<DIV><FONT size=2 face=Arial>I am in need of hands-on advanced training for my
own continuing education. I have a California C46 solar contractor's license and
plenty of experience designing and installing systems. But, as you all know,
there are always more details to master, code issues to be clarified,
and new technologies coming down the pike. I'd like to focus on off-grid
and on-grid w/BB systems over straight grid-tie.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I'm looking at Solar Living Institute as that's
here in NorCal, where I live.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Are there any training schools/programs that you
guys would recommend? </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>My main requirements are that the instructor
has 20+ years of hands-on experience and that the training is hands-on and fully
comprehensive. I am interested in getting NABCEP certified but I'm more
concerned with getting professional, in-depth training than with qualifying for
NABCEP exam requirements.</FONT></DIV>

<P class=MsoNormal>Here's a tough one for me to understand. I am installing 2
volt AGM batteries. There are two terminals for each battery polarity. I
have some height limits so I need to use the minimum wire size. Here's my
question: If I combine two identical conductors, what is the equivalent single
conductor size? <o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p> </o:p></P></DIV>
<DIV>
<P class=MsoNormal>I found one "rule of thumb" that says doubling like
conductors creates a AWG decrease of 3. Example: two #2 will be equivalent to
2/0. Is this true?<o:p></o:p></P></DIV>
