How To Extend Short Wires In An Electrical Panel

WAGO 221-413 or the 221-2401 make quick work of extending short wires to reach a new breaker location in your electrical panel. If you do not feel safe performing this work yourself please call in a licensed electrician.

Comments on this video are probably the best conversations I've read in a while. Lots of good questions and almost everyone has real, helpful info. Thanks for the vid and the great comments.

IIRC the top/ bottom and sides are considered gutters or wireways and can have splices as long as they don't exceed 40% of cross sectional area for conductors and 75% for splices.

I love how something as simple as this place inside a panel has five different according to five different people. It may not be the ideal way for some people, but it's obviously still permitted.

Those inline have two sizes so if you are joining #12 be sure to get the one specifically rated for #12 wire.

You should make sure you are moving the circuit to the same phase if it is sharing a neutral

WAGO also makes a lever-less inline compression butt connector similar to the sharkbite fittings for plumbing. Used with glue walled heat shrink tubing will ensure a water tight connection equal to a solid run wire.

Interesting! I can't quote the exact NEC code on this. But, doesn't it say somewhere that you can't make additional junctions within a panel?

The other caution for those who will use this knowledge to work on the shop wiring in commercial spaces be sure that you do not have a 3 phase stinger leg which is 240 volts all on its own. Those 120V gizmoz don't like it much.

You can't use the panel as a junction box.

Careful moving breakers around. You may overload the grounded conductor in the raceway or cable.

Big Q/A is the connector will throughout 15A-30A?( without overheat melting or not). So I still use nut +heat shrink cover. At NJ 1-2 wires be extended is ok pass inspection.

The better way is to keep your wires longer in the first place

[marksheltonswork]

I am tired of making comments on this video. The most important thing you should know being an electrician is that a loose connection is the worst thing you can do. That is physic. Make sure that your WAGO's are good and tight because if they are not than what good are you as an electrician.

What about crimp on butt splice connectors like one might use for car wiring? Are they Code compliant to use for 120/240 VAC?

[lyfandeth]

And this is ok under code? As long as the splice is inside the metal breaker box?

[TrevorSachko]

Who would have thought that making all the tails in the board the same length was a bad idea...

[Painfulwhale]

Can you use Wagos on a 10g wire such as would be used for 220v water heaters/ac unit, furnace?

[Seemsayin]

Isn't a connection, like this, NOT code?
I heard that you must attach a box, with conduit to the panel, run the short wire into it, connect the extention with a marrette wire nut, and run it to the breaker.

It would be nice if Wago comes out with one in and two out

[Adawg]

20+ wires coming through 1 hole... seems legit
