Will a breaker lock located in a panel that’s out of sight from the kiln be an acceptable means of disconnect?

Thank you.

To clarify, if the mechanism for locking out the breaker is permanently installed then it is allowed. In most case this means a "distribution" style breaker. Standard, QOB or BQ breakers don't have a permanent lock accessory.

Are you saying that the mechanism needs to be an integral part of the breaker and not an assembly that attaches to it ?

Some styles clip over the breaker and are held on by fitting tabs into indents in the breaker body.

That doesn't sound right. I've used regular breaker locks on breakers with no problems with inspectors. The lock is just to prevent someone from powering up a circuit while the load is being worked on. If someone sees such a lock on a breaker, and then turns it on anyway, that person is too dangerous to be around to start with!

I will say that "lock out-tag out" is different and would require a lock that required a key to work the lock, and a compatible breaker.
 
If the breaker is permitted to serve as the disconnecting means and is not within sight of the equipment supplied the breaker must have locking provisions that complies with 110.25 - which basically tells us the locking provision must remain in place whether a lock is in use or not.

Pretty certain the same lock attachments that fit standard QO breakers also fit QOB breakers.

No, I am saying the device must stay in place when it isn't being used.
