PowerCalc™ won Gold in Consulting-Specifying Engineer’s annual contest for Product of the Year 2016.      

Our February 8th newsletter discussed the 7 reasons for winning: the power of (1) the PowerCalc algorithm, (2) the PowerCalc panel, (3) the PowerCalc process, (4) PowerCalc for NEC compliance, (5) the PowerCalc Wizard, (6) PowerCalc in the cloud, and (7) the PowerCalc experience.    

Let’s discuss Reason #4 in more detail: PowerCalc for NEC compliance.    

Database, Database, Database - No BlanksSubscribe to our BLOG!

PowerCalc is smart with a proprietary database. The NEC’s 14 lookup tables in Chapter 9 and endless tables throughout its 1500+ pages are fully integrated into PowerCalc’s 7 million+ equations. Just 3 inputs per circuit (load kVA, type of load and #of poles) results in over 300 NEC compliant outputs. These outputs are also compliant with IEEE Standards 141, 399 as well as other applicable codes, engineering standards and NEMA Requirements.

Other software programs provide a blank database form for the User to complete the values, but not PowerCalc. Our database is fully populated and fully vetted …used to design hundreds of actually constructed projects.

“PowerCalc makes it  easy to be right and  difficult to be wrong.”  PowerCalc’s outputs are based on the minimum values required by the NEC and other standards. These values can be manually adjusted by the User, with the added protection of warnings flashing on the screen for errors.

Connected and Integrated

PowerCalc’s database and design allows for instantaneous changes. So, you know that piece of equipment added at the end of the project…no problem. Need to delete that wing of the hospital…also no problem. PowerCalc updates for changes instantly, seamlessly without any late nights and long weekends to get the project out the door.

Why is all of this important?

savetimesavemoney no logo (002).jpgPowerCalc automates the electrical design process.

It is well established that automation is the driver in our techcentric society and business world.

Automation drives productivity across all businesses large or small. Changes, even small ones, over time snowball into massive gains in productivity.

It includes: automation of processes with databases, standards, and updated procedures resulting in fewer errors, fewer building department comments and fewer issues with finished designs. And, just less time spent on design and repetitive calculations.

To illustrate this point, we’ve put together the chart shown that focuses on design time. It shows how PowerCalc streamlines the design process to save days of engineering man hours. Save Time/Save Money

Let me know what you think…and in our next issue we’ll talk about the power of the PowerCalc Wizard. Also, be sure to sign up for our blog.
