I was kind of hoping I could just merge them into 1 cable, something a bit cleaner, but wasn't sure what to do.
Marc posted a picture above. It will look better, be safer, and give you more ampacity out in the garage.

If the insulation on the wires you have up there now is cracking, it's best not to twist them together.

That is one of the most common item I used pretty often on overhead runs run the quadplex that way you can meet the code without any issue at all.

I haven't check the recent price of quadplex overhead cable yet. { For USA side }

You can able get them in 16mm˛{#6 AWG } or larger but 35mm˛{#2 AWG } is most common size I useally order.

The ampacity will varies depending on the distance and size of the conductors.

Ok Pardon my ignorance, But where does the quadplex cable tie into the service entrance? Does it just go up and down, or is it tied off somewhere?

Also, is this common/acceptable to use for a house to garage?

How are the wires at the house connected?
They should connect to the panel, and not to the service.

Well there are 2 wires coming out of a hole in the wall. Then the third is just a screw into the metal bracket on the outside of the wall. Then all three (separately) travel across the breezeway and connect to the garage.

It all looks very shady to me.

Pretty close to that and you say 3 exsting conductor some case the middle one is used for traveller for lamp useage { this part is illgeal per modern code due it will switch either hot or netural depending on the 3 way switch postion so if that the case it may be a good time to figure out and ditch that one and do it right }

Ok It took me forever to get these (was out of town for the weekend), but here they are. I will be having an electrician come out later today, but just to keep him honest, I thought I see what you guys think

The order of the photos is sorta mis-matched but it goes

1) Garage Entrance
2) Flashing and Pipe I installed, not connected, but I was planning on moving it over there somehow (the pipe still needs to be cut a bit and a Entrance Cap installed)
3) Exit from house (Only two wires coming out of house, the third is just a screw on that metal piece).
4) A Wider View of the Garage Entrance.

I have see that before many time it will be either 120/240 volt circuit OR 120 volt with farmer three way circuit for light { the latter part is illgeal if that the case } OR 120 volt circuit with one light circuit for outdoor luminaires.

So it will be one of the three diffrent set up.

Merci.

Let me ask this. I'll be running AC, Lights, Misc Tools, And other items ... none specifically requiring 240... but is there some specific setup I "should" have out to the garage? Best practice?

If you going to stay with overhead drop you will need to use the quadplex cable as I show the photo above due teh reason why you will have more than just two circuits in the garage plus what more you will have 240 volts avablile in case you have larger air compressor or welder going to be used in the garage so I know it may cost little more upfront but you don't have to regret it later if you want a 240 volt circuit.

And ., Yeah you will need a subpanel anyway if you going have more than just two circuits IMO It will be the best move if you going go that route otherwise a 4.0mm˛ triple aka 12-3 UF cable with messeger cable to support and use a double pole switch as your disconnect source and after that you can branch out one circuit for lighting and second one is for your receptales.

so there are few ways it can be done depending on big the set up you want.

And I done both overhead and underground verison.

Merci.

Yes, you should have a 120/240V system run out there. It will give you the ability to use 240V tools (compressor, welder) as well as a 240V heater. Even if you never use 240V, having (2) X 120V circuits in a MWBC setup will give you more power for less installation cost.

The exact amount of power you need is up in the air right now, but I personally wouldn't go smaller than #8 wire for a 40A 120/240V subpanel.

You installed that pipe in the roof for the purpose of running the power out to your garage? Where is the inside of the pipe located?

First of all, thanks for everyone advice, this is really helpful. I'll probably want to go with 240 then...

The pipe currently runs down into an empty panel box I installed inside the garage. I was originally not going to install any breakers in the box but perhaps I should?
