8 AWG wire into 10 AWG terminal...

[Mark-]

Hello,

I am looking to put some 8 AWG wire into compression terminals like these:



And I seeking suggestion for crimp terminals or other...

I found these: (https://www.mouser.com/ProductDetail/TE-Connectivity/180599?qs=kJQ8vRrhYyd8p/Jp6dj8cw==&mgh=1)

but not sure they would be the best. This is for PV wire connections in a box. The voltage would be about 366 and 11 amps.

Other than changing the terminals to 8 AWG or using 10 AWG wire, other ideas?

Changing the terminal would be the best option.
Using the pin reducer, is the next best thing.

If you have some #10 wire and a quality splice connector like a copper split bolt, or a wire nut. NOT a wago connector.
A good crimp butt connector with a quality crimper would also work.

11A will not overheat 10 ga of stranded going into the terminal, although like others mentioned, using 8 ga terminals are the best choice.

Thanks for the responses.

@Supervstech have you had a less than glowing experience with the "WAGO Lever Nuts?"

I replace them, for a living.

So I’m not alone in bad experiences with WAGO?

Not alone, by a long shot.

Can anyone provide a link to a documented Wago lever lock issue? Are we intermingling Ideal's stab in "InSure" that are only compatible with solid wire vs. Wago lever locks?

How about a some pictures of failures that clearly show it was a Wago lever lock issue and not a an installation issue?

I don't have a failure but here are some photos of 4 I was using to extend my dryer (6000W) for around 9 months until I bought my SRNE and took the dryer off grid. No idea which were L's, N or G.
I never did get around to checking wago temp while it was running, or put the wagos back in there bin ?.
I'm not an expert nor am I trying to promote wagos, honestly they seemed sketchy to me but they worked with 0 issues or smoke.

My dryer pulls 22.5A which is about max for most of them. 10ga wago rated at 41A, so yeah it should be fine at that load. I probably wouldn’t push it any harder.

A Dinkle DK6N 8-20AWG 50A is only like $22 for a small set on Amazon, $28 for a set with jumpers...

I slept in a house for 10 years with aluminum wiring and stab-lok breakers/panel. Kept a fire extinguisher under my arm for comfort. I think you will be OK OP.

I've been to the scene of a few house fires, due to that combination.

- 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?

There’s no 8AWG wago. HVAC installer and electrician would likely use wire nuts if needed.

If you want to be pedantic terminal blocks and PDBs are also allowed but I doubt anyone bothers.

But I am confused by the need since in the majority (like 60-80%, not 99%) of cases HVAC would be connected through a disconnect box. That box will provide screw terminals. Breaker has screw terminals. So you only need wago/wire nuts/whatever if there is a splice in the middle.

You sure you need #8? HVAC wiring is sized by RLA/MCA not OCPD size. Running Load Amps, Minimum Circuit Ampacity, Overcurrent Protection. #10 is good enough to a pretty large AC. 35A RLA max which would be around 6 tons

I think I need to recheck..the current wire looked bigger than a 10awg and looked more like 8. I will confirm. I can find 10 awg wago.

I am trying to move one of my ac units to critical load panel to run via inverter/batteries

thank you

Have you tried these?
