Why would my main house fuse buzz when I turn on my kitchen lights? Not the kitchen fuse, but the main one. They are track lights. I've replaced the power unit on it. The lights buzz too. They are LED bulbs.

From my experience, cheaper ones buzz when dimmed and sometime buzz even at full power. When you say fuse, are you talking about switch or the breaker at the panel?

Exactly. To get technical...A Neutral is a "bonding ground" that eventually ties in to a "bonded ground" or your ground wire in the panel.

I'm on my phone and can't see your location. But typically in the US for 220V/110V panels,the Hot will be black and coming off of your breaker, the Neutral will be White and will be tied into a bar inside the panel with other white wires. That bar is bonded to the ground bar where all your Greens (grounds) are attached.

Since the Neutral carries the residual voltage or any other imbalances back to the panel to eventually ground itself, it can do some crazy things if not connected securely.

If you plan to check it, make sure you test the circuit even after cutting the breaker off with a meter. Neutrals will sometimes be shared in the field where they aren't supposed to be. So you can turn off your breaker and still have voltage sitting on the Neutral.

I've rarely seen it in homes, but in plants....especially older facilities....I have seen some screwed up wiring and that kind of stuff will get you hurt.

Words of wisdom right there. I found that out the hard way after I turned off the breaker to the lighting circuit in my shop and proceeded to cut and existing circuit in half to splice into it for an additional light above my workbench. Just about shit my pants. Will never make that mistake again. Glad it was only 110v.

mmmm neutrals.

nothing better than getting shocked over and over as you try to figure out where the fuck it is coming from...

or do it the safe way and kill power to everything and ohm the wire out. youll be able to tell what is going on with the neutral safely this way. Just sometimes takes longer and 110 makes you feel alive.

Could be a bad breaker. I've replaced two on my house.

Did you replace with normal bulbs and see if it goes away? If it is a dimming switch is it compatible with LED
