<p>On the wall opposite the electrical switchgear cage is this sheet of
paper discussing the proper maintenance and safety requirements of a
large 144-volt array of lead-acid batteries that evidently was once
present. I really wonder what the paper mill would have used 144 volts
of battery provided DC power for. C. Demaine says that the 144 volt
battery array most likely powered the mill's electrical control switchgear,
which often runs on 120VDC. And, when the mill is completely blacked
out, he notes that some power is needed to get the switchgear working
in order to start things up.</p>

<p>There are some light-duty switches and fuse boxes on the outside wall
here.</p>

<p>And an exit door that now exits to a rather thickly wooded area adjacent
to somebody's house.</p></td>

<p>Inside the cage, there are some large switches whose function appears to
be to switch an entire mill building between Powerhouse-generated power and
grid power:</p>
<p><a href="/photo/pwr/1024/IMG_2906.jpg"><img src="photo/pwr/IMG_2906.jpg" width="400" height="300" border="2"></a></p>
<p><a href="/photo/pwr/1024/IMG_2907.jpg"><img src="photo/pwr/IMG_2907.jpg" width="400" height="300" border="2"></a></p>
<p><a href="/photo/pwr/1024/IMG_2908.jpg"><img src="photo/pwr/IMG_2908.jpg" width="400" height="300" border="2"></a></p>
<p>Or perhaps they switched individual (large) pieces of factory equipment
rather than entire buildings...</p>
<p> </p>
<p><a href="/photo/pwr/1024/IMG_2909.jpg"><img src="photo/pwr/IMG_2909.jpg" width="400" height="300" border="2"></a></p>
<p>Adjacent to the cage, there are some cabinets with interesting electrical
connectors on top.</p>
<p> </p>
<p><a href="/photo/pwr/1024/IMG_2914.jpg"><img src="photo/pwr/IMG_2914.jpg" width="400" height="300" border="2"></a></p>
<p>There is a small supply/maintenance area near the electrical equipment,
as well.</p>
<p> </p>
<p><a href="/photo/pwr/1024/IMG_2918.jpg"><img src="photo/pwr/IMG_2918.jpg" width="400" height="300" border="2"></a></p>
<p>There are steam pipes in the area too, which makes sense, since we are still
underneath the turbine room.</p>
