A Closer Look into the True Cost of Replacing Electrical Switchgear

During my switchgear modernization presentations all over the US, I am constantly reminded of the concerns customers face with their aging electrical infrastructure. For the most part, these center around safety, reliability and productivity:

  • Replacements parts are very hard (or impossible) to be found and priced as an aftermarket product
  • Plants are exposed to forced outages and loss of production due to poor equipment reliability
  • Employee safety is often in question due to slow opening...
