Ken, different areas have different reg's. re: depth of ouside power cables. I know none of the guys I use carries a pick-axe and shovel. Others might. I don't know. You may need to hire someone to do the digging. Be sure to ask.

Here, they have to be more than 40." No telling the depth of that old gas line, unless ths gas co. has records or the neighbors can recall.

Always call the place you live a house. When you're old, everyone else will call it a home.
