New Shop Layout:
In this example, we have a 2-car garage that we want to convert half of it to a workshop. We're feeling spunky so we put a wall up right down the middle.
Let's assume all we have right now are the machines identified in the drawing. The table saw and the jointer are both 240V, everything else is 120V. The plan is to make the electrical rough-in as flexible as possible for future expansion and everyday workflow. The TS, jointer and DC will all be on their own circuits.
The circle with the hashtag in it is a double receptacle, the one with just 2 parallel lines is a single receptacle. Slash marks on the conduit runs represent wires, the long ones are neutrals, the shorter are hots. I did not include any ground wires in this. A ground wire is a long slash with a dot at the end of it. The numbers near the devices are circuit numbers and correspond to their location in the panel. This is for a 120/240 single phase system.
The conduit sizes are the minimum I would suggest. If I was doing this, all the branch conduits in the above drawing would be 3/4". The double receptacles will each be on their own circuit. This gives you the ability to plug two heavier loads into the same box without tripping a breaker. If you want to really dress it up, mark every box and device with their respective circuit numbers. I included a neutral with each 240V dedicated load because some require it.
Any questions, just ask.
