1.4 Enclosure Grounding
NOTE: Alpha Technologies recommends using the grounding method illustrated below. The
grounding method for a particular site will be dependant upon soil type, available space,
local codes, NEC (National Electric Code), and other site-specific characteristics.
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. Where allowed, exothermic welding may be used as an
alternative to Burndy clamps and connectors.
Service Grounding (required)
#6 bare copper wire from Service Neutral / Ground Bar with 2 ground rods located 6'
apart.
Lightning Protection (optional)
1/2" x 8' copper ground rod, four places, driven about 2 feet (typical) from the corners
of the pad.
#6 bare copper wire loop terminated to each ground rod and buried below grade 30
inches min. Corrosion-proof connections (25+ year life-span) and hardware suitable
for direct burial MUST be used.
