Sources that produce [[direct current]], such as [[Photovoltaic module|solar panel]]s, must be coupled with an [[Inverter (electrical)|electrical inverter]] to convert the output to [[alternating current]] for use with conventional appliances. The phase of the outgoing power must be synchronized with the grid, and a mechanism must be included to disconnect the feed in the event of grid failure. This is for safety{{spaced ndash}} for example, workers repairing downed power lines must be protected from "downstream" sources, in addition to being disconnected from the main "upstream" distribution grid. Although a small generator lacks the power to energize a loaded line, this can happen if the line is isolated from other loads. [[Solar inverter]]s are designed for safety{{spaced ndash}} while one inverter could not energize a line, a thousand might. In addition, electrical workers are trained to treat every line as though it was live, even when they know it should be safe.<ref>{{cite web|url=http://www.statefundca.com/safety/safetymeeting/SafetyMeetingArticle.aspx?ArticleID=23 |title=Know the Ground Rules for Electrical Safety |publisher=State Compensation Insurance Fund, California |access-date=2013-12-15 |archive-url=https://web.archive.org/web/20130617230951/http://statefundca.com/safety/safetymeeting/SafetyMeetingArticle.aspx?ArticleID=23 |archive-date=2013-06-17 |url-status=dead}}</ref><ref>{{cite web|url=http://www.safetyservicescompany.com/blog/electrical-safety-lineman-electrocuted-after-reportedly-violating-the-%E2%80%9Chot-gloves%E2%80%9D-rule|archive-url=https://web.archive.org/web/20110911180919/http://www.safetyservicescompany.com/blog/electrical-safety-lineman-electrocuted-after-reportedly-violating-the-%E2%80%9Chot-gloves%E2%80%9D-rule|url-status=dead|title=Electrical Safety: Lineman Electrocuted after Reportedly Violating the 'Hot Gloves' Rule|archive-date=September 11, 2011}}</ref>
