HDT’s Utility Distribution Boxes (UDBs) provide safe power distribution in applications requiring feed-thru to larger areas. In each model, the three-phase power is broken into three 120 volt circuits within the box. Other model features include the ability to read the single-phase load at each receptacle and ensuring that single-phase loads are equally balanced across the three phases from the power supply.

HDT offers three UDBs:
