My SquareD panel has room for almost twice as many single breakers than screws on the grounding bar. Putting two ground wires under a single screw not not make for a sturdy connection. What do people do?

An additional grounding bar can be purchased and screwed onto the back of the panel, making sure to have a good electrical contact including scraping the paint off where the new bar touches the panel.

The label on the inner door or thereabouts should tell you how to double or even triple lug a grounding wire. Most feel it's good practice to pre twist the conductors although this isn't usually required. The label should also tell you which ground bar kit to get. If not, you can download info based on the product number. Once you find the right GBK and obtain it, follow the instructions included with it. You may need a 10-32 tap

I can't seem to find a grounding bar kit - at least what I would expect it to look like. The panel is SquareD, CAT.ON.QO42M, Series T3B. The grounding bar is actually just screws on the back wall of the panel on both sides of the breakers. What would this grounding bar kit look like?

The ground bar looks like a neutral bar. They mount on raised bump on the back of the panel.

One of many for QO panels.

Do the screws have a raised lump on each side? If they do then you can put one wire on each side of a screw. They don't need to be wrapped. The lump holds them in.

This looks like the bars for neutral wires at the top of the panel. However, the ground wires are connected to individual screws that go into the back wall of the panel in a vertical row - there are not raised nor look like a bar.

I think so. But it's really hard to get a wire on either side. Do you have a picture of this?

Meant to say, it's really hard to get the wire on both sides of the screw. Do you have a picture of this to make sure we are talking about the same thing? And is it to code to do this in Vancouver, Canada?

Here is a regular expandable box with the side removed. Note the lumps beside the screws. This is a valid code ground connection in Canada.

Yes, this is what I am looking for. Thank you!

Just take note, to be code compliant the wire needs to enter so that when you tighten the screw it pulls in more not pushes out. Two wires need to enter from opposite directions.
