3. INSTALLATION
WARNING!
There are many steps to follow in this
guide, if you miss or proceed too quickly
past one you may ruin your instal. We
recommend you read through this entire
manual and understand the process
before proceeding step-by-step.
STEP 1 - PLAN YOUR INSTALLATION
1. Before starting, we recommended checking with
your local building inspector to see if a permit is
19 in

required for this installation. Be sure to point out
that this kit will NOT be connected to your home
electrical wiring.
2. Inside, nd a convenient place for the power panel
a recommended 19 inches (48cm) from the oor.
The location should be between wall studs so the
conduit will pass freely through your wall, not in
line with an electrical outlet, and not in alignment
with known water, waste, or other pipes. Think
about the devices you want to power with this kit
and if they can be used in this area. Once you have
determined a location, mark the spot with a pencil.
This mark will be the center of the power panel.
3. Outside, estimate the spot on your exterior wall
directly opposite the location of the indoor power
panel. Make sure it is at, vertical, and clear of
objects such as bushes, utilities, cable TV boxes,
or other. Make sure that the area surrounding the
exterior wall is clear of obstructions so the power
cord from your generator can protrude out and
down from the inlet box. You need easy access
to this area day and night, during all weather, and
when the power is out. Your generator needs a
clear area it can be placed at least 10-ft away,
downhill from your house, where it can be reached
by your power cord.
NOTE
If you do not have a suitable location to instal
the outdoor inlet box opposite the indoor power
panel you may choose to instal the inlet box
in a remote location. It is possible to connect
the indoor power panel to the outdoor inlet
box using grounded building wire up to 100-ft

in length. You will need to install a recessed
junction box in the wall behind the power panel
to safely extend the wiring. You must consult
a professional electrician to complete this
alternate instal according to local
building codes.
STEP 2 - MAKE A HOLE IN YOUR WALL
NOTE
The 12-inch at drill bit supplied with this kit is
designed to drill through drywall, wood
paneling, plywood, wood studs, insulation
panels, wood, vinyl, aluminum, plank, and all
other non-masonry materials. If you need to drill
through masonry materials such as brick,
concrete block, or poured cement, we
recommend you purchase a 1 ¼-inch (32mm)
masonry drill bit or other drill bit suited for the
type of wall you have. Other adjustments in the
hole-boring process may be needed in drilling
through other wall types, including lathe and
plaster. Otherwise, follow all installation steps
as outlined below.

1. If any friends or relatives are nearby they will be
helpful to have on hand for this installation, but
may require snacks.
2. On the inside wall, center the pointed tip of the 12-
inch at drill bit on your pencil mark, level the drill
parallel to the oor. Slowly and steadily apply rm
in length. You will need to install a recessed
junction box in the wall behind the power panel
to safely extend the wiring. You must consult
a professional electrician to complete this

building codes.
STEP 2 - MAKE A HOLE IN YOUR WALL
NOTE
The 12-inch at drill bit supplied with this kit is
designed to drill through drywall, wood
paneling, plywood, wood studs, insulation
panels, wood, vinyl, aluminum, plank, and all
other non-masonry materials. If you need to drill

pressure as you drill through only your rst layer of
drywall or paneling, stop before drilling further.
3. With your drill bit now past the rst layer of wall,
with the drill off, probe the interior of the wall for
any electrical, water, or waste pipes that could be
in your direct path through the wall. If you nd any
obstruction you must try again in another location.
If your way is clear, pull the drill bit back toward the
interior wall and level the drill again.
4. Continue drilling. If the drill contacts any insulation
move the drill forward slowly at high RPM to
make sure the bit has a chance to cut through the
insulation gradually without snagging. Forcing the
drill bit through the insulation quickly may cause it
to snag.
5. Once the drill bit contacts the outside wall, apply
steady pressure until just the tip of the bit breaks
through. Ask your helper to watch the outside wall
and signal when the tip of the bit emerges. Stop
the drill and slowly back the drill bit completely out
of the inside wall.
6. Move to the outside of the house, center the
pointed tip of the drill in the hole that was created.
Keeping your drill level and on high RPM, carefully
and slowly drill through the wall, varying the drill
speed as needed to avoid cosmetic damage until
you have a clean hole.

11
STEP 3 - PREPARE TO MOUNT THE POWER PANEL
1. From inside your house, slowly push the 12-inch
PVC conduit through the hole until it contacts
the exterior wall. Gently probe with the conduit

until you nd the exterior hole, then push conduit
through. The PVC conduit should be protruding a
few inches out from each side of the wall.
2. Straighten the wires attached to the back of the
6-outlet indoor panel. Push all wires through the
conduit, then push the rear protrusion on the back
of the power panel rmly over the conduit.
3. Hold the power panel tightly against the inside wall
with its rear protrusion inside the hole you made.
Outside, have someone mark the conduit visibly
with pen or pencil 1/8-inch (3mm) away from the
surface of the outside wall.
4. Inside, make sure the panel is level and parallel to
your oor, as you would like it to be permanently
mounted. Insert the four white-head 1 7/8-inch
(4.9 cm) mounting screws into each of the four
mounting holes on the power panel and push them
with your hand or screwdriver into your wall just
enough to leave a clear mark.
5. Pull the power panel and conduit out of the wall.
Fully separate the conduit from the power panel
and attached wires.

STEP 4 - CEMENT THE CONDUIT TO THE POWER
PANEL
1. Use a hacksaw or PVC cutter to cut the PVC
conduit at the pencil or pen mark.
2. Reinsert wires of the power panel halfway through
the conduit. Do not insert conduit into the power
panel yet.
3. Apply a thin coat of PVC cement all the way
around the conduit on the end closest to the power
panel, as well as inside the rear protrusion of the
power panel where the conduit will sit.
4. Push conduit into power panel rear protrusion,
twist a quarter turn, and hold rmly for 10 seconds
until bonded.

STEP 5 - MOUNT THE INSIDE POWER PANEL
1. Drill a ¼-inch hole at each of the 4 marks on your
wall, deep enough for each wall anchor to be fully
inserted.
2. Insert one wall anchor into each hole and tap in
lightly until ush with your wall.
3. Carefully push the power panel now bonded with
the conduit back through the hole in your wall and
position so the four holes in the power panel align
with the four wall anchors.
4. Insert the 4 white head screws through the power
panel and screw into the wall anchors with
screwdriver until snug against the wall, do not
overtighten.

STEP 6 - ATTACH THE CONDUIT FITTING TO THE
OUTDOOR INLET BOX
1. Remove the screw below the plastic inlet port on
the metal outdoor inlet box and lift the metal
faceplate up and out. Place the base of the inlet
box face down on a solid surface so that the back
of the box with three mounting holes is facing
upwards.
2. Locate the circular knockout hole on the back of
the inlet box, remove the knockout using a
knockout punch set or a drill.
3. Unscrew the tightening ring from the PVC conduit
tting, leaving the insulating ring on the tting.
4. From the back of the inlet box push the threaded

end of the conduit tting through the knockout
hole. Screw the tightening ring onto the conduit
tting from the inside of the power inlet box and
tighten using pliers.
STEP 7 - TRY A DRY FITTING
1. Thread the wires through the conduit tting into the
inlet box. Push conduit tting over the conduit
recessed in the hole in your wall.
2. The metal inlet box should be ush to the outside
wall. Depending on how tight the inlet box is to
your wall, t one or two foam weather insulating
rings over the conduit tting on the back of the
inlet box. When the inlet box is pressed up against
the outside wall, the foam insulating ring(s) should
compress to form a tight seal.
3. If satised, remove inlet box from wall and
unthread wires.
