final product. The project moved around quite a bit from location to design.
I settled on a 3"x3" x 42" aluminum mounting post for a stair rail installation.
Luckily I was able to take a basketball post out of the ground and use the cement base to mount the post. I did grind the base flat but still had to use washers to level it up.
I used a 3/8" X 3 3/4" post to anchor into the existing cement. These were from Parawedge. I am not super happy with them as they don't seem to have a great grip and I feel one heavy bump on the post and they will be lose. I wish there was an epoxy type of anchor that could go in and set in the hole.
I used the Teck90 6/3 awg 1kv with the aluminum fittings. No easy feat to get the wire up the 3" tube. I suggest using a 4" if you can find it.
i set the back plate on the base and used nylon lock nuts with flat washers to secure the base plate. I used stainless steel nuts and bolts.
Once I had the wire pulled through the tube I then hooked it into the base. Set the base level and secured it, then I completed the wire setup.
Everyone says to run the extra wire for future proof but man, that crowdes things up.
Once hooked up, I secured the face plate.
I then drilled through the house and hooked into the panel.nice and tidy inside. I was able to come in right beside the panel and you don't even notice the entry. Happy with that. Once again, hard to work with those wires.
I hope this helps someone that is looking for a pedestal installation.
I would have liked to find a better mounting system to the concrete and a 4" tube. Other than that, it turned out great.
