I was working for a company that had bought an old manufacturing plant and converted it to a warehouse. The power factor was all fucked up. The engineer from the utility company came out and told the company that they were going to have to replace the transformers because they weren't using enough power to correct the problem.
Boss came to me and told me it was going to cost a ridiculous number. I said fuck that and I designed and built a capacitor bank. I have had several interactions with electrical engineers that have made me question their education.
I'm an idiot, but come on. If an electrical engineer is going to be designing systems for construction, they cant just put a little note telling me that the system must follow the NEC, and not know dick about the NEC. I will rail their ass on the change order.
