Thank you Ryan.

While I would be quick to point out the same thing Ryan did (Red Heads not Required) when out on the job I just can not bring myself to leave the red head out even if it means a walk back to the stock area to get some for just one MC termination.

Always have used them and probably always will.

It seems like very cheap peace of mind to help prevent shorts similar to this.

Friday a 277 volt switch box blew up when energized for the first time with the device installed, the circuit has been locked out.

I have not checked it out for a cause yet, I did see the destroyed wall mount occupancy sensor and the blackened wall paint, I will check into it tomorrow and let you know what I find.

My feeling is that the load side wire from the occupancy sensor got pinched when installed, the circuit had been working before the wall sensor went in.
