Correct, engineer stamped attic trusses, 40 psf is just the "attic" area ~7' x 40' down the center.

Right, there is a 3/4"TG floor down already. The built in would have a vertical 2x attached to the cross tie on top and a horizontal 2x on bottom, which is screwed through the floor into bottom chords. Then horizontal 2x from the vertical 2x - attached to the vertical truss member, top with...

Ok, so how much weight could a 5'W x 2'D shelf hold? Trusses on 24" center.

My trusses are built for 40 psf, that's average material weight distributed over the square footage of the floor as I understand it. So if I have a free standing shelf that takes up 10 sf, it should be safe to hold 400lbs minis shelf weight, correct? Second question, if I build shelves that...

I am considering this since I will mostly use outlets on one side of the garage. Would this still satisfy the code requiring a 20a dedicated circuit per vehicle bay? Technically I guess it would be two 20a spit wire circuits. Yes it is the original main on the house. Ill be having a...

If I'm reading this right. I have a 125a QO and it allows a 100a 2 pole branch circuit?

Yes the AC units will be right next to the sub panel along with a 110v outlet, just didnt draw it with my awesome paint skills. So to do a load calc I would need to know the wattage of all the loads. Some of those are known but how do I account for combinations of loads or future unknown...

I think Im convinced. Main feeder to exterior 100A Sub. Feed Shed 240v 30A (more than a light and a plug in there.. Flex straight to AC units ( assuming code considers the breaker for AC unit as a disconnect ) Feed garage circuits through wall cavity. This seems to be the cleanest arrangement...

My thought process is: 4 circuits penetrating the exterior wall, main feeder, shed sub feeder, AC units - ok maybe just 3 penetrations, AC circuits could share a conduit. I dont really want 3 LB's on the side of the garage, I feel like itll get messy. With a box I can consolidate it, drops for...

My garage addition is coming along, need to update that thread, however I feel this question belongs in electrical. Planning the layout for electrical and the more I learn the less I know... Existing: Main Breaker Panel located on exterior of house, Shed sub panel fed from Main by buried 4...

Update with a few questions. Baby #3 showed up in June and Im just now getting back to working on the garage. Here's a few progress photos. At this point Ive sheathed the walls and gable end trusses, braced the trusses and put down decking in the attic storage area. Getting ready to put in...

Well I figured out why its being difficult. The truss is framed with 2x4s flat on 16" centers... starting from the center outwards. I framed my walls front to back left to right. None of my wall studs match up with the truss studs. I don't think I'll be lapping it solely because of the amount of...

Been making some progress lately. Disappointed with the contractor that did the concrete, more on that later. Currently framing the gable end wall and trying to decide/figure best sheathing arrangement. I've been doing the 9 foot walls vertical and its working great. I got to thinking that if...

Not sure where I got the 2 hour number from. City worker directed me to a "unified development code" and only requires 1/2" drywall. I find this kinda disturbing, I will at a minimum put a layer of 5/8 X on both sides of any wall adjacent to the house, including the gable end roof area, as well...

That makes sense, and easier to do. Do you know where in the code where it talks about this. I want to know if it's OK to cover the drywall with something more "decorative". Now the only question is if that portion of the wall that's doubled needs shear panels.
