I am a proud owner of a 2 week old Chevy Volt. I decided to purchase the 240 Voltec charging station from SPX. I have received it with a thinking I would have someone install it. I got nervous. I figured will my electrician really know what they are doing, the permits, the guarantee...uggg...So I called SPX and I have decided to install through them. Good or bad the total will be around $1,700.... Now...I currently have a 20amp circuit in the garage ready to go but the electrician who did the site assessment recommended I upgrade to a 40 amp. More wiring is required. I was quoted 2 prices. One with the 20 amp and the other with the 40 amp. It is a difference of $300.
Is going to the 40 amp the better option? I don't know much about electricity but I get all charged up reading this website. (pun here. ) Any thoughts? Stick with 20 or go with the 40?
