Hi,
What size and type of wire do I need to run from the electrical panel to the pump for an above ground pool that is 150 away?

What is your voltage and amps requirement? Most above ground pools all use 120 but I need to be sure. What gauge wire is on the pump motor right now?

The pump is a 0-1086-020 pool power pak 2= 115 vac-60 hz 3450 rpm 1 hp 10.0 amp motor. It is double insulated. It will be pluged into a Goldline controls aqua trol clorine generator control box that is 110-130vac 60hz 15 amp unit. It is 145 feet from the panel to a location 10 feet from the pool, The control box has a 3 ft
cord with non locking end ,(twist type). The pump is used and unfortunately we discovered tonight it was wired with a 18 gauge 25 foot extension cord. The terminal plate is missing as well so I can't answer the second part of your question knowing the proper cord will need to be installed along with the terminal cover.
