I know you are. Concerning his claim of costs, and the 'overloading' of most service entrances, I agree with you. His figures for the length of time to charge the car is correct, however.
As I said.
Yes. I am aware of that bit in the code as well. Depending on the appliance there, you must also provide iron or concrete posts to protect the appliance if it's permanently installed.
I was unsure about that. Thank you. Some jurisdictions have this additional requirement beyond the NEC.
The 'service disconnect' is pulling the meter on many houses built in the 70's. The other is pulling the fuse on the transformer. Your particular jurisdiction may be required it that early, but not the NEC at the time. It's in there now, of course. Quote sensible!
Nope. Not always!
Yup.
Tesla charging stations can be switch for different charging rates. The installing electrician can set this switch to any of several choices. The user can't.
True.
That's about right. They also draw differently depending on whether it's a 120v or 240v welder.
That nameplate is required on all welders.
That it does! Fortunately, that sort of thing tends to occur in businesses where a larger service entrance has been installed.
That's about right. It's usually more, depending on the extent of the modifications required or desired by the end user.
Indeed it does!
The trenching itself has new requirements too. There are expanded clearances required between electrical lines and gas, sewer, communications, and water lines, and the warning tape is now required. Depth requirements haven't changed though.
Very true. It can add up, if some other building or tree changes the routing path due to clearance requirements to get to the weather head.
