Hi
I am looking for a good book which describes how to design control circuits. For example I have a 125 VDC circuit with one contact in series with a solenoid valve. The solenoid valve is 35 watts which means in draws .28 amps in a 125 VDC circuit. The inductive break of my contact is 1 amp...
Hi,
I am working on a project to add a 480V delta feeder panel to an existing 480V delta main panel at an industrial type warehouse. The main panel (mlo) is being fed by three single phase 167KVA transfomers which means that they are rated to supply 602 amps total. I know the current setup is...
Hi All,
I was wondering if anyone knew of any books/websites/whitepapers/etc. which can direct me on making an informed recommendation to repair or replace large voltage AC squirrel-cage induction motors. What I am particularly interested in are approximate cost estimates for replacing...
Please help. I am a new engineer which explains the simple question. When purchasing a distribution panel to be fed by 480V delta 3 phase 3 wire is it okay to buy one rated for 480V wye 3 phase 4 wire? Are they always interchangeable? What differences would I have to look out for?
Thanks,
