How many meters off the ground is the appropriate height for installing a distribution box
The proper installation of a distribution box involves placing it at the right height to ensure safety and convenience. While the National Electric Code (NEC) has not specified a minimum, ideal and maximum height for electrical meter boxes, the utility company does. This height also safeguards the box from potential. The minimum dimensions for depth, width and height of working space are covered in 110. 26 (A) (1), (A) (2) and (A) (3). Why do you feel that this height is an issue? On anything other than a mobil home the panel must be above ground. In a mobil home the min is 24 inches off finish floor.
