Unfortunately many local licensed electrician does not aware about it. They read US code requirement to install disconnect switch if "more than 150V from line to ground" as requirement to install disconnect switch before Tesla Wall Connecter, because it uses 240V. But actually it is two "hot"...

In US we use one split phase 115V , 115V and ground. So Tesla Wall Connecter uses 230V. Breaker on both "hot" lines is 60Amp, but Wall Connecter uses 48Amp. As result disconnect switch should support 230 x 48 = 11 Kw =15HP

If I understood correct, in US Tesla Wall Connecter uses split phase (115V each hot wire) and ground. Wall Connecter provides maximum 230V x 48 Amp = 11Kw = 14.8 HP. This is why Disconnect switch rated to 10HP is not correct solution and cause to that I showed in previous post. If you installed...

You are right in BOTH sentences. I replied on old post because I found it the most relevant to my issue and I saw that people set $20 disconnect switches and after this surprised by seeing attached picture. Regarding the 150V code requirement, you are absolutely right. I had a misguided haze...

Yes, Tesla Wall Connecter uses only 48 Amp, but 230V, so it is "more than 150 volts-to-ground". And, according to your quote, the disconnect switch is required.

My local Tesla electrician and Permit guy both called Tesla Wall Connecter as EVSE. Why it should be not call like this and how the "Tesla Wall Connecter" should be named ?
