I-Line Installation, Special Features, and Services

I-Line busway can be provided in colors other than ANSI 49 gray for an additional fee. The special color requested should be specified by an ANSI color code at the time of order entry. With typically lengthened lead times for special color parts, it is imperative to provide this information as early as possible in the order process so delivery commitments can be met.

Some customers require a lower current density busway than our standard for rigorous duty in their installation. Schneider Electric has developed a range of busway for the most commonly requested current density of 1000 A per square inch for copper busway and 750 A per square inch for aluminum busway. If you require this current density for your installation, specify it, and we can meet your need. If you have requests for another specific current density, contact your local Schneider Electric representative.

Schneider Electric also offers an I-Line II plug-in busway specifically designed for installation in riser closets of high-rise buildings. This plug-in busway has a plug-in door on the front side that faces out into the room. The back of the busway, which faces the wall, is blanked off with a feeder bus side rail.

This design provides a plug-in busway ideally suited for riser cabinets and gives the customer only the necessary plug-in openings. The catalog number for this device is the same as our plug-in busway, except an R is substituted for the P. (Example: if the standard plug-in busway prefix is AP2512G, the riser busway prefix is AR2512G.)

Some indoor busway is subject to occasional water exposure, such as roof leaks or sprinklers. While this application does not require the full protection of outdoor busway, additional protection is needed for the indoor busway. The splash resistant feature is tested to the International IEC 60529 standard and is rated as IP54. This rating specifies protection from dust (“limited ingress permitted with no harmful deposits”) and water (“splashed from all directions with limited ingress permitted”).

This feature is available as an option with indoor plug-in and feeder busway. It is identified by the addition of “M54” at the end of the standard catalog number.

To properly allow for the impact of total harmonic distortion (THD), a busway solution must address both the current capacity of the neutral and the ability to dissipate the heat generated with the maximum anticipated load. The increased neutral currents will result in additional heating of all phase conductor bars, therefore de-rating of the busway is necessary.

With the Schneider Electric harmonic busway solutions, the neutral is sized to carry the full current of the expected harmonic load, while the increased cross section of the phase conductors dissipates the added heat generated within the busway.

There are two harmonic busway offers available:

• 15%<THD<35% rating (letter X in the catalog number)

• THD>35% rating (letter Y in the catalog number)

For example, if the standard busway prefix is AP2512G, the THD>35% harmonic busway prefix is APY2512G.

I-Line busway has been seismically qualified to meet the seismic provisions of
the International Building Code (IBC), California Building Code (CBC), and
ASCE/SEI 7 based on triaxial shake table testing following the code recognized test protocol ICC ES AC156. All qualification shake table testing was conducted by an independent test facility to verify compliance to an Ip = 1.5 by verifying post test equipment functionality as required by ASCE 7 for equipment that is part of a seismic designated system.

The shake table earthquake simulation subjected the busway test specimens to dynamic demands that can be more severe than the earthquake codes for most locations. A certificate of self certification is available on request from your local sales office and is based on site-specific, code-defined, seismic demand requirements for the installed location information supplied to Schneider Electric.

The qualified busway equipment must be installed, anchored, and restrained in accordance with Schneider Electric installation guidelines. For the purpose of seismic restraint design, the center of gravity is centrally located for all outside linear dimensions for each section or device (as listed along with their respective weights). Anchorage of equipment to the primary building structure is required to validate seismic certification of the equipment. The structural engineer or design engineer of record is responsible for design of the code compliant seismic restraint system for the building equipment. Schneider Electric is not responsible for the specification and performance of seismic restraint and anchorage systems.

Schneider Electric can provide full-site measuring and coordination of a busway installation. This service is ideal for large complicated projects requiring close coordination with other services. This service must be requested at the time of specification and order entry. Refer requests for this service to your local Schneider Electric representative.

Trained and qualified busway personnel are on call 24 hours a day to assist in your emergency busway needs. Call Schneider Electric at 1-888-778-2733.

The “Missing Link” program is designed specifically to help a customer correct last minute changes to a project using busway. Those changes could include an unplanned obstruction requiring the busway to be rerouted, incorrect measurement of the busway run, or the need to order additional pieces to supplement busway previously ordered. The program applies to the United States, Canada, and Mexico, and guarantees shipment of factory-built busway in five to seven working days, or Schneider Electric pays for the premium freight. For complete details of the program, contact Schneider Electric at 1-888-778-2733.
