a ground before starting to charge.

That was the fault. I got the adapter that pnwadventures linked and that one worked just fine. It stated in the owner's manual that they don't recommend using an adapter. I didn't know there was an actual adapter for it until i got the link which was why i tried that.

There isn't - it's aftermarket, but done right. IIRC they take the chip out of OEM adapters and re-create a quality aftermarket one. Blanket statements like "don't do this" by Tesla are aimed at the disinterested masses. Doing a little bit of research to understand what's going on goes a long way. I recently moved into an apt as well (sigh) and will be hooking up a 10-30R to a 10-30 + 14-30 Y-splitter + 50-foot 14-30 adapter. Using the dryer outlet. fight me irl

Damn good luck with that, it sounds like too much work for me. LOL

Never too much work for the sweet, sweet electron juice…not having a way to charge at home would be a non-starter for me.

Same here. I was en route to selling the car - luckily I figured it out because I didn’t really wanna do that. We went charge-less at home for a few weeks and it’s a serious PITA, at least there I am. No way in hell I’m paying $0.40/kWh for Level 2 charging.
It’s super simple, in the end. Basically all I’m doing is this:that is true but mine is already settled so i don't wanna give my self a headache thinking about all that

So there's a shortcut. Take a hacksaw to the 10-30 adapter (which Tesla sells) and trim the L off. Now it will fit into 10-30 and 10-50 outlets! Or order the EVSEadapters unit.
FYI A 10-50 or 6-50 extension cord is cheaper than a 14-50 cord because it has one less wire in it!

Cutting the neutral off a 10-x won’t let the car charge because Tesla requires a ground.
Perhaps you are thinking of a 14-x where the neutral has no function charging the car.

10-50 and the wire (Better be 004 Copper NOT Aluminum for Tesla Charging) is different from 10-30 in that the Breaker is a 50A for the one and 30A for the other. I think the onboard charger draws less than 15A so the most likely cause of an error would be what doghousePVD said about making sure you have ~120V on the two hot poles of the outlet (WARNING: BE CAREFUL! DON"T TOUCH IT UNLESS YOU KNOW HOW TO PROPERLY USE THE METER). If you do not, have a qualified Electrician or Electrical Engineer troubleshoot to make sure you have good contacts from the outlet back to your service and get those tightened down if that is the issue. I've see the electric providers supply minimal voltage (i.e. 219v or less) where you should see within the range of 118-122V and both sides of the outlet should be within 2V of each other.

Haha, I'm down with the Y-splitter - janky ground wire and all. It's only pulling 24A which is just barely more than a few strings of Christmas lights.
Not so sure about the UMC thrown into the garden box though. And is the cord tucked into the groove of a public sidewalk? You sir have an enviable mix of patience and optimism.
