Electrical Diagram ?

[clonestocker]

The drafts person that did our garage drawings kinda screwed the pooch on how the electrical was to go. So now I trying to get it squared away with plan review. The reviewer is asking for a one line diagram that shows the Main Panel, Sub-Panel, over current protection devises, wiring method and wire size. I not an electrician by trade but fairly proficient at getting things done myself. Can anybody give me a better explaination on what he's asking for?

thx matt

Google is probably your best friend on this... Here's a couple links that quickly came up that look like what they are asking for.

Sounds like they need to be the ones to fix it. IF you paid them to draw them up, why arent they fixing this?

This is for a residential garage? That's a bit ridiculous to require a 1-line, IMO. 1-lines are common in commercial, industrial work where there's actually something to show on the 1-line. You'll basically have a box representing your main panel, with a description of what it is, voltage, ampacity, etc., and a line going to another box representing your subpanel in garage, with the same info for it. Add a line showing the ground rods, and info on the conductors/conduit for that and the feeder to the garage and that should do it.
