Model 3 Charging Hubbell HBL2810 Receptacle

Hi,

I have an electric vehicle charging outlet in my apartment building parking stall but I’m trying to figure out which specific plug or set of adapters I will need in order to charge my 2019 Tesla Model 3.

The building manager informed me that the outlet is a Hubbell HBL2810 (Hubbell Locking Devices, Twist-Lock®, Industrial, Flush Receptacle, 30A 3-Phase Wye 120/208V AC, 4-Pole 5-Wire Grounding, L21-30R, Screw Terminal, Black). Here is a link (https://www.hubbell.com/wiringdevice-kellems/en/Products/Electrical-Electronic/Wiring-Devices/Locking-Devices/Insulgrip-Twist-Lock/HBL2810/p/1638272). I've also attached an image of the receptacle i'm trying to use if that is helpful.

Can you please let me know which Tesla adapter I would need to purchase in order to utilize this outlet? Or if you have third-party vendors you’d recommend to buy or build an adapter and plug from? I would like to be able to have this adapter shipped to Canada.

Any help would be greatly appreciated. I'm a bit novice at electrical connections so I'm trying to be very cautious.

you’ll need two adapters. One to adapt the L21-30 receptacle to an L6-30, and then an L6-30 plug for the Tesla Mobile Connector.


And then this one:


But that’s it. Should be very simply plug & play for you!

Just for yuks, you might want to contact www.evseadapters.com to see if they'll make one direct from L21-30 to UMC, either just for you or as a new product.

Also note that your charging will be slower on this plug since its only going to deliver 208V typically instead of 240V. Probably not a big deal for you, but thought it worth mentioning.

Thank you very much for the help! I'm definitely going to look into purchasing these 2 adapters as well as the other poster's suggestion of asking whether a custom adapter could be ordered from www.evseadapters.com.

I'll send an email to www.evseadapters.com to ask for sure. I was also looking at www.ironbox.com to see if they had an adapter like that, but I don't believe they would custom make an L21-30 to UMC. Also thanks for the heads up about the charging speed, it is definitely enough for me!

Thanks again for the help everyone, I appreciate it!

Glad we could help! Keep us posted what the final configuration looks like, but you should have no problem getting a decent charge off that receptacle. You should see somewhere around 22-24mi/hr when charging Model 3… for most of us, that’s more than plenty.

Whoa, yeah, you managed to surprise me. I've been around this forum for something like 6-7 years or so, and I think that's the first time I've seen that someone has an L21-30. EVSEAdapters are great, and I do think they would build one if you asked.

Hi,

I just wanted to follow up in this thread to mention that I had sent an email asking about my specific adapter needs to evseadapters as suggested in this thread and they gave me this link where I ordered the adapter I needed L21-30 Twist-Lock Adapter for Tesla Model S/3/X/Y Gen 2 – EVSE Adapters. I ordered and have used it a few times and it works just as I need!

As someone warned me earlier I just get about 200V with my setup which is more than enough for me. Thanks again for all of your help in this thread I really appreciated it!
