Needed to disconnect the line voltage feeding a chiller to make a repair. After the repair was complete I worked with the on-site electrician to get the machine powered up. I noticed the button, circled in yellow, was pushed in. The other breakers in the room the button was retracted. It looks to be some type of locking mechanism to remove the breaker. The electrician was unsure of what this button was and how to retract it. We removed our lockouts and he closed the circuit. I verified line voltage at the chiller and was able to get it online. I'm just curious if this should be of concern or addressed by another electrical contractor. The electrician I was working with working didn't seem concerned, but it isn't reassurance he didn't know what it was. The chiller did run with the button pushed in. My concern is the breaker may become physically disconnected and cause potential chiller/electrical damage. I apologize for my ignorance on the topic, just trying to educate myself as I was unable to while on-site with an electrician. Thank you.
