Prior to Installation: Site Preparation
Prepare installation site according to local codes.
The ASCO Series 300 Quick Connect Power Panels are to be
set on an exterior pad
and secured to a building or secured
to a pad using 3/8“ fasteners
(See Figure 1).
The surface where the ASCO Series 300 Quick Connect
Power Panel is to be secured must be capable of supporting
the weight of the cabinet as well as the cable attached to it.
The following should be taken into consideration when
locating the ASCO Series 300 Quick Connect Power Panel:
– The ASCO Series 300 Quick Connect Power Panel is
designed for exterior operation ONLY
– Identify and meet local codes and local Authority
Having Jurisdiction (AHJ)
– Toprevent carbon monoxidepoisoning from improperly
ventilated generator emissions, the Power Panelmust be
mounted outdoors only. The mounting location is to be
carefully selected to allow convenient connection to a
generator, and located a suitable distance away from any
building openings or HVAC inlets.
– Proper clearance must be allowed in front of the ASCO
Series 300 Quick Connect Power Panel to allow for
opening of access doors and attachment of externally
connected cables. This distance should be no less than
six (6) feet from the face of the panel.
– While lockprotectionis provided, access by unauthorized
personnel and vandals should be taken into consideration
when
locating this device.
S h i p m e n t : U n p a c k i n g and Inspection
Be careful in the use of sharp object when cutting
packaging
as damage to the outer enclosure
may result.
Perform a visual inspection to ensure the door and all hasps
are in
functioning condition and that the panel integrity is
intact
.

Initial Installation
ASCO Series 300 Quick Connect Power Panels are front
heavy (See Figure 2). Care must be taken to secure the
device when it is lifted and moved.
– Please note that the 2000 Amp versions weigh
approximately
2 20 pounds and the 2400-4000 Amp
versions range from 317-360 pounds for aluminum
enclosures. Stainless steel enclosures are approximately
200 pounds heavier at their respective amperage levels.
The installation of the ASCO Series 300 Quick
Connect Power Panel should be carried out by
qualified personnel in accordance with local
electrical codes.
The ASCO Series 300 Quick Connect Power Panel
must be installed in conjunction with a transfer
switch.
The transfer switch shall not have a rating greater
than the ASCO Series 300 Quick Connect Power
Panel.
Figure 2
Step 1: Fasten the ASCO Series 300 Quick
Connect Power Panel to secure base
1. Base must be level and plumb to allow for proper
drainage
from ASCO Series 300 Quick Connect Power
Panel weep holes
2.
Fastening onto an external wall using 3/8” fasteners
must be
completed prior to proceeding with any
terminations (See Figure 1 for hole spacing)
Step 2: Installing the Conduit
Conduit to enter through the bottom,rearand sides o f the
unit.
(See
Figure 3)
To maintain TYPE 3R Rating compliance for the
enclosure, proper sealing procedures must be
followed. This
is to include, but not limited to, the use of
proper gaskets.
1. Remove rear and side panels to expose termination
chamber
2. Conduit to be sized according to cabling rating
3. It is recommended that a knockout punch be used to cut
hole for conduit.
4. Place the punch on the panel that was removed from the
enclosure and draw the punch through to the die on the
outside.

Installation -Input Panels
This section is for Installation of Input Panels.
For Installation of Output Panels proceed to
Page 9.
Step 3: Wiring the Lug Terminals
Ensure circuit breakers are OFF and the transfer switch is
locked
out from utility power prior to connection.
Failure to install transfer switch will create the potential for
the
generator to energize utility lines and endanger utility
personnel.
Conversely, utility lines may energize the ASCO
Series 300 Quick Connect Power
Panel and endanger
generator personnel.
The ASCO Series 300 Quick Connect Power Panel
is for use only for
connection of a generator to the
source terminals of a
transfer switch, such that the
inlets are only energized from
the generator.
1. Pull the cables for the transfer switch to the ASCO
Series 300 Quick Connect Power Panel
2. Beginning with the ground, strip and install the cables
in the appropriate compression terminals
The terminals can accommodate #2 to 600MCM, Copper
wire only
3. Tighten terminal screws to 375 lb-in torque each
4.
If metallic conduit is used, connect ground wire from
ground bushing on conduit to the ground connection
point in the upper right quadrant of the panel
5.
Ground conductor must be a minimum of #2 AWG
Conduit shall NOT be relied upon to provide grounding
protection to tap box
6. Continue to connect the neutral and then the phases
7.
Vacuum entire upper chamber to ensure no metal
shavings are left behind
Three phase power systems consist of three phase or hot
conductors that are shifted by 120 degrees. Three phase
loads such as motors may only work properly if the phases
are
connected in the correct order. Some motors may work
when
connected improperly, but will operate backwards.
Utility power
and electrical generators may be wired either
in a clockwise or counter-clockwise order. It is important that
any generator
connected to the ASCO Series 300 Quick
Connect Power Panel is connected in the same rotation
(clockwise or counter-clockwise) as the utility power.
Step 4: Determine Phase Rotation
This information will be needed when connecting a
generator .
1. Determine phase rotation of the utility power.
2. Connect a phase rotation meter to a three phase power
source in the building and record whether the building is
wired clockwise or counter-clockwise
3. Apply the provided label to the inside of the ASCO
Series 300 Quick Connect Power Panel on the inside of the
cam connection chamber door . (Figure 4)
Figure 4
Place rotation label here

ASCO Series 300 Quick Connect Power Panel
6www.ascopower.com 381333-476
Step 5: Configuring the Phase Rotation
Monitor
A phase rotation monitor comes standard on all 2000A -4000A
pad mount Input panels. The Phase rotation monitor is
prewired from the factory for ABC rotation. (Figure 5)
1. Should the phase rotation monitor configuration and
utility power (label found on the inside of the door for the
Cam connection chamber) match, proceed to Step 6.
2. Should the phase rotation monitor configuration and
utility power (label found on the inside of
the door for the
Cam connection chamber) differ, swap the A and B
phase rotation connection wires at the camlock
connection so it matches utility power and is consistent
with the label found inside the door.

Step 7: Determining phase rotation of generator
1. Disconnect generator from all loads if needed
2. Connect a phase rotation meter to the output phases
of the generator
3. Record generator phase rotation (clockwise or
counter-clockwise)
Step 8: Conduct a safety test to ensure proper
