There are these transformers and switch boxes mounted on concrete pedestals for RV Camping at Mustang Island State Park.
We’ve established that all the serious electrical power runs underground, and probably though conduit inside the concrete posts so the transforming and switching equipment can be mounted up high out of flood danger. That makes great sense.
But, if there is all that power, power for the whole RV park, running up and down through the concrete posts the transformers and switches are mounted on, why is there also that one single small wire routed separately up the side of the post like an afterthought?
What is that for, where did it come from, and why would it need to be run separately?
