240V feed wire has current flow feel?

Hello, I am a new member, and have a question, PLEASE.

Today I installed a new Dayton 240V/208V hanging heater, and such has a separate wall mounted thermostat. I was replacing a older Dayton unit that had lost its heat element. I followed the instructions and it fired right up and has been working fine all day. I have by habit I always check new installs after they have been on for an hour or so to see if the feed line is hot. This line is NOT HOT, but just a HINT of warmth. When I wrap my hand around the feed line I felt this current movement flow, at least this is what I call such. No shock, but just a mild vibration so to speak. I am concerned with such and would welcome COMMENTS on this.

I have double checked the wiring and all appears to be fine.

Help!!!!!

Thanks for hearing me out.

We need more details. What guage is the feed wire? What type of wire is it? Where did you feel it? How many amps and watts is the heater?

I'll also ask where you feel this? Close to the heater?
Could it be the vibration of the fan resonating down the wire?

The wire is copper AWG 6, 300V, two wire plus ground. Heater is NEW 10KW, 60HZ, single stage, marked on heater 0.55 amps, but manual says 42.0. Control is 24V.

I feel this more up close to the heater, and when the unit is NOT working. When I throw the main feed switch the feeling goes away. I replaced a similar heater and don't recall it doing this. I am using the same thermostat, and ASSUMED it to be ok to use. I don't seem to get the feel when I grasp the feed line approx. 15 feet from heater. The line is mildly warm.

Thanks,

Buzz could be from transformer.

What happens if you cut power entirely?

As I stated, when the power is killed it goes away. I am thinking it is from the transformer. My son has the same heater in his shop and I just called him and his does the same thing, so must be OK.

Thanks to all.
