I've seen the Wall Connector referred to with different names. Tesla even has different installation instructions for what they call the Wall Connector and the High Performance Wall Connector: http://www.teslamotors.com/sites/default/files/downloads/charging_wall_connector.pdf https://www.teslamotors.com/sites/default/files/blog_attachments/hpwc_install_guide_rev_3.pdf Are they the same thing? Am I missing something? Is there a reason for the different names? Thanks and please forgive my complete noob question.
