How much space between cables is enough?


I understand that proximity between power cables and interconnects or power cables and power cables is a problem, but is there a rule of thumb as to how much space is required to NOT be a problem. 1/2", 1", 6"? Also, are all cables the same? I would assume that the higher the current, the more isolation, but belief and reality are seldom the same.

Do people really want to be in the room with cables floating in the air hanging on fishing lines?
tony1954,

"Do I coil it around the water tank clockwise or counter clockwise?"

It will heavily depend on the side of the water tank you will be doing it from.
What's left of my brain hurts!
Keep wires from touching as much as possible (within reason) and enjoy MUSIC!
