I have installed a 3000A. switch board 480V.
from this board a 800A. breaker feeds to a 480V.
800A. panel (designed for air cond. loads). Also
from this panel a breaker feeds to a discounect
for the primary side of transformer and then to the transformer.The main board is properly grounded,bonded,has a grounding electrode and tyed to water ang gas.My question is if I have a
GEC from the MSB to the 800A.panel.Do I need a
grounding electrode at this transformer.
Any input on this? Thanks.
