   If you connect a voltage source to what normally is considered the load side of a breaker, you are backfeeding the panel buss through the breaker. I'm guessing you may be wiring a main lug subpanel and you are backfeeding so you have a main breaker to meet a disconnect requirement. In any case you need to fasten the breaker so it can't be popped out of the panel by hand.

   The panel manufacturor provides a method to do this. The most common method is a small hole through the front of the breaker which accepts a long 6-32 machine screw . The screw engages a tapped hole in the back of the panel.

   The panel usually provides the info on the paper glued onto the cover, and it refers to using the backfed breaker as a "main" breaker.
   Sometimes you have to buy an accessory kit that has a clamp of some sort.

   Also meant to add "or the breaker can't be accidentally dislodged if the panel cover is off, etc..."

   I recently failed a final electrial. The inspector wrote
   i fasten backfed breakers.
   Can anyone explain what that is and how to correct it?
