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 monoxide poisoning 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.
Shipment: Unpacking 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.
Secure with 3/8” fasteners
Figure 1-Bottom View

SERIES 300 Quick Connect Power Panel Installation Manual

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 t he
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)
Place rotation label here
Figure 4

SERIES 300 Quick Connect Power Panel Installation Manual
6 381333-476 A
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
installation
1. Do not attempt to use the ASCO SERIES 300 Quick Connect
