Plug and 100Amp line sticker shock

[mitch672]

The 6/3 & 18/2 custom EVSE cabling alone is about $9/foot (cable is ~20 feet long), then there is the custom Tesla connector, and the other end with the interchangeable plugs, then 14-50 adapter, the 120V adapter, the electronics box, and don 't forget the retail markup. $750 is actually reasonable, if that's what the number is. Checkout some of the standard L1 120V portable J-1772 EVSEs at Lowes and Home Depot, $800-$900 is the norm for a much less capable EVSE

I just paid ~$3000 for a 70 amp Eaton EVSE $750 sounds like a bargain!

Call me a Boy Scout if you will, but I want one that stays in the car 24/7.

I'm with you on this one.

I keep a set of jumper cables in the trunk of every car I drive as well. Similar reason.

I have no idea what that means or what to do with it.
and you guys are probably right...but I'm just itching for that HPC as my 'main' charger and to keep the UMC as my backup/keep in car. I'm not saying it's logical, smart or necessary...but neither is the leather interior, Tech package or the upgraded stereo!

I have decided to get the HPC and run a 50 amp line to it. Will get a single charger for the car since a 50 amp line will not charge the car any quicker with twin chargers than a single charger.
Since I'm retired and don't do that much daily driving, this should work fine for me.
It also lets me keep the standard connector cable always in my Frunk for whenever I might need it on the road.
We also have a second ICE car for whenever we want to take longer drives than I'm comfortable taking with the S, for now.
And of course most importantly, the HPC just looks cool!

Much similar to my logic as well. I want that 100amp twin charger option "just in case", but that's likely going to be very rare/infrequent.

My electric panel box is in the garage. It's about 8 feet away from where I want my outlet. Here's my parts list for a NEMA 14-50 installation:
- 50A Cutler Hammer breaker $12
- 50A Outlet $10
- 15 ft of 6-3 cable including ground ($2.61 / ft) $39
- Outlet box $4
- (2) clamps $2
- Sheetrock, sandpaper, tape, mud, screws, touch-up paint, roller, etc. $30
- Wall mount bracket to keep the Tesla cable off the floor $10
Total was about $110.
Less $50 Home Depot Gift Card (from Christmas)
Parts Total $60.

Recommend you also pay the minimum charge to have an electrician check your work and/or make final connections ~$75.

HOWEVER, if my panel box was on the other side of the house (as some people mentioned), I would probably go with a NEMA 14-30. The wire for a 30A circuit is a lot less expensive than for a 50A circuit, and the cost quickly adds up when you are buying lots of wire. The wire you would be using for a 30A circuit is also a lot easier to work with. Also, whether you go with 30A or 50A, you will most likely still have a full charge by 7am. The 30A circuit gives you 216 miles of charge in 12 hours.

Thanks for all the good advice on home installation. Hoping a couple people have thought about on the road (emergency) options with the Model S, dual charger. Is it possible to use the dual changers with 110v each plugged into 2 outlets and decrease charge time? Anyone done the math for this, if it is even possible? Ratios in hours would be good- (2 110v outlets= 20 miles in 1.5 hours vs 1 outlet= 20 miles in 7 hours, etc).

See this thread here: http://www.teslamotorsclub.com/showt...om-110-voltage for getting 220 out of two 110s.

You still won't need the second charger, as 220 at 16 amps isn't much.

Depending on where you're located, you might have an easier time finding J1172s at 30 amps. However, there are more J1772s in my home town of less than 30K people than there are in some entire US states!

No. It's not possible because there is only one charge port, so only one electrical connection can be plugged in at one time. The second charger just allows a higher capacity circuit to be used. See the calculator for details.

Thanks. This is good info! Figured it had been asked before just didn't see the prior thread.
