PRODUCT OVERVIEW
Application
EPI NEMA Type 3R Padmounted Bussed Secondary Enclosures or Tapboxes are designed to allow the distribution of large amounts of low voltage power. Ampacity ranges from 400 to 5000 amperes at 600 volts and below, single or three phases. Custom sizes and amperages are available.
Construction
Made from 12-gauge steel. A drip shield top and smooth seam-free sides, front and back prevent rain, snow, or sleet from entering the enclosure. Double doors with continuous stainless steel hinges are operated by a three-point latching mechanism with a handle equipped with padlocking provisions. The continuous stainless steel hinge has a stainless steel pin. All Buss Tapboxes include pentahead bolts on top and bottom of the door. Flanged bottom opening for pad mounting and conductor access.
Buss Bars
C110 Silver Plated Copper is used and bus bars are sized according to one square inch of copper bus per 1000 amperes. Buss bars are insulated with 3” hi 600-volt standoff insulators. Bars are punched with 9/16“ holes at 13⁄4“ each way to accommodate lugs.
Finish
The standard finish is Sherwin Williams ANSI-70, light-dove gray inside and out.
