Just curious...

w0lley32July 8, 2013

Hi! Where I work, in the stairway to our office, there are several electrical conduits of various sizes that run close to the handrail. I just happened to inadventently touch one of them and realized it was very warm to the touch, kind of "top of a CRT monitor that's been on all day" warm. I followed it by eye and found it feeds the overhead mercury vapor lights.

I found it strange that this particular conduit was warm, so I felt the other ones and they all are at room temperature. I would be curious to know whether this is normal or not.

I will keep your answer for myself, not do anything about it, but I am curious, to hear the answer.

Heating comes from the amount of current flowing through the wire versus it's size. Warm isn't particularly concerning.

If the warmth is not painful to the touch, the temperature is not high enough to be a concern.
