# Minimum Approach Distances (MAD) The final rule updated OSHA’s default values for transient over voltages (TOV), selecting far more conservative values. As TOV is one of the major factors for calculating MAD, this change leaves utilities little option other than to calculate of system specific TOV values. A summary of the impacts follows:
