I fought with this for almost 30 minutes today at work. How the hell do you terminate a #10 stranded under an Ideal grounding screw in the back of a 1900?

I did my usual trick with stranded leaving a bit of insulation on the end but I cant ever get it to secure....

Put your stripper in just over an inch from the end. Strip the insulation back exposing about 1/2" oc copper. Insert your sharp scratch awl (or a skinny screwdriver in case you've never heard of a scratch awl) into the copper and hake an opening for the ground screw. remove/replace the screw.


Or, strip it back farther and expose enough to wrap it, but it likes to squeeze out. Wrap it all the way around, over itself.

Use a crimp-on terminal.
That would require a trip to the truck :laughing:

I agree with ampman, I back twist the wires for stranded terminations as well as splices, they stay together as opposed to separating. The stake on method works awesome as well.

crimped spade terminal is what I resorted to. What was taking me forever took 3 seconds with the spade terminal. I was hesitant though, are they rated for grounding?
Never heard that question asked before honestly. If it can handle the full ampacity of the conductor it's sized for I imagine it can satisfy grounding/bonding requirements.

They also make #10 solid grounding pigtails just like the #12s. Or you could make your own
Yep, there are a bunch of ways to do it, none of which involve warping stranded wire around a ground screw.

In a pinch I might use a #12 ground tail, but don't tell anybody :thumbup:
