Electrical question.

I cannot even tell how that panel is fastened to the building

But being sloppy wouldnt cause his issues. See what happens after jumper is removed. I doubt that will solve issue though. It can be a variety of issues, usually concerning loose neutral connections somewheres. Ive also notices some brands of led lights will flicker no matter how clean of power you have.

Not so….in older homes, they only ran 3 wires between buildings and drove new ground rods at the secondary buildings. In these cases you leave the bonding jumper inplace. In more modern houses, they run 4 wires between buildings, and this is the case you dont want to bond ground and neutrals.

Good advice here, but looking at the sub panel in his picture, it appears (but maybe you see something different) that there are 4 inbound wires coming from the house. I also think I see a copper ground wire connecting the 2 busses.

Is your home’s internal wiring from breaker box to loads wired with aluminum conductors? Many homes built in the 1960s thru the mid 1970s have aluminum internal wiring.

No,

Agree, you have a modern 4 wire fed subpanel. Lose the jumper bar. And that panel is a mess. if my employee did something like that, hed be unemployed that same day.

That's beautiful.

The leds in the shop only flicker when I do laundry.

I want to thank everyone that has posted. We all have knowledge in something. Sharing that knowledge is what makes this a great place to hang out in our off time. I appreciate you all.

Yup, i refered to this after my post, before his picture appeared.

I have a few led florescent lights, 4 foot tubes, that will occasionally flicker. Its nothing to do with the wiring….its the driver in the lamp. Some leds just do this.

ive had to deal with problems with led lights for years. Especially dimmable led’s that dont dim properly.

It does sound like you have a neutral issue somewhere.

If you have a voltmeter and know how to use it, you might want to check hot to neutral and hot to ground on your problem circuits.

If you have had some requiring done, it is also possible that you have a multi wire branch circuit that someone has misfired along the way.

Multiwire Branch Circuit - Electrical 101

A multi-wire branch circuit in a residential dwelling contains two hot wires of different phases (A and B phase) and share one neutral wire as return current.

I looked and there is not a wire connecting the two busses.
