Toronto Electricians and Electrical Contractors

Industrial UPSs represent a great way for electrical contractors to increase business from new and existing customers. It’s just a matter of understanding all the potential applications for UPSs in commercial and industrial settings – many of which may not be immediately obvious. In general, applications that are critical in a commercial or industrial building – and thus require UPS protection – fall into one of four categories: Business process continuity, meaning systems required to keep the business operating and prevent damage to equipment, such as machinery on a production line. Safety and security systems, including emergency lighting, security cameras, fire alarms and smoke extraction systems. Heating, ventilation and cooling (HVAC) systems that are required not only for employee and customer comfort, but also for business purposes – such as the protection of temperature sensitive equipment or products in a manufacturing plant. Data and smart business applications, in...

Congress Has a Chance to Finally End the NSA’s Mass Telephone Records Program Earlier this month, the New York Times published a major story reporting that the NSA has stopped using the authority to run its massive, ongoing surveillance of Americans’ telephone records. After years of fighting mass surveillance of telephone records, the story may make our jobs easier: NSA has consistently claimed this surveillance was critical to national security.

As we told Congress, it is long past time to end the telephone records program for good. Now, we’ve signed a letter to House Judiciary Committee leadership repeating th...

This is a common question we’ve heard enough times that we decided to test containment across a range of “leakiness” and came up with some practical guidance. You may have heard the term “percent leakage” as a means of assessing the effectiveness of a hot or cold aisle air containment solution. But what does this actually mean? How would you measure it or validate a particular claim in your own data center? Does this percent leakage spec correlate to your desired data center operating temperature range? You may be paying for a tighter tolerance than what is really needed. Or worse yet, paying for a “tight” solution that doesn’t perform in practice as it did in a test lab. From reading this blog, you’ll learn some practical metrics and practices you can take to ensure that your IT equipment stays cool and your energy bills low. What is “percent leakage”? I searched for containment-related documents that included the term % leakage and I found two loose definitions in that they weren...
