Garage Wiring Diagram

Can anyone (electrician) take a look at my wiring diagram for the subpanel in my garage and let me know if you see any problems? I have a vector PDF I can email direct for a clearer look. Limited by file size for PDF.

Why did you use images of 240V outlets on 120V circuit? You only need to use 15A outlets even thought the circuit is 20A.

Based on the picture of the Quad DP breaker it is wired wrong to the 2 outlets. The outer two handles serves one circuit and the inter two handles serves another. Your wires as pictured will split one outlet between two different breakers. That's not saying my eyes didn't get crossed when following the lines.

I'd say you don't really need to use the quad breaker unless you plan to have two people running 240V tools at the same time. Both the left and right 240V branches could be fed from a standard 2 pole breaker, just use pigtails and wirenuts to join the two branches in the panel box.

The garage ceiling receptacles need GFCI protection per code.

Good catch on the ceiling outlets needing GFCI protection. I'll add that you can't make one of the ceiling outlets a GFCI outlet, it needs to be readily accessible. So you can add a GFCI breaker or add a GFCI outlet down on the wall or use a Dead front GFCI in place of an outlet.
Readily accessible means no stools, ladders or broom sticks.

- All outlets are 20amp to match the breakers.

Based on the picture of the Quad DP breaker it is wired wrong to the 2 outlets
- You are correct, I wired those wrong, thx.

just use pigtails and wirenuts to join the two branches in the panel box
- Didn't know if I could do a pigtail inside the panel.

The garage ceiling receptacles need GFCI protection per code.
- ok, I thought I read the ceiling did not require gfci b/c it was not easily accessible.

Your diagram shows 20A 240v receptacles not 20A 120 receptacle.

As silly as it sounds.... a garage door opener needs to be on a GFI protected circuit that's easily reachable to reset. That is one reason why you cannot use a GFI receptacle AT the opener.
