Incident overview

A worker was drilling holes through the exterior wall into the interior of a residential single-family dwelling for the installation of security cameras and drilled through the electrical service mast installed within the building envelope containing unfused service conductors. This caused damage to the rigid service mast and the identified conductor contained within the raceway and caused the homeowner to endure a power loss when the damage was repaired. No one was injured.
