Hello all,
I've given myself a regular internet headache trying to understand the relative merits of spring vs star washers for use on an earth stud for protective earthing purposes. What is the conventional wisdom and justification? I know I can trust you folks to be above a simple "we've always done it this way" Can anyone point me towards any citable references or standards covering this subject? I promise I will write a blog post to pull the information together for future confused generations.
