While accepted as "permanent", there are none, that I really think of as permanent.Just curious what type of lockouts you guy use when they are "permanent" on a breaker. The type with a screw that locks it in place or the one with the hole for the padlock?
The breaker locks that "snap" on to the breakers and held in by the dead front cover are lucky to stay in place with one lock on. (this applies to the typical single pole 1" wide breakers)We always used a device that could accommodate up to about six padlocks. If that was insufficient, we could attach another device in one of the six holes and so on.
