Wire nut question

I have always twisted the connections with #12 and #14 wires. I like to see the connection and know that it is solid. When using the wire nuts how can I be sure I'm getting a good solid connection, just uneasy about not seeing the wires.

I generally connect 3 or 4 #12 and believe I should use the red wire nuts, is this correct?

Any good tips to ease my mind and insure good connection?

Thanks to all who have replied to all my post!

I am a fanatic about this too. When I first started using twisters I would tighten them so far that the plastic broke, till I learned when to stop.

I use my 5/16 nut driver for the tan and side cutters for the red. I learned to just hold all the ends even (or let the stranded stick out just a bit if one is mixed with solid) , cap and twist, then forget about it.

Since I have not gotten many call backs, I guess I am doing ok.

On the wirenut bag or box there should be a list of how many of what size they are rated for. I usually put up to 3 no 12 in a tan and four to six in a red. on the low side tans are good for two 14s but two 16s don't do as well.(

(the 16 are from doing controls work.)

I typically use stranded wire and have no desire to pre-twist. If using solid wire, I generally do not unless I have more than 2 wires and that is just to control them while I am installing the wirenut.

It seems many (if not most) of the folks here prefer to pre-twist.

There is no color standard with wirenuts so you need to consult the manufacturers specs as to the limitations of their specific color applications although typically a red from most manufacturers would be proper for your application.

The instructions on one of the brands I use does insruct to continue twisting the wires until they are twisted (outside the nut) a couple rotations. After twisting, I pull on each individual wire. If they come out, obviously the conection was improper. If they appear to be loose, I remake the joint.

where in SW Mi are you? I am from Niles myself.

There's no right answer as to whether to pre-twist, but I think tugging on each wire after the nut is on to make sure they're all in tight is a good idea.

The old timers I trained with told me to pre-twist and don't put the nut on unless the twist would hold on its own.
Since then, I've done it both ways using common sense and gave it a tug to check the security.
When in doubt......pre-twist.
