Of course, the ground wire is still a separate connection. These are for the SB-300, SB-301, SB-400, SB-401.<br><br>The reason for a 3-wire cord is for safety and to eliminate the "tickle" that can often be on the chassis if the unit is not grounded.<br><br>Information at:<br><br>http://k9sth.com/uploads/Heathkit_Power_Cords-1.pdf<br><br>Glen, K9STH<br><br>Website: http://k9sth.com<br></td></tr></table><br>
