Is it possible that some T5 lighting fixtures are perfectly efficient? One might get that idea based on some efficiency ratings of 98–100 percent, although it might not seem possible. Such a rating must be a mistake, right? But it’s not.
The Occupational Safety and Health Administration (OSHA) prides itself in the fact that, since the enactment of the Occupational Safety and Health Act of 1970, job-related casualties and injuries have been reduced by more than 60 percent.
From talking to electrical contractors lately, I know it’s still tough to get profitable work in the current economy. However, I also find most of the contractors who have prepared well for such a poor economic situation are maintaining a substantial workload.
The Occupational Safety and Health Administration (OSHA) is in the final stages of updating the existing standard on electric power generation transmission and distribution (1910.269 and Subpart V) related to electrical protective equipment.
The 2014 National Electrical Code (NEC) development process is in full swing with the NEC technical committees acting on 3,745 proposed new articles and revisions. New and improving technologies and industry advances are driving changes into the electrical industry at an accelerated pace.
Intelligent visual surveillance systems monitor persistent and transient objects within specific environments in real time. The primary intentions for systems are to provide an automatic interpretation of scenes and to understand and predict the actions and interactions of the observed objects.
The role of an estimator has evolved, yet it remains rooted in the principles that defined it. A 41-year estimating veteran helps illustrate the means by which estimating has shifted and how the measure of the estimator’s skills plays a key role.

You may already work with building information modeling (BIM). Perhaps you’ve built a team proficient in this technology or hope to in the near future. At the very least, you suspect one day a project will come your way that will require BIM.
With the economy still reeling from the effects of recession, unemployment, and wavering business and consumer confidence, electrical contractors (ECs) are re-evaluating their businesses and taking on new and different roles and business models in an effort to remain competitive.
I often get calls from professional contractors who have become involved in design/build electrical projects that include the design and installation of fire alarm systems. The reasons for the calls vary, but most are born of surprise and frustration.
