is it worth spending some $550 to install surge protection as 240V power is laid into the garage in preparation for new garage doors and an eventual M3?

Are you in an area that has power issues?

If you do just make sure it is rated to handle the voltage and amperage of at least a level 2 charger. If you can wait until next year we should know more about the charging requirements for Model 3.

Thanks for the swift response, TrevP! We have an almost annual power outage on our side of the street. Otherwise no problems. The guys are here today putting in a NEMA 14-50, etc., and can add the surge protectors (one for whole house and one for garage) today or later. Up to us.

I saw garage doors connected to 240 vac before. It was absolutely hilarious how quickly that motor moved those doors!

I obviously don't know your situation, but here in a suburb of Northeast Ohio it cost about $400 to have a whole home surge protector installed. I trip is once a quarter to make sure it works. It works!

A company came out with a surge protector for the Model S and asked me to review it. I called Tesla and asked them about the issue and if I needed to worry. They told me that the Model S charge cable is protected from surges and surge protectors are completely unnecessary. I declined the review.

Thanks very much for the news! My electrical contractor wonders whether all the Tesla charge cables protect the vehicles from surges. Do you have contacts who would know?

The Model S (and Model X) UMC that comes with the car (in North America) adjust to the types of plugs and supply to limit the charge. It is smart enough to see the load and adjust the rate downward.

For example, on our cross-country trip last year, when I spent time at my cousin's house (day 10, day 14, day 15), the 110V connection worked at 1 mile per hour originally and finally found the sweet spot at 2 miles per hour (not the 4) because of the quality of electrical connection that he had (it was the longest run in the house.)

This capability was added after some of the much publicized Tesla Model S "fires" from years ago. (It's important to note that some of the UMCs sold in Canada are sold restricted to 30A, I believe (even with a NEMA 14-50) to comply with Canada's electrical authority or standards, (I'll have to see if I can find the source, this is years ago, I believe)).

Not sure what you're asking. I asked Tesla directly and they said a surge protector is not needed.

Found the email:

Thank you for contacting Tesla Motors Technical Support. The Model S has protections in place built into the cable as well as the car to avoid any issues with electrical supply. The car is very smart and will protect the battery and charging system from any outside influence."

OK, found the discussion on TMC about capping UMC in Canada (apparently 32A, not 30A)

Received some very helpful information from Tesla Home Charging Installation expert:

"All Tesla vehicles have built-in surge protection, so it is not required. That being said, there is no real protection against a direct lightning strike. The door motors probably don’t have built-in surge protection so it might be a good idea for those.

Please let me know if you have any questions.
