from the service to the house loads. The load is often only 120VAC which gives a
large voltage drop using only the #2 and #4 conductors. My thought was to
install an autotransformer at the load end so that the current runs through the
#2 conductors at 240VAC for much less voltage drop. Are there any issues I
should be looking at doing this? I\u2019m thinking that to balance the legs a 4kVA
autoformer would be adequate. The circuit is protected by 30A breakers both
ends.<span></span></p>
<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:107%;font-size:11pt;font-family:"Calibri",sans-serif">Second question is if I could reduce the voltage drop even
more by taking the #4 and paralleling it to one of the #2 conductors. This
would eliminate the neutral on the long run. I\u2019m thinking that the autoformer
could generate a new neutral for the load circuits. This is an older install so
the neutral is already grounded to earth at both ends, there is no ground wire
between the two such as would be required by code now. I know that code does
not allow paralleling conductors smaller than 1/0 but I will disregard that in
this case since it\u2019s my own system. <span></span></p>

like to sell, or if you want one yourself we can do a bulk buy. Let me know off
list.</p><p class="MsoNormal" style="margin:0in 0in 8pt;line-height:107%;font-size:11pt;font-family:"Calibri",sans-serif"><br></p><p class="MsoNormal" style="margin:0in 0in 8pt;line-height:107%;font-size:11pt;font-family:"Calibri",sans-serif">Thanks,</p><p class="MsoNormal" style="margin:0in 0in 8pt;line-height:107%;font-size:11pt;font-family:"Calibri",sans-serif">Brad Bassett</p><p class="MsoNormal" style="margin:0in 0in 8pt;line-height:107%;font-size:11pt;font-family:"Calibri",sans-serif">AEE Solar<br></p><p class="MsoNormal" style="margin:0in 0in 8pt;line-height:107%;font-size:11pt;font-family:"Calibri",sans-serif"><span></span></p>
