This is exactly how swimming pool electrical installations were performed from the 1950’s thru the 1980’s. Everything changed in the early 1990’s with newer equipment and especially controllers. Simple time clocks like these were all swimming pool owners ever had until the 1990’s. New equipment and rudimentary electronic controllers were coming into play. In 2023, some of the most sophisticated electrical computerized controllers are being installed on every pool sold. Things sure have changed over the decades as I sure remember installing this old and outdated stuff. I am showing my age!!!!!!!!!!
