Current on a 12 gauge wire

Glad the op got a resolution. Don't know why people get their nose out of joint on electrical threads. Wish tbn was like in the old days when moderators would trim those that just cause problems.

I'm not giving a deposition, nor have I tried to convince anyone to stop using aluminum wire. So, I don't have to give you my reasons.

Yep, that is what I thought.

Teacher, teacher.

Problem I see these days, are lack of men. Those are the good old days I miss.


Problem with electrical, as this thread demonstrates, is it is beyond money, and they have misinformed opinions. I suppose you would like the people correcting them to be removed?

Should we remove people who say aluminum wire is used all over?

How about you can run 100% if not for 3 hours? Remove the people that tell you that?

Here's the diagram

: One of the 120v 20a breakers will be removed and replaced with a 240v 20a breaker and one of the 12/3 romex will be extended to the breaker panel. That will handle the dishwasher and the 120v water heater. The other 120v 20a breaker
And I agree, it all needs to be checked by an independent inspector.

I probably need to re-read, and missing it. But why are you replacing with a 240 breaker, if both loads are 120?

Illegals for carprentary is probably fine.

There are big cities in Mexico, who I am sure have qualified electricians, who may be working off NEC rules. It is used all over. I realize being in Texas, maybe you ain't got a choice. But I'll run aluminum, use 1 less breaker, before I hire an electrician that does not speak english.

May it was a fluke but 20 years ago we took a vacation to Cancun. We walked the streets and I couldn't believe the number of very obvious electrical screw-ups I saw and I am not an electrician. From bare wires hanging out of boxes on the sidewalks to covers off of control panels on sides of houses. It just amazed me how shoddy workmanship was in a big town. They may have some real electricians but not where I was looking.

Of course I live in Tennessee and I some some jim-dandy stuff here also, so maybe a qualified electrician is a roll of the dice.

PS Check for a green card.

Come one, he is in Texas. We both know he doesn't want to check for a green card.

As conservative as they say they are, I suspect they are huge part of the problem. Up here tons of them are milking.

Each leg of breaker is 120, serving same purpose as tie handle.

Ok, this is because sharing neutral.


Reading up, code changed in 2008 to require a tie between the 2 circuits. Probably a good idea. I am not sure if I have shared a neutral in a long time. Most of the stuff I do is single point, or wiring a garage that would have panel or a sub panel.


I had not heard of using a 2 pole breaker, but I guess it is the same idea. Given so, no need to be scared of a string.

If you lose the neutral, you could potentialy have 240.


Myself, small subpanels have gotten very cheap. But the problem is a homeowner may not understand these. Circuit trips in sub panel, and they con't know it is there, everything fine in main. I have heard of this happening. Good labels help.

It does have me thinking, if I have any work out there, that has shared neutral.

12/14-3 is alot more common than 4 conductor. I suspect lots of places have, you pull 12-3, one for lights, one for power. Alot of them do not have tied handles. But it is a good idea.
