4.5 Enclosure Grounding

It is the responsibility of the installer to ensure the requirements of all applicable national and local codes are

met. Alpha Technologies assumes no responsibility or liability for failure of the installer to comply with the

requirements of all applicable local and national codes.

Alpha Technologies recommends using the grounding method illustrated below. The grounding method for a

particular site is dependant upon soil type, available space, local codes, NEC (National Electric Code), and

other site-specific characteristics.
