## Questions & Answers

**Q: Will these fit double pole breakers or just single pole?**
A: It would fit over one side of most 2-pole breakers, which would, in effect,  lock out the breaker.  This does not fit some larger 277V breakers.

**Q: Can this be knocked off with a hammer or pried off with a screwdriver?  I need it to be secure!**
A: All  the person you’re trying to prevent from using the electrical needs to do is remove the entire circuit breaker that has the lock on it  and replace it with another breaker to continue to use electricity. Not even locking the wall panel will help, the cover is held on with 4 screws

Your only opinion you have left is to place a metal cap over the breaker switch and connect the metal cap to the 220 feed leading into the panel

**Q: how wide does the jaws open?**
A: It's ment for a breaker. It will fit any breaker from the main power to the 15 and 20 amp ones

**Q: i need a device to lock breaker in on position to insure our church organ is not turned off accidently can i reverce this device to use it that way???**
A: This device is probably not what you want---it is intended to lock a circuit breaker in the "OFF" position for safe-maintenance situations...they make a breaker lock intended for locking a breaker in the "ON" position...it is intended for applications such as you describe---an alarm system, eg.,...the breaker will still trip if overloaded, but cannot be turned off by accident or un-authorized personnel.

### ⭐⭐⭐⭐⭐ Review
*by A***Z on 6 October 2023*

I bought this breaker lock-out as a reminder to not turn this breaker on, unless you really need it. I use this on the 240V, 50 AMP, Electric Vehicle / Recreational Vehicle outlet that I installed under our breaker panel. Most of the time, this should be turned OFF, but on rare occassion it needs to be turned on. This Lock-out makes it really easy to remember to keep it turned Off when not needed and prevents people from turning it on by accident. The quality of construction is excellent and although I didn't need to use the fitment accessories that came with it, I appreciate that they were included. Nothing is as frustrating as not being able to finish a project beause of a fitment issue. Master Lock had this in mind and they have you covered. Great little product. I would definately buy it again.
