And one more thing- the center strand in the bare aluminum conductor in that triplex / quadplex is Steel. So don't use your favorite rabbit gun to cut it! I learned of this feature the hard way.

But it does allow it to be used with very long spans between supports.

Sorry Joe, no dynamite! Too close to the house.

I am trying to dig, maybe down 12" in a lot of the 10' I have already dug, not sure I can get much deeper in places. If I put in 2" PVC for the electric runs, can a propane line be run in the same hole?

Think I read in electricians magazine you don't have to go 18 inches if you have 2 inches of concreat above the line. Guess 18 inches is insurance in case the ground errodes ( like on a hillside and water, or sand driveway plowed with a snow plow, eventually it digs down.)


One way I've seen rock quarrys "cut rock" is with 15 ft long pipes flowing gasoline and compressed air to melt the rock, but they usually cut it from the side so the lava can flow out by gravity. And in a rock quarry there's not much of anything flammable nearby so no real danger of fire..

Can always do like one staker did step up voltage to couple KV and run 2 small bare wires overhead like utility does.

I have a bunch of microwave transformers and actually briefly considered that once to temporarily get power across the street to where I wanted it. Figured one to step it up to 1500 V another in reverse and knock out the magnetic shorting lamination (current limiters). But when I thought about the risks if the wire fell I decided wasn't worth it.

Thinking about it makes you think of all the safety measures the utility uses when they do that. Very strong wire , structurally strong insulators and poles, ect....

And a body of laws from an earlier time when people were expected to have the sense not to handle bare, down wires.
