Hint: low hanging fruit
The overhead service conductors and drip loops here are way too low for this truck repair location. That large white roll-up door is the entrance to the service bay for a truck repair shop. The conductors at the drip loops are directly in the path of trucks pulling in and out of this repair shop.
For the lowest part of the drip loops, Sec. 230.24(B)(1) requires a minimum vertical clearance of 10 ft from final grade for overhead service conductors of services 1,000V or less. These drip loop conductors are no more than 8 ft above grade.
Section 230.54(C) requires the service head to be located above the point of attachment of the service drop or overhead service conductors.
To prevent the entrance of moisture, Sec. 230.54(F) requires the connections between the service entrance conductors and the service drop or overhead service conductors to be made below the service head on the raceway.
