If you like, skip down for the key question...

BACKGROUND INFO:

THE KEY QUESTION:

(FYI: My memory says no.) THAT information will help me to decide exactly how to configure what circuits and conductors go where.

FYI:

Below is a single phase chart for those of us in the U.S. who do not have three phase, like many in the EU:

First column is the Ampacity of the EVSE device.

Last column is the required Ampacity of the CIRCUIT that the same device should be on.

[{10A x 240v = 2.4kVA (Watts)} x 1.25 = 3000 VA] / 240v = 12.5 Amps

[{20A x 240v = 4.8kVA (Watts)} x 1.25 = 6000 VA] / 240v = 25 Amps

[{30A x 240v = 7.2kVA (Watts)} x 1.25 = 9000 VA] / 240v = 37.5 Amps

[{40A x 240v = 9.6kVA (Watts)} x 1.25 = 12000 VA] / 240v = 50 Amps

[{50A x 240v = 12.0kVA (Watts)} x 1.25 = 15000 VA] / 240v = 62.5 Amps <=====<<

[{60A x 240v = 14.4kVA (Watts)} x 1.25 = 18000 VA] / 240v = 75 Amps

[{70A x 240v = 16.8kVA (Watts} x 1.25 = 21000 VA] / 240v = 87.5 Amps <=====<<

[{80A x 240v = 19.2kVA (Watts)} x 1.25 = 24000 VA] / 240v = 100 Amps

[{90A x 240v = 21.6kVA (Watts)} x 1.25 = 27000 VA] / 240v = 112.5 Amps

[{100A x 240v = 24.0kVA (Watts)} X 1.25 = 30000 VA] / 240v = 125 Amps

My favorite "West Wing" quote (Ep. 1-18): from Sam Seaborn: ==========

BACKGROUND INFO:

In previous years, I have pre-installed:

two 1.5 inch pre-installed PVC conduit(s) going out to the detached garage on the north side of my driveway (length forgotten, but likely

*more*than 100 feet)and

two (one still available) 1.25 inch PVC conduit(s) going to a post on the south side of my driveway (length forgotten, but likely

*less*than 100 feet).

I also have (100 feet each of) *and***#6****AWG conductors ready to install for two circuits in one of the conduit(s).***#4*(AWG or kcmil) 60°C (140°F) 75°C (167°F)

6 AWG 55 65

4 AWG 70 85

[The 2nd pipe at this location already has a NEMA 14-50 & a 50 Amp circuit installed for the 2nd unit.]****~~What I do NOT have is the circuit breaker, or a decision as to what Amperage said breakers should be at. ~~

[CORRECTION:

It looks like I stopped this project after I had purchased a 50 AND 80 amp breaker(s).

I presume the 50 Amp (but probably NOT the 80 Amp.as well) will need to be exchanged for a GFCI version.]

*{Note that I _*

__AM___ aware of NEC's TIA 17-2 for Articles 625.44(A), 625.54(New) and 625.56(New)}

Yes, I do know the 2nd version of the Tesla Wall Connector could handle a 100 Amp circuit for 80 useful Amps and the 3rd version can only handle a 60 Amp circuit for 48 useful Amps.

However, I am more interested in finding out...

THE KEY QUESTION:

** Has Elon (or anyone else) stated (or can anyone deduce) how many 240v single phase Amps or KVA the Cybertruck's on-board Charger can handle?*(FYI: My memory says no.) THAT information will help me to decide exactly how to configure what circuits and conductors go where.
