On this Elmont, NY Pool Heater we installed:

A 4×4 column posted, Column was then rapped in white plastic to match surrounding fence , attached to the post is a secured panel and power source. A conduit was trenched 18 inches below ground in PVC. This run was a home run to house main distribution panel. All power was supplied and pool heater was ready to operate, all in the same day.
