Where I worked state law required someone knowledgeable be there 24/7. It was facilities where the patients could not just walk out if things went bad wrong. On my shift due to my experience and training I had I worked it alone handling boiler operations plus HVAC plus electrical, plus plumbing issues, and handled any and all other emergencies from the building on fire to a patient or worker stuck in an elevator I had to get out. Then there was a retirement center added to that too which was a lower priority. I was also trained to haul explosives. No bragging just the facts. I've see a lot, done a lot, and learned from it.
Let me ask you something. You have a burnt up three phase six lead hook up motor six leads to it coming off two 45 amp control panels & the motor draws 90 amps. The building is getting hot because it's August. You have an equal HP motor, equal in total amperage and voltage, and RPM's that can mount up the same base but it's only a three wire hook up. Without help from anyone what would you do. This should be an easy one for you. You got to make it work. What do you have to do to get it to work? What is the main information you actually have to figure out first to do it? How do you obtain it and be sure you are right? You mess this up and a lot of money and precious time goes out the window.
Been there done that & I had it done and operational by the time the licensed contractor pulled up. My boss was still scratching his head wondering what to do about the burnt motor. Now stop jerking me around like I'm some know nothing flunky just because I'm not a licensed contractor. I'd handled more crisis in a month in my line of work than you likely in your career installing Al Gore Commodes.
Being Licensed dosen't mean Boo. I sw a licensed contractor wire in a chiller at a Worlds Fair and forgot to put tape on the kearneys for the chill water circ pump motor. Made a real nice half dollor sized hole in the peckerhead of the motor. It ran several months till it shorted. But hey what do I know I'm not licensed.
So, which one of us do the police call as the expert on natural gas issues, when their own building needs to be repaired?
