From: Subrahmanya Ramakrishnan Sent: Monday, February 11, 2008 2:26 PM To: Thomas G. Brown Subject: Grounding requirements Tom As you know there shall be no floating metallic part in the machine. Thus all structures/casings shall be grounded. At present, the plan is to provide a 4/0 insulated ground cable to the grounding pad that you will be providing for each structure. The pad can be the same conducting material as the structure - it is not necessary that it should be copper! Burndy lugs cat# Standard length barrel #YA-28-2LN - dimensions (1/2"holes 1-3/4" apart 1.02" wide) will be used to connect the 4/0 cable. The 4/0 cable is of typically about 1/2" diameter copper. We will finally be selecting the cable size required - for design purposes please provide the pad as above. Raki
