Selection<\/span>\r\n\r\n  <p class=\"ly-intro\">\r\n    If an oil and gas control panel needs two power sources, an automatic transfer switch may form part of the backup-power architecture. But the first question is <strong>not the ATS current rating<\/strong>. The first question is where the equipment will be installed and whether that location is classified as a hazardous area.\r\n  <\/p>\r\n\r\n  <p>\r\n    This guide focuses on <strong>low-voltage automatic transfer switch selection for suitable non-hazardous control-panel and auxiliary distribution applications<\/strong>.
