Square D® I-Line™ electrical busway offers a complete line of compatible, sandwich-type feeder and plug-in busway lengths and fittings. It allows maximum flexibility, ease of installation, and offers electrical efficiency in the distribution of low voltage power for both commercial and industrial applications.

The broad range of I-Line busway products include:

I-Line Plug-In style from 225 A to 600 A with aluminum or copper conductors
I-Line II Plug-In and Feeder styles from 800 A to 4000 A with aluminum conductors, and to 5000 A with copper conductors.
Optional IP54 rated I-Line II offers dust and splash resistance protection in Plug-In and Feeder Styles

I-Line and I-Line II busways are constructed in three-pole and four-pole full neutral configurations for system voltages to 600 volts and are rated to allow 100% of the current to flow continuously.

The compact, totally enclosed design is lightweight and easy to handle. Labor studies have shown that a 75% savings in installation time is not uncommon when comparing I-Line busway with cable and conduit installations. This significant reduction in installation time can result in total installed cost for busway being significantly lower than other distribution methods.
