Hello all,
I recently bought my first Tesla and am delighted with it. Model three RWD.
I also bought a gen 3 wall connector which I have had installed by an MD licenced electrician. As part of this I had a permit pulled and today it failed inspection.
I have an older house with aluminium wiring and a 50A breaker. The reason given for failing the inspection was that the wall connector was direct connected to the 50 amp circuit (properly) and configured in the firmware to only charge at the de-rated 40 A (properly) but still had a sticky label on the side of the wall charger which said, among other things
Input: 200-240 ~48A 50/60Hz 1 phase and ,
Output: 200-240 ~48A 50/60Hz 1 phase.
The inspector said he would clear it if the sticker was replaced by one which said 40A. I should just get one from Tesla, he said. Other third party suppliers enclose a set of such "de-rating' stickers in their boxes apparently. OK, I thought....no big deal....except I could find any of these stickers in the Tesla box in which the wall connector arrived and I cant find anyone to ask and without a part number of this new sticker even the service department can't help.
So it seems that there is no discussion about whether the installation was done right (it was), or that the equipment is not up to code (it is), but just a matter of announcing, presumably, to the next house owner that it is derated to 40A on purpose.
As a relative newbie Tesla owner I feel that there should probably be a solution for this. Maybe a remote service event by Tesla which could set something in the firmware to trigger the issue of a new sticker arriving by mail.
So the question is whether anyone has confronted this and found a solution/workaround.
Thanks in advance.
