This will give you a good laugh. We get called out after hours to a plant and the life blood system for that plant is down.
The machine HAD been running...
I listen to the master electrician jabbering.
He recounts that when he found the breaker it was hooked to 3 machines
Electrician shows some initiative!
so being a good fellow he goes to the supply store and gets another breaker and splits the load up by moving the panel to it's own breaker.
So far so good...
When he flips the breaker on it trips at once.
Technical Term: Ooooops!
When he walked around to the panel there was smoke billowing out if it.
Big Ooooops!
He is saying that it must have been an old power supply that just gave it up.
Sounds reasonable.
After we get it all tested out and running again it's real late at night.
Miller Time!
So we go home to get some rest. About 3am I sit up in my bed and smack my forehead and say I know what happened!
Eureka!
Then I go back to sleep.
Zzzzzzzzz!!!
The next morning we go back down to the plant and trace the conduit to the panel. When we open the panel door the following warning in red is printed on inside.
WARNING DO NOT HOOK 120 TO RED PHASE
RED PHASE IS THE HIGH LEG!
To listen to this guy talk he knows everthing and did everything an electrician could do.
I've been a sparky for 20 years...
Guess he can't read...
