Hi,
New here - first post ... I've been watching the site for a while. I'm on the waiting list for a leaf, and I happen to be an electrician. I've been planning my install for a charging dock and observed with extreme curiosity the "Electrical Capacity Requirements" listed on page 50 of the install manual for the AV charging dock I found on this site. ( http://www.responsivespace.com/mjw/EVSE-RS%20User%20Guide.pdf )
All but one of the of the requirements make so sense and have no bearing on whether or not a charging dock could be installed.
According to page 50 of the manual the requirements state you must have:
-200amp service
-sufficient space/capacity
-not be older than 1990
- if the dwelling is copper wired.
point by point,
-to install the unit you must do a load calculation based on the actual premises it is being installed in, the ampacity of the service panel and what is being used in the household - your local inspector and the federal and state electrical code will be able to assist you, but a 200amp service isn't required by any shape or form to support a 12-27 amp draw from car charger. It's the overall load calculation that will determine if you can support a charger, not simply requiring a 200amp service. this requirement makes no sense in my case my 100amp service can easily support the charger.
-sufficient space is a given, and BTW is the only "requirement" that actually applies - this would be determined by the previously mentioned load calculation
-must not be older than 1990. Why? we hate back to the future and star wars episodes that didnt suck? seriously - does your house expire like a jug of milk if it was built before 1990?
- if the dwelling is copper wired. again, unrelated - aluminum wire is present in hundreds of thousands of homes in north america, and there is no issue with it. like anything - it must be inspected and properly maintained. Guess what - your main feeder to your house is aluminum, as are the transmission lines.
If this has already been discussed on the site, my apologies! I am looking for input on these apparent "irrational" rules someone (most likely an attorney?) created.
