Humming noise from electrical wire

Hello everyone.

I have a carrier heat pump with auxiliary heat coil rated at 15kw.
Model # is KFCEH1501F15

When the heat is turned on (that mean all electric and no thermopump)
there is a humming noise coming from the electric wire outside the house.
The main wires are tied to the wall of my house and when inside I can clearly
ear the noise and some vibration to the wall.

The noise is not coming from the unit itself. It's really from the main power wires.

I know that 15kw is a lot of power but why I ear that and can I do something
to avoid that?

I have a 200 amp main circuit panel.

Thanks for any input of what I should do!

Call the power company or an electrician.

humming wires could mean you have something thats shorted to ground that should not be and could be dangerous ,call you hvac service provider asap

what they said^^^

15kw is definitely a lot of power. It's sometimes spread across 2 circuits to keep a single breaker under 60Amps. More ower means bigger potential boom is you have a a bigger arc flash from something going to ground suddenly. Defnitely get it checked out. Could even be an issue with the pwoer companies equipment at the pole.

Me scared of huming wires.

Is your main circuit panel mounted on the same wall where you hear the electric hum? The hum could be in the panel itself, and is telegraphing the sound out from there. Regardless, get the power company and a licensed electrician involved. Better safe than burned out house.

I personally can't think of a single instance where humming wires, of any kind, are a good thing.

Start by calling the power company and explain to them what you are hearing and where. They will either come out and investigate or tell you that because of where the noise seems to be coming from you need to call an electrician. Either way, you should get it checked out.

Well the eater is on a 100amp breaker circuit and the thermopump is on another smaller circuit.

When the eat is on, even the meter outside do some noise.

But thanks all, I didn't know it could be dangerous, I will call the power company first and see from there what they think.
