What is a Square D QED I-Line Switchboard?

Square D QED I-Line Switchboards provide a convenient and economical means of distributing electric power. These enclosed, free-standing structures contain circuit breaker or fusible overcurrent protection for services rated up to 5000 A with a maximum voltage of 600 Vac. QED I-Line switchboards are custom-made for use as service entrance equipment or as distribution centers in commercial, institutional, and industrial applications.

An auxiliary section is also available for cable or bus transition or to provide additional space for connecting the service conductors to the line side of the main. The auxiliary section is a full-height section with a depth to match that of the adjacent section. It can contain customer metering or through bus and incoming lug pads.

The QED I-Line frame allows various special components to be mounted in the switchboard. These components include automatic throwover systems, transfer switches, and special metering systems. This flexibility means the QED I-Line switchboard can meet customer requirements on the most complicated applications.

High-Quality LV Switchboards with Fast Turnarounds

Through Bus

Square D QED I-Line switchboard distribution sections are also available in individually mounted construction. This type of construction allows for larger feeder ampacities up to 4000 A. The individually mounted feeder devices can contain PowerPact M-, P-, and R-frame and Masterpact NW circuit breakers, or Bolt-Loc fusible switches to a maximum of 4000 A. Ground fault protection is available through Micrologic trip units on PowerPact M-, P-, and R-frame and Masterpact NW circuit breakers. Ground fault protection is available on Bolt-Loc switches with the Type GC ground fault system. Zone interlocking is available as an option between the feeders and main.

Bus ampacity ratings have been determined from UL 891 heat rise testing. This method is the most accurate, since actual tests are used for determining optimal bus sizes.

A 100% neutral bus is provided on 3-phase, 4-wire (3Ø4W) and 1-phase, 3-wire (1Ø3W) systems. Ground bus is standard and matches the type of through bus. Optional, increased-size ground bus is available.

“E” Connector Assembly

The “E” connector assembly eliminates the alignment problems associated with conventional bus bar connections. The “E” connector assembly, consisting of an “E” connector, carriage bolt, conical washer, and hex nut, requires only one wrench to tighten. This assembly is used on splice connections and connections to through bus from the panel bus. By providing more uniform pressure over the contact surface, a highly efficient and cooler connection is obtained.

Group-Mounted Distribution Sections

Square D QED I-Line Switchboard distribution sections are available with either an I-Line™ or QMB group-mounted distribution panel. Each of these interiors mounts to the frame front corner channels with horizontal mounting rails. Connectors secured to the through bus with the “E” connector assembly bring power into the center of each interior bus. The vertical bus feeds power to each branch disconnect. When a neutral is required, it is located at the side of the QMB vertical bus assembly or at the side of the I-Line circuit breaker mounting pan. This convenient neutral location provides for front accessible neutral connections. Ample wireway space is provided for the load side cabling of branch disconnects.

Large Feeders

Square D QED I-Line Switchboard distribution sections are also available in individually mounted construction. This type of construction allows for larger feeder ampacities up to 4000 A. The individually mounted feeder devices can contain PowerPact M-, P-, and R-frame and Masterpact NW circuit breakers, or Bolt-Loc fusible switches to a maximum of 4000 A. Ground fault protection is available through Micrologic trip units on PowerPact M-, P-, and R-frame and Masterpact NW circuit breakers. Ground fault protection is available on Bolt-Loc switches with the Type GC ground fault system. Zone interlocking is available as an option between the feeders and main.

Manufacturer’s Certification

As long as the seismic capacity of the equipment exceeds the site-specific demand, a certificate can be generated and issued. Schneider Electric ensures that code compliance verification is as simple as supplying the job site address. Our certificate clearly states the code requirement and our equipment capability.

This simplicity eliminates the need for the design professional to translate code criteria into an equipment requirement, and then sort out less-than-clear manufacturers’ test results to verify compliance to the site-specific code requirement of the project.

For sample certificate and compliance notes, see pages 54 and 55. Contact your local Schneider Electric representative to obtain a seismic certificate.
