Grounding Electrodes Question

[LarryFine]

Some engineers belive it helps protect electronics during lightning strikes. I bid a TV & electronics rent to own store, they wanted (3) 20' 3/4" rods, 25 feet apart in a delta configuration, cadwelded with bare 4/0 copper. All this for a 400 amp service

I can just imagine the engineer thinking "Wow, I should become an electrician! Look how much money I can make installing this stuff I'm designing!"
