Installed my Clipper Creek HCS-40. Great quality unit, feels very heavy duty. It is a bit larger than I imagined from online photographs, but nicely sized and 25 foot cord is great. Excellent unit for the price.
Charging started right away, it has a loud positive sounding relay which makes it pretty easy to tell when it starts, but also has the light on the unit and of course the horn chirp from the Volt.
I love this because it will allow me to charge outside my garage (working on a project and need my Volt outside) with the long cord, and the cord is also very high quality and flexible even in cold weather.
Glad I bought this unit, will update with how well it works for me in the future after I have had some time with it. Nice to be able to charge rapidly over lunch, especially in the winter when my range is limited.
The HCS-40 is overkill for the Volt, but my next vehicles will all be plug-in so I am expecting to get use from it in 3 years with a Bolt or Tesla 3 or whatever else happens to come out.
125' 8-2 NM-B wire: $100 (Used only 40 feet or so, but 125 foot spool was cheaper than 75 foot spool)
40 Amp breaker: $10 (or less)
Junction Box, 3/4" staples, 8 gauge wire nuts, 3/4" cutout clamp for back of box: $10 (or less)
HCS-40: $616.73 (incl. ship.)
Total: about $736 + electrician. I will sell the left-over wire that I have and recoup maybe $60 of it.
