An ac unit with a 40 amp breaker may not need 8awg.- I have to do a 8 AWG connection from main panel to sub-panel for an AC unit (40 amp breaker). What would be the best way to connect them?
- Wago
- wire nut connectors
- what else?
What Wago connector would I use for 8 awg? Kinda confusing looking at their site. I don't see any 8 awg options. It would be great, if you could provide a link
Would this work?

Stab-loks were in the Federal Pathetic(Federal Pacific) panel family. Otherwise known as cheap welders!
I replace tons of those panels...
I always thought no matter what you sized the AWG to the breaker.
Can't remember for sure but I'm thinking it was them (Federal Pacific) that for a while used "EZY-WIRE as the marketing slogan for their breakers and panels.
So if this applies to conventional AC systems, wonder how inverter based mini splits, knowing there’s no such thing as max inrush.
It looks like 8 awg. Not sure why 8. The wire is not labelled so I compared the thickness..attached..white is 6awg. Green is 8awg and matches the ac unit wire(black). So I think I need to use the same. I have 2 units. 1 at 30a and one at 40a. Both are 8 awg
Are wire nuts ok for 8 awh. I got one from Home Depot
Looks very expensive
Check the compatibility chart (printed on their or PDF). The biggest and second biggest work.
It’s dual rated so you can do copper copper. It’s a “creative” use case.
I need to route directly to the sub-panel thru an existing conduit so can't use an external disconnect..One of my favorite ways to safely and reliably step up/step down wire sizes larger than #10 is with a readily available and super cheap disconnect.
This 30A disconnect has lugs are rated for #14- #2AWG. Of course you're never going get wire larger than #8 to bend in that tiny box so you might have to get creative and pull the disconnect out of that tiny box but I think you can see where I'm going. Yes, it's rated for 250Vdc and the pictures aren't accurate. They are solid, we use them all the time.

You are allowed to upsize OCPD for inverter, code section just says HVAC. And often the inverter will tell you to do that. Note it’s quoted in. MCA and MOCP. You can use any breaker between MCA and MOCP. And you do not need to upsize the wire to match MOCP.
I got these. Will check out alumniconn
Yup I’ve used these big blue nuts before. Really easy to use with how well built these are, and the wings make it easy to get leverage to crank down. It’ll work with any size wire you might have in there. Can’t remember if your ground is #6 (which is insanely oversized) hopefully it isn’t since #6 has very limited splicing options with wirenuts, and you tend to need to splice ground a lot more
