Ken, are you sure you pulled it 1200 or so ft. in the ground? A raceway is a lot different then the ups and downs that is due to unlevel surfaces. To go that far would you have to use 3 nu.6 copper wires or would something else work? Blair, you could do it in shorter runs. The electric companies here use 2 1/2 in. pipe when they bury the pipe but they usually just bury the wire as is. We have had 2 to fail on rental homes over the past few years.
