My daughter's pool pump, which was hard wired, failed due to exposure to weather over the winter after several years. We are going to purchase a new pump today 1-1/2 Hp. I would like to make the new pump removable with a cord and plug. What type of plug and what size wire cord should I use to connect it to the electrical panel that is located just 4 feet away from the pump location. It will be running on 220.
