NEMA 14-50 installation cost and code requirements?
My contractor is telling me I need a cutoff between the Jbox (already ran the 60A/240V wiring to the garage) and the 'charger' and that this would cost $600. Anybody else get this response? I was told this is 'code' but I read the Seattle electrical code and could not find the requirement.
I would have thought the cutoff is 'pull the plug out.'
Anybody have an electrical contractor they liked for installing the NEMA 14-50 in Seattle?

The cutoff is the breaker in the panel. Question is how far away is the panel? Mine is about 8 or 10 feet, so it can be reached easily enough.
On a hot tub you usualy need a cutoff within x distance of the tub, but no more than x distance away.
Call the inspector directly if you like.
So you have no breaker in your main panel for the NEMA 14-50 wire run? If that's true, then I believe this is not only a code violation, but extremely dangerous. A short circuit will cause your wires to heat up and melt - possibly causing a fire. The purpose of a breaker or a fuse is to prevent excessive current in the wire from causing the wire to overheat.
Anyway seems like a good way to go so the extra bit of money is worth it for piece of mind to me.
So I will have 60A breaker at main panel feeding a 50A 240V breaker and a 10A 110V breaker in garage.
I have breaker in subpanel naturally, but there is nothing between the outlet in garage and the subpanel inside my home. That is, no breaker or secondary subpanel in the detached garage. (There is a main breaker for the feeder to the home that is accessible near the meter/main panel which is outside.)
@DouglasR, my runs where exactly the same and the bill too! I used SolarCity. My other estimate with another contractor was upwards of $5000 (which included a lot more trenching and was a totally different approach).
I had an experience with Solar City that was not as good. See my post here: http://www.teslamotors.com/forum/forums/any-experience-solar-city-electric-charging-installation-0
Yes! Charging runs perfect. at 40 amp,no heat; if I plug in when I'm home its always fully charged( i charge to 80 %- 184 miles,60 kw battery). Call Brady-on a time/material basis appears cheaper than RA paid doing it himself although I had a shorter run
Almost all of the material cost was the #6 wire, about $212. Each wire was selling for $1.32 per foot, times 4 = $5.28 per foot, so distance makes a big difference. Total time to install is probably only 3 hours tops, less for an electrician that does it all of the time. Only took 1.5 hours to install the conduit and boxes, should take me only another 1 to 1.5 hours to complete. I'm slow.
In the event I couldn't access my garage to disconnect, I could still access the main breaker on the main service panel outside. Installation passed without any issues (only comment was that the electrician should have had the inspection done before they filled the trench with dirt, as he had to take my word for it that conduit was 12" under ground and joints were sealed etc.).
Now all I need is the car!

The outlet was a good 30' from the panel, so he charged me just over $700. I could have probably gotten this done cheaper, but it wouldn't have been worth the hassle of multiple bids. Brady did a good, clean job and was able to do the future-proof install easily.
I see that there is the sales tax exemption for the install of charging outlets at home that few of you have claimed , can someone pl. post the link or the exact form # to fill ?
