suggested distance between pull boxes. suggested distance between pull boxes. I have read your replies and I realized that I need to give much more info if I want good replies :shock: . These are runs of 1" PVC going more like 375 feet to a pull box and then continues from there. The voltage drop requires a wire size of # 4. 1. Maximum Ampacity of Outlets: The first consideration is the maximum ampacity or current-carrying capacity of the outlets themselves. In North America, most residential outlets are rated for 15 or 20 amps. If you plan to use 20 amp-rated outlets on a 20 amp circuit, each outlet can handle the circuit's full load capacity. 2.The rating of the branch-circuit short-circuit and ground-fault protective device marked on any of the controllers is not exceeded. c.
