Bought a lamp post to replace a 40 year old one that is not working. My husband found a piece of green garden hose from the basement running underground to the lamp post with a cheesy black lamp cord type of wire inside it as the electric wire. Go figure. It was installed so close to the surface, it worked it way to the surface and was run over by a lawnmower and chewed to bits.
The lamp post we purchased did not have instructions. So after doing research there are many conflicting methods...use concrete, do not use concrete. Well, our plan is to install a 22 inch hole filled with gravel on the bottom and then filled with concrete to secure the post. In regards to the electric, we plan on using # 14 outdoor direct buried wiring because the wiring for the light (switch and wall wiring is # 14). The run is about 75 feet in total. We plan on drilling a hole between the joists to get outside. And then use that grey conduit you find in the home stores and install all the way to the post and make a 90 degree bend up into the bottom of the post. We are thinking use direct buried wire for added protection, does this make sense?
Now, in regards to the lawn, we can rent a 3" trench machine for 4 hours for $75 and make the trench. We can either go across the lawn or under a paver walkway from the post to the basement. Is under paver walkway a bad idea? It would avoid the grass damage issue. I was thinking pull up the center pavers, trench, backfill, and replace the paver. How did would you go?
