Perhaps if you actually visited his Playa Frambes Lighthouse Resort, you would appreciate Bob's opinion just a bit?

As a retired 30+ year EC doing multi million $ projects, ah no. His opinion is just that, opinion. Doesn't make it correct.

I did use the word "opinion"... 'Respect' is perhaps another word that goat might benefit from?

You got to be humorless if you don’t see humor in bob spouting off on the internet, and simultaneously telling readers to not trust anyone else
spouting off on the internet.
I am sure Bob is very accomplished, but he is also often very wrong so needs to be ribbed!
Dk, is that lighthouse wired with 110 or 220? 
Woke!

On a car or MC the electrical circuit is normally 12 volts which would be a hot wire (12v) and ground. On a 220v circuit for a dryer for example it is
two hot wires. 110v of one phase and 110v of the other phase thus 220v. No common needed. A ground is needed to ground the case or frame or whatever
so you don't get electrocuted.

I can't believe you guys are still arguing about this btw this willard fellow is
absolutely correct on all counts.

No common??
3-hole 220 outlets have 2 hot wires, 1 common wire, and recommend powered device to be grounded separately.
4-hole 220 outlets have 2 hot wires, 1 common wire, 1 ground wire.

like has already been said here the only time a 220 circuit needs a neutral is if a 110 volt circuit is needed......you guys ever hear of "google"?

Interesting, I've changed out the receptacles and switches, but never really delved in to 110/220 systems. I'm an auto and moto wrench. I'll have to
do some research just for some new knowledge. It can't be that complicated. Probably less so than wiring two switches for lights.
One issue that may come up is whether the panels in our townhouse development can be modified to charge electric vehicles. My neighbor has a Tesla
but charges it at his work. Since he's a renter, I haven't asked him about upgrading the electrical. Perhaps our homes can't support the load
required for an EV. My flat garage roof is oriented exactly north to south, but I do not think the HOA has approved solar panels, or I could produce
a chitload of electricity.

John,
Non-Tesla car chargers come in 3 levels currently.
Level 1 is 120VAC 15A draw
Level 2 is 220VAC up to about 50A
Level 3 is not going to happen in BCS soon as it would black out Cabo!
Teslas have destination chargers which are similar to Level 2 chargers.
There are adaptors to allow Teslas to use level 2 chargers.
I don’t know if Tesla owners get a level 1 charger with their car. I have heard not any longer.
Some cars allow you to adjust the charge current in software in the car setup menu.
We have ours set to draw a KW of excess solar.

Personally, I'm not looking at an EV, but the electric demands are something to at least be aware of. Thanks for the information.

We've stayed at Bob and Susan's place. It's very cool. We anchored our boat right off the beach in front of the light house.
Did some runs deeper into the bay for dinner and drinks.
Susan is pretty sexy.

My Tesla came standard with the 115vac power cord which is very slow but for anyone who can leave it connected all night it works OK. I bought
Tesla’s 240vac power cord for about $500 two years ago. On my garage 250vac circuit it charges at about 40 amps which is about 38 to 40 miles of
charge per hour of charging at that rate. Teslas super chargers are much faster but they cost a lot more if you want the faster charge. Tesla also
provides an adaptor to use on the other EV style charging stations.My home power costs 6.9 cents/kWh with my reduction for solar installation. The car
battery is 62kwh which is about 250 to 300 miles. With present fuel prices EV’s are looking pretty good. It remains to be seen what the huge flood
of EV’s on the road what will happen on the freeways when there is a power failure? Lots of stranded cars blocking traffic.

Oh good, an EV owner, I don't know any.
1. If broken down, can your car be towed or does it need to be carried? Does that vary between different manufacturers?
2. I understand Teslas don't come with spare tires. Is there someplace to carry one if you wanted to, besides the roof and interior? Is changing a
tire any different than a gas vehicle?
3. Is there a problem if you have to wait in a 3-hour borderline that's creeping along? I suppose you would need to turn off the A/C eventually.
4. Does the car slowly discharge just sitting, not being used?

Off Topic lite?
You never know which post will get legs and run for page after page. The O.P. never asked for any advice, he just wanted to let others know about an
unsatisfactory experience with a supplier he used.
Here we are, four pages later getting an education on 220v circuits!
So how many solar panels will the O.P. need to install on his RV to power a 220v outlet?

It depends upon whether or not they are using the dishwasher, clothes dryer, toaster, and vacuum cleaner in the RV at the same time.

Tesla states it must be towed. However, some owners report towing Teslas with no problem. Not being familiar with other manufacturers I would think
the battery re-generation caused by the electric motors
pumping power unregulated back into the battery could cause problems with the electronics which is what Tesla is concerned with.
2. I understand Teslas don't come with spare tires. Is there someplace to carry one if you wanted to, besides the roof and interior? Is changing a

The tires are small enough to place in the trunk or possibly in the hood cover.
3. Is there a problem if you have to wait in a 3-hour borderline that's creeping along? I suppose you would need to turn off the A/C eventually.
Short answer, yes. And if you run down the battery in those conditions you have a problem. There have been Teslas seen arriving at charging stations
on a flat bed tow vehicle.
4. Does the car slowly discharge just sitting, not being used?
There are some parasitic current draws that could run the battery down eventually.

Are you sure about that? A google search says otherwise but there is some mixed info? That's why I asked.
Many links say an EV must be trailered, not towed. This is copied from the Tesla Model 3 Owner's Manual (I didn't add the "all caps"):
"NEVER TRANSPORT YOUR VEHICLE WITH THE TIRES IN A POSITION WHERE THEY CAN SPIN. DOING SO CAN LEAD TO SIGNIFICANT DAMAGE AND OVERHEATING. IN RARE CASES
EXTREME OVERHEATING MAY CAUSE THE SURROUNDING COMPONENTS TO IGNITE."

While doing a Baja run last year, I had a house sitter taking care of things. His car was a P.O.S. Ford hybrid that was only produced for a couple of
years.
I won't go into the multiple failures he had with that car, but it had to be towed with all four wheels off the ground!

Thanks for the reply.
I just bought a 2023 gas SUV. I considered an EV but these concerns stopped me (not to mention the charging issue) since I'm in Baja for months at a
time.
