They are nuts. This is not a huge big deal, but my electrician called ESA to verify that separate disconnecting means are not necessary, since the NEMA 14-50 provides that function. Unfortunately, they told him that the switch is necessary. The stated reason: in case the user doesn't unplug the car first. Something tells me that if some idiot doesn't think to unplug the car first, they're not going to think to pull the switch first either. DUH!!! What we need now is disconnecting means for the disconnecting means. No wait, what if someone is working on the new disconnecting means. Better add another one! Switches all the way back to the panel!
