<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Arial","sans-serif"">About two months ago I inquired of this forum about complications that might result from running a residence on a 208 volt 3 phase system.  One respondent indicated that motors might be affected.  Sure enough the owner is having problems with the well pump.  It is tripping circuit breakers.<u></u><u></u></span></p>
