SECTION 1 INSTALLATION

ASCO Series 300 Automatic Transfer Switches (ATSs) are Listed under Underwriters Laboratories UL 1008 Standard for Safety for Automatic Transfer Switches. All control features are UL Component Recognized, which assures that ASCO automatic transfer switches meet OSHA Safety Requirements and will be acceptable to electrical inspectors.

ASCO Series 300 Automatic Transfer Switches are suitable for emergency and standby system applications. They meet emergency system rating requirements as defined in National Electrical Code (NEC) Article 700 and UL 1008. Also, they are suitable for the requirements of NEC Article 517 – Health Care Facilities, NEC Article 701 – Legally Required Standby Systems, NEC Article 702 – Optional Standby Systems, NFPA 99 Health Care Facilities, and NFPA 110 Emergency and Standby Power Systems.

Rating Label

Each automatic transfer switch contains a rating label to define the loads and fault circuit withstand / closing ratings. Refer to the label on the transfer switch for specific values.

!

Do not exceed the values on the rating label. Exceeding the rating can cause personal injury or serious equipment damage.

Series 300 Automatic Transfer Switches are factory wired and tested. Installation requires skid removal then secur- ing the enclosure to the supporting foundation.

Remove the Shipping Skid

Open the front door and remove the four lag screws (two in front, two in rear) securing the enclosure to the wood skid.

Supporting Foundation

The supporting foundation for the enclosure must be level and straight. Refer to the applicable enclosure outline drawing included with the Series 300 for all mounting details including door opening space.

If bottom cable entry is used, the foundation must be prepared so that the conduit stubs are located correctly. Refer to the enclosure outline drawing for specified area and location. Provide cable bending space and clearance to live metal parts. 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 applicable enclosure outline drawing fur- nished with this switch and mount the Series 300 according to details and instructions shown on diagram.

Auxiliary Cable Box for 1000–2000 amp

An auxiliary cable box is required if the power cables do not enter the enclosure directly adjacent to the terminal lugs (for example, if all power cables enter the top or bottom). Order ASCO part no. 609027 if needed.

!

Do not route the power cables along

the sides of the Transfer Switch.

Line Connections

Refer to the Wiring Diagram provided with your Series 300 ATS. All wiring must be made in accordance with the National Electrical Code and local codes.

It is unnecessary to remove pole covers from the transfer switch. If you do remove them, reinstall them carefully.

De–energize the conductors before making any line or auxiliary circuitry connections. Be sure that Normal and Emergency line connections are in proper phase rotation. Place engine gen- erator starting control in the OFF position. Make sure engine generator is not in operation.

Testing Power Conductors

Do not connect the power conductors to the ASCO Series 300 transfer switch 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.

!

Protect the automatic transfer switch from construction grit and metal chips to prevent malfunction or shortened life of the ATS.

Connecting Power Conductors

After the power cables have been tested, connect them to the appropriate terminal lugs on the transfer switch as shown on the wiring diagram provided with this Series 300. Make sure the lugs provided are suitable for use with the cables being installed. Standard terminal lugs are solder- less screw type and will accept the wire sizes listed on the drawings provided with the Series 300. Be careful when stripping insulation from the cables; avoid nicking or ringing the conductor. Remove surface oxides from cables by cleaning with a wire brush. When aluminum cable is used, apply joint compound to conductors. Tighten cable lugs to the torque specified on rating label.
