Tesla Wall Connector (HPWC) UL Certification?

Tesla Wall Connector (HPWC) UL Certification?

I am trying to get the permit for my newly installed Tesla Wall Connector (previously known as High Power Wall Charger). The installation instructions provided in the box do not mention a UL rating for 240v. I also tried searching the UL database and only saw 3 certifications in their database for Tesla Motors and none of them were for the wall connector. My city refuses to permit my installation without proof of UL certification rated at 240v. My electrician has installed dozens of these and never run in to this before, so we're all a bit baffled. Where can I get this info?

Why bother with permit?

I'm not going to argue with you about whether or not to get a permit. If something were ever to happen with the car and the wall charger was to blame, the first thing Tesla would do is blame the installation. When you get a permit, you're avoiding that argument entirely. You have proof from the city inspector that everything was installed properly and to the exact specifications required.

As for UL being a private lab...I know. Which is why it was particularly perplexing that the city refused to issue a permit without it. The guy was an ***hole, I don't know what else to tell you.

Won't Tesla give you the info?

No response from Tesla yet, was just wondering if anyone else had the info. But I guess my city is so weird that no one else has ever had this problem before? :(

Go back to the city and talk to a different guy. Or look up the code (or have electrician do it) and see if UL cert is a real reqt. By that logic it would be illegal tonplug a non UL certified gagdget into the wall.

Chance of a problem (fire) is VERY low.

If the HPWC is UL rated, then it will have a cable tie marker around the cable somewhere near the bow end or the connector end. The standard is to put it within the last 6 inches from the ends. This tie marker will have the UL label and other writing on it.

I meant box end, not bow.

The installation manual shows that it is UL Approved. See page 2 under agency approvals. As stated above UL is private company. Local or state laws generally require approval by a Nationally Recognized Testing Laboratory (NRTL), not UL specially. UL is a NRTL as is FM CSA-US, ETL, lots of other testing labs also meet this requirement as well. Manufactures can go to any of these NRTLs to get their equipment approved. The approval should satisfy the local inspector.

Additionally I would like to point out that the US model is "120V ABOVE GROUND" not 240 volts. The voltage is 240 volts between the two legs supplying the power but the voltage to ground is 120 volts on each leg. Is the rating for 240 volts the area of confusion?
