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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Bien material *by E***A on 3 April 2023* Me parece de buena calidad y robusto. un poco caro pero contento con la compra ### ⭐⭐⭐⭐⭐ No more accidents *by P***E on 7 January 2026* ### ⭐⭐⭐⭐⭐ Good for the price *by J***C on 28 February 2026* ## Frequently Bought Together - Master Lock Red Electrical Box Circuit Breaker Lockout, Tagout Breaker Box Lock for Standard Single and Double Toggles, 493B - TRADESAFE Circuit Breaker Lockout Device, 3 Pack, 480/600 Volt, Clamp-on Breaker Lock Out Device, OSHA Compliant, Premium Grade, Large - TRADESAFE Lockout Tagout Locks Set - 10 Red Loto Locks, Lockout Locks Keyed Different, 2 Keys Per Lock, OSHA Compliant Lock Out Tag Out Padlocks, Safety Padlocks for Electrical Lockout Tag Out Kits --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/722473639-master-lock-grip-tight-circuit-breaker-lockout-standard-toggle](https://www.desertcart.pl/products/722473639-master-lock-grip-tight-circuit-breaker-lockout-standard-toggle) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-23*
