A question for all electricity expert out there.
I am basically parking in my appartment building, in the basement. The landlord was kind enough to let an electrician install a dedicated circuit up to my car.
Basically the cord is 228 feet long (I know it is long) and 8 gauge.
I check the Voltage at my plug, when nothing is connected, using a Voltmeter, and it is around 210-211 Volt (so I am assuming it is a 208 V circuit?).
So here goes:
I plug to a NEMA 14-30.
When the charging it set at 15 Amps, the Voltage on the Tesla dashboard reads 202 V ish.
When it is 18 Amps, it reads about 200-201 V
At 20 Amps, it reads 198-200 V
At 24 amps (the max), it reads 195 - 197 Volts.
Are these acceptable loss? Can I charge over a long time at 24 amps without fearing that something wrong will happen?
What is the lowest "acceptable" volts reading?
