I have a project where the facility has a 4000 Amp RL Siemens Switchgear lineup as part of a double ended substation. The gear is fed from a 2000KVA transformer and the available fault current is about 69kA at 208 volts. The 4000 Amp main is rated 85kAIC but some of the feeders are rated 30kA...
I have heard that when a stand-by generator is connected to a UPS, the generator should be rated at least 3 times the KVA rating of the UPS.
Does anyone know where this recommendation comes from?
I have a project with a 200 KVA UPS system which would require a minimum of 600KW worth of...

I have recently taken and passed the EE PE exam. I recommend you take a look at the EE reference book, 6th edition by Camera. The format of the test requires that you answer 40 multiple choice questions about all topics of electrical engineering in the morning session, then you can pick a depth...
We have had this problem as well. Check to see that your paper size is correct in the plot dialog box. On our setup there is a 24 x 36 (oversize) paper option. If you choose this paper size by mistake the paper will print out larger than the standard paper size. This may explain why you are...

Are you using an HP plotter? I had the same problem. The solution for me was to double click a file HPSETUP.EXE in the AutoCAD directory and select disable plot memory optimization.
