What ratings / MOS /job codes work with Uninterruptible Power Supply (UPS)?

<p>There is huge need for technicians with UPS experience in the civilian job market. Who uses, installs, maintains, and troubleshoots the equipment. </p><p>&nbsp;</p><p>An <b>uninterruptible power supply</b>, also <b>uninterruptible power source</b>, <b>UPS</b> or <b>battery/flywheel backup</b>, is an electrical apparatus that provides emergency power to a load when the input power source, typically <a title="Mains electricity" href="http://en.wikipedia.org/wiki/Mains_electricity"><u><font color="#0066cc">mains power</font></u></a>, fails. A UPS differs from an auxiliary or <a title="Emergency power system" href="http://en.wikipedia.org/wiki/Emergency_power_system"><u><font color="#0066cc">emergency power system</font></u></a> or <a title="Standby generator" href="http://en.wikipedia.org/wiki/Standby_generator"><u><font color="#0066cc">standby generator</font></u></a> in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries or a flywheel. The on-battery runtime of most uninterruptible power sources is relatively short (only a few minutes) but sufficient to start a standby power source or properly shut down the protected equipment.</p>
