I know a lot of you out there are weekend Electricians, so I'd like to discuss a topic that I often get questions about. That's Breaker operation. When a Breaker is in the Oh Ef Ef position, that usually means that it was put into that position for a reason. That's not to be confused with a Breaker that has tripped, and displays the red flag. A Breaker that has tripped usually indicates an overload condition, and repeated operation of the Breaker, or changing the Breaker for a larger size could lead to this problem:
If a Breaker is in the Oh Ef Ef position, and you change it to the Oh En position, you may have the unfortunate incident of electrocuting someone. Please, PLEASE don't perform this operation without proper supervision.
However, if you find yourself in the situation of having to change a breaker from the Oh Ef Ef position, to the Oh En position, just flip it up.
If a Breaker is in the Oh Ef Ef position, and you change it to the Oh En position, you may have the unfortunate incident of electrocuting someone. Please, PLEASE don't perform this operation without proper supervision.
