Electrical Load Calculations - Do you perform these?

[tinadelllic]

For those of you that perform electrical load calculations or panel schedules for the electrical service on your projects, what resources have been helpful to you? Have you created any templates or worksheets for yourself to make this an easier process? Would you be interested in having a template in chief architect that another user has made?

 

I'm curious who would be interested in sharing tips/tricks or anything that could be shared to used in chief architect. I have some things I've developed for my own use but not sure if others would find this useful or how many users incorporate this into their plans and services.

 

Here's a few links I found really helpful:

Wow......I would utterly fail.  

I was a framer for a couple decades and do not have professional electrician experience.  

In those cases, since I work mostly for builders, they hand off the plan to their electrical sub and they do those aspects under their master electrician license.

 

Just imagining how I'd mess that up is sad and comical in my head.

If you use a combination of polylines for hips, that report to a custom schedule, as well as outlets, in conjunction with custom fields in your OIP, you can make an auto generated panel schedule and could even do load calcs using macro

This may be useful for load calcs.

Thanks for the input but you're speaking martian to me  Let me know if you want to collaborate on creating something new for this.. I think other calculations like attic ventilation, crawlspace ventilation, natural ventilation and glazing calcs could be simplified with a step by step table in chief if load calculations could be.

Here's what I use to check electrical load calcs that are submitted to my municipal building department.
