Garage Wiring issues

If the cost of going to 200 amp is not an issue than go for it, who knows what you might be doing in the future. if you plan to run a welder in your garage you should consider 60 amp as a minimum for a sub panel (depending on the welding machine), being as close to the main service as it is it would not be to overly costly to go to 100 amp, then you would be able to have lots of lighting on , be welding something and your compressor can automaticaly turn on without issues. there is no logical reason other than cost to not go bigger than you need, I have seen alot of folks go the minimum then a couple years later regret it. wishing they had done more.

Also, for underground conduit, will I need SCH 40 or sch 80 PVC? Does this need to be continued into each structure up to the panel? [/quote]

Schedule 40 is used underground, Schedule 80 may be used but is more expensive.

For above ground use Schedule 80 must be use.

Garage Wiring issues

Whether you’re rewiring or adding more wiring to an older garage, or running wires in a new garage, you have a decision to make. Do you plan to leave the walls open or close them up with drywall? If you intend to leave the walls and ceiling open, you have to follow the special rules that we show here. The same goes for sheds, workshops or other structures with unfinished walls outside the living space of the house.In a house or a finished garage, electrical cable is protected from damage by permanent wall coverings like drywall, plaster or even wood, but that’s not the case in an unfinished garage. The key to safe, code-compliant exposed wiring is to use the framing members to protect and support the wires. That means not spanning stud or joist spaces with wires. Keep all the cables closely hugging the studs, plates and ceiling joists so they’re not subject to abuse (see “Dangerous Wiring Mistakes,” below).
In this story, we’ll show you a common, cost effective and code-approved way to run exposed electrical cable. But there’s one downside to this method: If you ever do decide to finish the area, you’ll have to completely rewire because the surface-mounted cables will make drywalling impossible.

Garage Wiring issues

I'd run a new conduit to the garage and put in a sub panel there. Size the wire and breaker in the house box appropriatly.

This is example of a subpanel package deal aimed at similar applications to yours -

You cannot have two separate circuits to the garage, so may as well pull out the 14 wire and run the computer and phone through the existing 1/2" conduit.

And thanks or the link to the Lowes panel. I am going to have to look into that as I think I can afford that project soon.
