Hi,

Was putting a circuit in an electrical panel, and tried to get the
smallest knock-out out, but of course the largest (2"?) came out. So now
what do I do? Go get a 2" connector for a single wire or is there a
device that can close off this huge hole?

Thanks!

There are reducer washers available for this. Another option
would be a box cover with a hole for 1/2" conduit. Fasten it to the box
with a couple screws.
