In the same conduit are you allowed to run normal 60hz and also 50hz conductors? as long as they are marked? There is a conduit that was run for equipment that has controls of 50hz. We want to pull #10's through the same conduit for a small water heater, which will be 60hz. Thanks - SJT
Good Point, I'm not sure how the two HZ's would react. I'd rather not go that route if there is a possible problem. Could a wire with a different HZ induce something onto the other conductors? I guess that is the question. SJT
My old boss use to work in a big factory here in northern NJ and they use to have many different frequency lines. ( I believe they did a lot of work for satellites)What they would do is make sure that the odd frequency wires were marked and labeled with different colors. (Like purple) This way they didn't get the 120/240 red, blue, black and the 277/480 Brown, orange, yellow mixed up with the 500 Hz which was purple.
