Default How to attach 10 gauge wire to a Grainger 3PDT switch?

What's the best way to attach 10 gauge wire to this switch? Solder the wire directly to the posts, or try to find some 10g ring terminals with the small rings and try to find the tiny screws to screw the ring to the posts? Or something else?

There's 9 posts on this thing I'll have to wire to.

Thanks

Use stranded wire (Not a solid conductor) and strip a small length of insulation off of the end of the wire. Push the wire through the terminal hole Shape it and then solder it in place. ONLY use radio solder for this. Do not use plumbing solder.

I'll be using stranded wire, but the 10 gauge wire is way too big to fit thru the terminal hole. I probably could solder it to the side of the terminal.

I've got some 60/40 rosin core solder from Radio Shack that says it's for PC work. Is that OK?

I just soldered a similar switch. I peeled back half of the strands and cut them about an 1/8" from the insulation. I threaded the other half through the hole and bent them back so the two bunches were touching. I then soldered.

It is possible to enlarge the hole a little to accept the wire using a Dremel. Or just place as many strands through as possible and solder all of it. The solder you reference is exactly the one you should use for the task.

Exactly. Your description beat the pants off of what I was trying to say.

Thank You.!

Thanks huntah and PJ. I'll give this way a try. I'm a bit rusty at soldering, but I should get lots of practice over the next couple weeks.

I've been playing around in Google sketch to try to map out my future panel. I think I like this layout best so far, but may change my mind again tomorrow.

Maybe a dumb observation but isn't 10g overkill for this switch? It can't handle the power that 10g does so why not downsize the wire to the switch?

Could be I just don't understand whats going on here.

A little heat shrink can hide a lot of ugly solders.

Get the 'helping hands' set of adjustable gator clips to hold both pieces in position, a nice hot soldering iron, try to put most of the solder on the thing being soldered, practice finding a way to pill the iron off without making a solder point, and heat shrink.. 15W will not cut it for 10ga..
