WAGO 221-2401 Lever Nut Compact Splicing Inline Wire Connector with Case | 20 Pieces

WAGO 221-2401 Lever Nut Compact Splicing Inline Wire Connector with Case | 20 Pieces

Q: In the pictures some show as 18-14G and others as 18-12G, is it an assortment? or all one size?

These are all one size, 18-12AWG, model 221-2401.

Q: can this be used to say splice a break light on a trailer? (outdoor use)

You will have to seal them with a waterproof shrink wrap which I would double up or use a Wago Gelbox. Keep in mind that the Gelbox is only for low voltage applications. So, you can use it for the brake light. You can also use a waterproof heat shrink connector.

Q: will these pass electrical inspection? Will they pass with the NEC and most local inspectors?

Unless they are listed as an approved connection device in the NEC they will not pass inspection in commercial/residential applications for voltage over 48v.

Q: Where can I order the clear splicing 221s? It appears Wago changed the design and applied a opaque white plastic cover. The clear ones were better.

The clear ones are WAGO 221-2411. The clear 221-2411 isn't rated to support 12AWG wire while the opaque 221-2401 does support 12AWG.
