|  Scientists at DOE's Pacific Northwest National Laboratory developed the “freeze-thaw battery,” which freezes its energy for use later, is a step toward batteries that can be used for seasonal storage: saving energy in one season, such as the spring, and spending it in another, like autumn. The molten-salt battery can lock in energy for months without losing much storage capacity. |

Members Only |  Larger industrial and manufacturing facilities as well as campus-style facilities often distribute power at voltages up to 15,000V (15kV) within the facilities. No matter the voltage level, the basic electrical safety rules found in the NFPA 70E, Standard for Electrical Safety in the Workplace, still apply. Depending on the voltage level, the changes include certain shock boundary distances and the tools necessary to verify an electrically safe work condition. |

|  ABC hired a contract thermographer to conduct scans on panels and switchboards. The images and written report identified 62 potentially bad connections; all were addressed during the spring shutdown. ABC contacted your firm and one of your two Level II thermographers repeated those earlier scans and found 97 potentially bad connections, including 59 of the 62 identified in the previous scan. ABC has no confidence in the results and wants its money back. How should you proceed in resolving this? |

|  To the uninitiated, this topic sounds like a simple one. But turn to Article 400, and you see Table 400.4 that, with its extensive table notes, takes up five full pages plus a nearly full sixth one. Then you have Tables 400.5(A)(1), 400.5(A)(2), and 400.5(A)(3) after that. Spend a few more minutes looking at Article 400, not only the tables, to ensure everything is right. |
