Ground (electricity)
Thank you for attempting to contribute to the Ground (electricity) article. However, your contributions, such as the one here use undefined abbreviations. Such abbreviations are often only used in one country, so may be inappropriate for an international publication like Wikipedia. Finally, signatures (created with tildes ~ ) are only used in talk pages, not articles. --Jc3s5h (talk) 16:35, 28 May 2009 (UTC)
