Jim ____________________Reply Separator____________________ Subject: Proper Protective Earth Ground Symbol Author: "Jackson; William" <[email protected]> List-Post: [email protected] Date: 01/14/00 4:59 PM Greetings all, I have a request for interpretation of requirement. Which symbol is correct for use on a chassis for protective earthing - the upside down tree or the circle upside down tree or the pitchfork?? (Note:- the ground on the back of the box is generally marked "GND" and is screw and locking washer configuration). What is the correct marking to satisfy a NRTL for a marking?
