If the busway is not installedimmediately, it should be stored in aclean, dry location. Factory suppliedrecord drawings as well as installationtools should be accessible in preparationfor installation.UL 1479 Fire Rated InstallationsSentron Busway has been tested inaccordance with UL 1479 and offers acertified two hour fire rating for gypsumwallboard construction and a three hourfire rating for concrete slab or blockpenetrations. These ratings wereachieved using standard buswayinstalled with SpecSeal ® sealant fromSpecified Technologies Inc.

Sentron is the firstbusway system to achieve a fire ratingfor gypsum wallboard construction.MeasuringCritical to the success of any buswayinstallation is the layout and the accuratemeasuring of the busway. First andforemost:Select a route for your busway that willrequire the fewest fittings and themaxumum number of 10' (3.05m) sections.It is important that the busway system bedesigned to meet the requirements of theNational Electric Code for Busway. Thereare a number of techniques that may beused to ensure an accurate measurementbefore purchasing and installing thebusway. The following tools will berequired during layout and masuring:▪ 100' (30.48m) tape measure▪ Meauring Stick▪ Chalkline▪ Plumb Bob▪ Marker(A laser distance measuring device maybe used to speed the measuringprocess).1. _____ Drawing Attached (Required)2. _____ Estimate Sheets Attached (Required)3. _____ Dimensions from walls, column lines, etc.4. _____ Wall, floor, roof thickness and pitch5. _____ Floor Elevations_____ Floor to floor_____ Floor to ceiling6. _____ Wall Locations7. _____ Equipment Pads shown: Height _______8. ____ Existing busway to be extendeda) _____ Phasingb) _____ Nameplate Informatioc) _____ Match to competitor: Call the factory9. ____ Secial Switchboard Connection: Provide Details10. ____ Phase transpositions: Provide phasing on drawing.FlatwiseEdgewiseB) Specifications(Check or fill appropriate blanks)1. _____ Standard busway meets specifications2. _____ Exception to specificationsa) Short circuit withstand _____ Ampere Symmetricalb) Voltage Drop Requirement _____c) Temperature-rise requirement _____d) Current density requirement _____e) Special Paint: Provide paint chip _____f) Other: ____________________________Exception to electrical specifications: Call the factory.Other Notes: _________________________________________________________________________________________________________________________________Minimal ClearancesMinimum clearances for installing feederbusway are shown.
