Topic tags/keywords: conduit workshop wiring garage electric

Hello all. Hoping someone can steer me in the right direction. I have a 2 car attached garage that I’m using as my workshop. The walls are sheet rocked, I’ve installed a sub panel and in the process of running circuits. Along the back wall I built a loft for storage that runs the width of the garage, approximately 8 feet high and 8 feet deep. The underside looks like the underside of a deck with exposed joists. Now my question is this. I know along the walls I need to install circuits using conduit. I want to install fluorescent lighting under the loft. Does the conduit have to be used under the loft part as well or can I run the conduit up to the joists and then run the wiring through the joists similar to the way it’s done in a basement? Any advice is greatly appreciated.

I wonder, but, I would think this would be a great question for your local Planning & Zoning. They would be able to tell you what the code would be.

However, I often see it exposed, not in conduit. The best way is to send it through the joists, so you are not holding it up with staples, but, the staples do work.

Yes that’s exactly how I was thinking, to drill holes through the joists and run it that way. I have two outlets that the builder installed in the basement. The romex runs through and along the joists and then down into a vertical piece of conduit that is attached to the block wall. The conduit is installed as high as the joists and runs down into the outlet box.

It would depend on the local codes. I have been in areas where everything had to be in conduits. Where I live you can just run it in the attic and the walls with no conduit. They are changing now as I see 2 – 2×4’s spaced a few inches apart and wiring is laid between them. This protects the wiring from scuffs etc. So contact the local people and see what their code says. Most places have a printed spec sheet for codes that are unique to their municipality.
