Tool Specs: Appropriate rain tight conduit fittings and cord grips, hole saw, adjustable crescent wrench, wire strippers and
cutters.
Configurations Shown: The following installation steps are for a single string transition using cord grips for the home run
cables from the PV system. There are two ways to transition wiring from the QBox. The first is through the attic using the
QBox's pre-installed, conduit pass-through with the patented Elevated Water Seal Technology™ (steps 4-7). The alternative
method is to leave the QBox from the side (steps 8 & 9).
Holes for Cord Grips: Use the drill starter along
the perimeter of the box to guide your hole saw.
Hole size is specified by the cord grip or conduit
hub manufacturer. Clean off all burs.
Install Output Wires: Pull the transition wiring
into the QBox, label all wires appropriately, and
strip sheathing from the end of all wires per
instructions found in Section VI. Ensure each wire
has a minimum of 6" of lead inside the box.
Push Wires Into Box: Push wires down into the
box and away from edge. Lid should close freely
without wire interference. Failure to do so will
prevent proper rainproofing of the enclosure,
voiding the warranty and possibly leading to
a short. Secure the lid per step 12 in section IV.

1
Attach Cord Grips: Install the cord grips and
tighten them to the enclosure to make the
watertight connection. Ensure all wires are de-
energized.
Properly label the wires following
NEC guidelines.
4
Connect Wires: Install the supplied wire nuts to
achieve one of the approved wiring combinations
outlined in Section VI.
7
Holes for Conduit: Use the drill starter along
the perimeter of the box to guide your hole saw
specified by the conduit hub manufacturer.
Clean off all burs. Attach the conduit to the box.
2
Install PV Wires: Pull PV system wiring through
the cord grips and tighten the cord grips to seal
around the wires making a watertight connection.
Ensure each wire has a minimum of 6" of lead
inside the box per NEC requirements.
5
Install Grommet: Slide the grommet over the
wires and push it down into the conduit such that
it extends over the cut edge and locks into itself.
The grommet should extend over the top and be
secured to the conduit. It should not be loose.
8
Connect Wires: Pull min 6" of transition wiring
into the QBox, label all wires, and strip sheathing
from the end of all wires per instructions found
in Section VI. Follow steps 5 & 7.
