In your voltage drop calculations, since I believe "K" is a constant, you need to list the value of "K". Will "K" vary with power factor? In addition, to calculate the VD on, say, a #6 AWG or #4 AWG wire, you need to have a conversion chart handy to convert AWG to CM.

Dear Mike , I am confused ,my mothernlaw house is quite old,but currently has been in a electrical fire , She told me that it started at an outlet by the kitchen,well my wife Unclce said it started from a light fixture in the ceiling,by the way that is my new email address.I have done electrical work for 13 years started out in the Pine Ridge Job Corp in building maintenance ,well that was back in 1991 of August graduated in March of 1993,well anways thats how I got into the electrical field .Got out and did a maintenace job for a club ,but didn;t care for that much always been enthused about the electrical part of the building maintenance and been interested ever since,I am glad to be part of your web site and enjoy the news letters,but I take electrical to heart,I will be taking my Journeymans Electrical exam on the January 20th 2007,which I am real excited yes been studying the code book pretty hard,well any ways what I wanted to ask was what would cause the electrical fire from a light fixture?my theory is too much wattage for the light fixture itself,but if you could please reply,n if possible would reall like to talk personally on the phon for beter understanding, Thank you Phil Hobbs.

How about a 2560 x 1600 background for the 30" Dell Flat panel crowd?

what is required when an inspector is requesting load calculations for a panel on a residence?

Your background has: Centimeter = Inches x 2.54 Inch = 2.54 centimeters

I didn't look past that point.

Mike,

What is the signfigance of using the Pittsburgh skyline as a background? That's my hometown and it is a wonderful skyline. Just wondering....keep up the good work. Thank you.

Mike, I found the following Story interesting.

Hi Mike, Could you check your three phase neutral formula? I've been using one for years that differs significantly from yours. Thanks, Ed

Thanks for the wide screen resolution. It looks great! And the formulas will be very useful.

Hi Mike,

Thanks you very much for the new background. It is really very useful.

The text on the download of the formulas is hard to read, it is blurry and broken up.My Monitor is only 13\" if that makes a difference.

Mike I've got your new desktop but the formula print is way too small. Please help a non- I.T. guy out.

Thanks, Keith
