Why Does Running Power to a Detached Garage Feel So Complicated?

I went with a 40A panel in my last place and honestly never regretted it. At first, it felt like overkill, but once I added a compressor and some extra lighting, I was glad for the headroom. The cost difference was pretty minor compared to the hassle of upgrading later. I guess if you’re 100% sure you’ll never need more, maybe it’s not worth it, but that’s a tough call... plans change.

That’s exactly what I’ve seen happen - people think they’ll never need more, then suddenly want to add a heater or some fancy task lighting and realize they’re maxed out. Did you have to do anything special for the lighting layout, or just stick with basics? I always wonder if folks regret not planning for more outlets or dedicated circuits once they start using the space for projects.

I get where you’re coming from, but honestly, I think people overthink the whole “future proofing” thing sometimes. Sure, it’s a pain if you max out your panel, but how many folks actually end up running a welder, a heater, AND a bunch of lights all at once? In my case, I just mapped out what I knew I’d use - basic LED strips overhead, a couple outlets on each wall, and one dedicated 20A for the compressor. If I ever need more, it’s not the end of the world to add another circuit or two later.

Honestly? Not really. Most people I know end up using extension cords anyway because their bench setup changes every year. Unless you’re running heavy equipment daily, sticking with basics saves time and money upfront. If you’re worried, just run conduit instead of Romex so it’s easier to pull new wires down the road. That’s been my go-to trick - keeps things flexible without overcomplicating the initial install.

I get the logic behind keeping it simple, but I’ve definitely been “that guy” who thought two outlets per wall was plenty - until I started collecting tools like they were Pokémon. Next thing you know, I’m running a daisy chain of power strips just to charge a drill and run the shop vac at the same time. Extension cords are fine until you trip over one carrying a bucket of paint... ask me how I know. If you’re already trenching and wiring, tossing in a couple extra circuits doesn’t hurt, especially if you ever want to add an EV charger or something down the line. Just my two cents from the land of “shoulda planned ahead.”

Yeah, I hear you - underestimating outlet needs is a rite of passage for anyone who’s ever set up a workspace. Here’s how I look at it from an investment angle:

- Extra circuits = future-proofing. Adds value if you ever rent or sell.
- More outlets reduce “creative” wiring solutions (and headaches).
- Dedicated lines for big stuff (like an EV charger) can save serious hassle later.

Curious - anyone here actually had to upgrade after the fact? Was it a total pain or not as bad as expected?
