Installation
ASCO SERIES 300 Quick Connect Power Panels (QCP) are factory assembled and tested. It is designed for exterior operation ONLY. Installation requires mounting, connecting power conductors and auxiliary control circuits (if required.).
Supporting Foundation
The supporting foundation for the enclosure must be level, straight and capable of supporting the weight of the cabinet as well as the cable attached to it.. Refer to the applicable enclosure outline drawing included with the power panel for all mounting details including door opening space. Refer to the enclosure outline drawing for specified area and location. Proper clearance in the front of the Quick Connect Power Panels must be 36 inches in order to open access door and attach externally connected cables. When a concrete floor is poured, use interlocking conduit spacer caps or a wood or metal template to maintain proper conduit alignment.
Mounting
Refer to the outline drawing furnished with this switch and mount the ASCO
SERIES 300 Quick Connect Power Panels (QCP) according to details and
instructions shown.
NOTE : To prevent carbon monoxide poisoning from improperly ventilated
generator emissions, the Power Panel must ONLY be mounted outdoors away from
any building openings or HVAC inlets.
Mount the ASCO SERIES 300 Quick Connect Power Panels (QCP) to a rigid
supporting structure. Level all mounting points by using flat washers behind
the mounting hole locations to avoid distortion of the switch.
Line Connections
Refer to the wiring diagram provided with quick connect panel. All wiring must be made in accordance with the National Electrical Code and local codes.
DANGER
| HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
- De–energize the conductors before making any line or auxiliary circuitry connections.
- Be sure that Source 1 and Source 2 line connections are in proper phase rotation.
- Place engine generator starting control in the OFF position.
- Make sure engine generator is not in operation.
Failure to follow these instructions will result in death or serious injury

Testing Power Conductors
Do not connect the power conductors to the power panel until they are tested. Installing power cables in conduit, cable troughs and ceiling-suspended hangers often requires considerable force. The pulling of cables can damage insulation and stretch or break the conductor’s strands. For this reason, after the cables are pulled into position, and before they are connected, they should be tested to verify that they are not defective or have been damaged during installation.
Connecting Power Conductors
After the power conductors have been tested, connect them to the appropriate terminals on the power panel as shown on the outline provided. Make sure the conductors being installed are suitable for use with the terminals provided on the breaker and in the power panel . Standard terminals are solderless, screw type and will accept the wire sizes and types listed on the drawings provided with the power panel . Be careful when stripping insulation from the cables; avoid nicking or ringing the conductor. Remove surface oxides from conductors by cleaning with a wire brush. When aluminum conductors are used, apply joint compound to them. Tighten terminals to the torque specified on the rating label. Quick Connect Input Power Panels (3QCN) are equipped with recessed male 16 series single pole connectors (inlets) only for connection to a temporary or portable generator. Quick Connect Output Power Panels (3QCU) are equipped with female single pole connectors (outlets) only for connection to a portable load bank.
