palmettoinspect Posted July 29, 2014 Report Share Posted July 29, 2014 Are these wire tabs around these breakers handle locks? I've never seen them before and they appear to lock the breaker in the "on" position. I can understand them for lockout protection when used in the "off" position, but this seem hazardous. Or am I completely off and they're totally something else? Thanks, Kiel Click to Enlarge 44.03 KB Quote Link to comment Share on other sites More sharing options...
inspector57 Posted July 29, 2014 Report Share Posted July 29, 2014 The rectangular wire "box" goes around the breaker handle when it is in the off position and the personal lockout lock of the worker goes into the loops to keep someone from energizing the circuit being serviced.

palmettoinspect Posted July 29, 2014 Author Report Share Posted July 29, 2014 That's what I thought. Should they be removed? Will they prevent the breaker from tripping when on? It looks like it will? Quote Link to comment Share on other sites More sharing options...
Marc Posted July 29, 2014 Report Share Posted July 29, 2014 That's what I thought. Should they be removed? Will they prevent the breaker from tripping when on? It looks like it will? I don't think so. The handle doesn't have to move to trip. You're just prevented from reseting it until you move it to the 'off' position.

Jim Katen Posted July 29, 2014 Report Share Posted July 29, 2014 You can't prevent a breaker from tripping by holding the handle in the "on" position. Try it. Quote Link to comment Share on other sites More sharing options...
Speedy Petey Posted July 29, 2014 Report Share Posted July 29, 2014 You can't prevent a breaker from tripping by holding the handle in the "on" position. Try it. This! They are used for critical circuits that should not be turned off for whatever reason, like alarms, smoke detectors, fire pumps, computers/servers, etc. The breaker WILL definitely trip though.

Jim Port Posted July 29, 2014 Report Share Posted July 29, 2014 Required lockouts should not be removed. They are there for safety when the equipment is being worked on. Quote Link to comment Share on other sites More sharing options...
