Review: Lockout protection for home panels - This is the solution if you need lockout protection for consumer breakers. Protect yourself from someone energizing the breaker you turned off, and also leave a job site with confidence that no one will energize the circuit that you're not quite finished working on. Much easier than opening the panel and lifting the lead... Be sure to have a lock that fits.
Review: Lock out - For a breaker lockout, this item is great. Easy to use and fits on most any breaker . I have used them on single pole, double pole and three pole breakers.

For a breaker lockout, this item is great. Easy to use and fits on most any breaker . I have used them on single pole, double pole and three pole breakers.

### ⭐⭐⭐⭐ Doesn't fit Square D QO AFCI/CAFCI/GFCI/DFCI
*by B***3 on October 13, 2019*

The product is well made, easy to use, and will work with many styles of breakers. However, the cam interferes with the protrusion on Square D QO AFCI/CAFCI/GFCI/DFCI breakers. If you are trying to lockout one of those then you will need a different product. I would give it 5 stars if it worked with those styles as well as traditional style breakers.
