Subject: [RE-wrenches] Knockouts far from the backplane.<br>

Friends:<br>
<br>
<br>
<br>
I have noticed increasingly that inverters I have been using (Soul-Arc and<br>
Fortress Envy) have knockouts that are far in front of the backplane on<br>
which the inverter would be mounted.  Connecting conduit from these<br>
inverters into standard gutters, load centers and pull boxes is quite a<br>
hassle:  Offsets can eat up a lot of vertical space.  Pulling elbows (LBs)<br>
don?t really work in this situation.<br>
<br>
<br>
<br>
See diagram below:<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
One solutIon is to stack pull boxes or gutters, althouigh this eats up<br>
vertical space and increases the labor and parts count:<br>
<br>
<br>
<br>
How are the rest of you handling this backplane problem?<br>
<br>
<br>
<br>
Thanks in advance.<br>
