Top 2008 Code Changes
Overcurrent
Device Location
By Mike Holt
A new subsection of 240.24 addresses the installation
of
overcurrent devices in stairways.
"240.24(F) Not Located Over Steps. Overcurrent devices shall
not be located over steps of a stairway."
This change prohibits the installation of overcurrent devices over
steps in stairways. Clearly, it's difficult for electricians to safely
work on electrical equipment that is located on uneven surfaces such as
stairways. However, said overcurrent devices can be located over
landings adjacent to stairways.
