How would i backfeed my house using a 30 amp service? Would i need to install a 30 amp generator receptacle like this?
Yes, that receptacle, 30A 2P breaker, and interlock kit is all that is needed.
You will probably have to move some circuits around in the panel because the generator breaker needs to be directly above or below the main breaker for the interlock kit to work.

i have a subpanel outside, pic below. if all these breakers are off, is there a danger of still backfeeding the lines? is interlock still needed?

The point of the kit is to ensure the main can't accidentally be flipped at the same time. It makes it impossible for that subpanel switch to be on when the generator breaker is on.
Look up your panel brand and go to:

Mine looks identical to yours, except I had double handle.
Can get the 30a/50a plug box too. Eta: as stated above, that breaker under it would need to be switched to that empty slot so gen breaker could go below.

interlok doesn't allow the power to go back onto the grid. so people working on fixing power dont get electrocuted.
sure, if you're a dumbass that didn't turn off the main.
And this myth that lineman will get electrocuted is so dumb. What do you think will happen if you try to give power to the rest of your neighborhood? Do you think every house in your neighborhood has their main off? If you send power to the grid, your generator will trip immediately b/c it obviously cannot power multiple houses. Unless someone is working on the line directly outside of your house, no one is getting electrocuted.
now the point about the male end coming loose for some reason is a very valid reason to not run through your dryer.

Engineering control vs procedural control.

Ya, not going to work for you. There are ways, but its not going to be super cheap like a normal setup.
My sisters house is like this.
For you backfeeding the dryer will be the easiest because you can shut off that 150A breaker, but there wont be an interlock for that.

ok hear me out. I have a 50 amp outlet installed on corner of house (use it to plug in my camper) and i think they put a breaker in my inside garage panel.
I was supposed to be allowed to backfeed through that plug.
If i did, and had those outside breakers off, am i safe from backfeeding into electrical lines?

Kind of getting in on the tail end of this but if I understand you correctly then yes you can hook up your generator to that 50 amp inlet box and power your main panel and sub panel but to answer your main question
“am i safe from backfeeding into electrical lines?”
Yes but ONLY if the main 200 amp breaker is OFF!
This is where the interlock comes in as others have said it forces you to turn off the main to be able to turn on the generator breaker
Sounds like you would need to move your “camper” breaker to a spot just below your main breaker
Then you can install the interlock with no worries of back feeding your secondary lines

Dude just hire a licensed electrician before you electrocute yourself or burndown your home.
If you are setting up a wholehouse generator then just go with the transfer switch.

Oh, I definitely plan on doing that. I have been shocked to many times to be fooling around with this. I just want to make sure I have everything that I need to do this. I did eliminate some generators for not have the right type of 30 amp plug. My concern now is my main disconnect is outside on the opposite side of the house and not with the panel. I don't want to buy the generator and then not be able to connect it to the house.

How old is your panel. Typically, is the main panel is say a 200 amp panel, there is a 200 amp main breaker at the top. I haven't personally seen a panel that didn't have that, except for a sub-panel

My advice is have an electrician look over house first. See what you need switch wise and how large a generator you need to run the whole house. Id say at minimum a 22kw, but you may need a 25kw. Best to know before purchasing it and switch.

Is the garage panel the panel labeled subpanel in your picture? If so, youd just need to turn that 150A breaker off. The other breakers in there for you a/c and stuff would not have power.

If he truly has a disconnect before the panel, its not required that the panel have a main breaker. There are other rules/qualifications with this, but it wouldnt be anything out the normal if his panel didnt have a main.
