Ok just wondering why are some of the directv power cords 10 amp 125 volts 2.5 amp 125 volts 7 amp 125 volts. Direct tv claims it don't matter which power cords goes on which receiver I have 2 h 23 1 h 24 and one hr21 pro. Moving stuff around they kinda got mixed up. I just don't want to burn down my house. Any help would be appreciated if it matters which cords go on which receiver.
