  1. More on the Importance of Proper Torque Settings

    Following up on the emailing about the importance of using proper electrical device torque settings, a customer shared his experiences dealing with improperly torqued connections. We recently installed three new 480V electrical panels with Square D breakers to feed HVAC units for our raised floor. When load tested with our generators the following month, one of the breakers popped. Little...
  2. Electrical Device Torque Settings

    Electrical device manufacturers recommended torque settings that range from 12 to 90 inch pounds depending on the device type, when terminating conductors. Device torque settings can vary dramatically between manufacturers for the same device. As an example, for a CS8369 device one manufacturer recommends 25 to 30 pounds, while another recommends 45 to 54 pounds. That's a very broad range...

Instead of spending the capital or devoting resources to upgrade their infrastructure, they are seriously considering contracting with a retail data center to host their data. Your concerns when outsourcing data hosting are the same as when...
  4. Taking Advantage of Free Cooling

    First off free cooling isn't free it would better described as reduced cooling. My data centers were located in Minnesota so we were able to take advantage of the outside temperatures for a good part of the year. Two of our sites utilized CRAC units with compressors to cool raised floor space. We set our wet cooling towers to make...
