Pot lights and dimmer switches

Curious, if anyone has this is issue...I was installing the light line 4inch slim pot with dimmer switches. Dimmer say the are compatible with the pot light according to the manufacture..

When you turn on the power it crates a humming noise on the circuit breaker..

Welcome to the forums! Dimmers are compatible with the bulbs, not with the enclosures. What type bulbs are you using? Did you wire them? Did you wire them correctly?

Most breakers are thermal/magnetic and are prone to problems like that.
It's is not a cause for concern.

Yes, but the electrical panel is located in a finished basement..The dimmer switch is the issue, since they work fine on regular decora switches...I've tried 2 of there recommended dimmers and both cause the humming noise on the breakers...

Humming on the breaker is not necessarily a bad thing. I have heard it many times before. Do they work properly with the approved dimmer?

Yes they do, but it's not normal. Also I've installed these lights before and haven't had this issue...

Or if you have these lights with the same dimmer on other breakers in the same panel try them on another breaker that doesn't hum with that type of light. Further test would be the ones that don't now hum on the breaker that hums.

If you were to replace the switch(es) with regular switches, see if they hum If they don't and you like the dimmers, you'll have to live with the humming or not have the dimmers. Not many choices.

I do not have these dimmers on other breakers at this job..I have 3 different lighting circuits on breakers with these dimmers and all 3 are doing the same thing..

Ive used these lights at other jobs with these dimmers and haven't had this issue before..

I was just curious, if anyone has had this problem before..

There are too many variables here. You have the brand of lamps, brand of dimmer, Manufacture of breaker, type of breaker, voltage being applied, likely others.

The dimmer itself could cause this depending on how the dimmer dims the lamps. It could be forward dimming, symmetrical forward dimming, reverse phase, etc.

I had some LED lamps that would buzz even with "approved" dimmers. A low voltage electronic dimmer ($80) fixed issue.
