Does garage wiring need to be in conduit?
Many garages contain one or more walls made of concrete or already drywalled. Cable installed on these exposed surfaces has to be protected by conduit. We show EMT (electrical metallic tubing; Photo 7), but you can also use rigid PVC conduit.
Does outdoor wire need to be in conduit?
They need to be in conduit for 2 reasons. First, exposed wiring needs to be protected from damage and stapling bare wire to the siding would not qualify. Burying it at least 24″ would qualify, but any portion above that would still need to have some sort of damage protection (conduit).
Can Romex wire be used outside?
Romex wires cannot be used outdoors because, if it gets wet with water, gas, oil or another solvent, these liquids could penetrate the jacket and ruin the connection by getting in contact with the bare copper ground wire.

Is Romex wiring safe?
Romex wire is one of the better and safer alternatives for the following reasons: Presence of a ground wire. Sheathing is flame-resistant and heat resistant, able to withstand a temperature of 90 degrees Fahrenheit. Longer-lasting due to copper metal composition.
Can you wire lights with 12 2?
Yes, it is okay to use 12-2 cable to supply lighting fixtures.
Where is Romex not allowed?
To give you an overview of what the National Electrical Code (NEC) regulations state, Romex wire shouldn’t be left exposed anywhere in the house, be it the basement, attic, or the home itself. In other words, the installation above is not compliant with the relevant codes.
Can I run Romex in garage?
Romex electrical wiring has at least two non-metallic sheath conductors under the sheath. Again, due to its flame-resistant, moist-resistant coating, Romex electrical wiring can be used in the basement, garage, or cooler spaces.
Why can’t Romex be exposed?
Sheathing on Romex is made of tough polyvinyl chloride (PVC) thermoplastic. The sheathing on both 14 and 12 AWG wire is 19 mils thick. Still, no matter how strong the NM sheathing, it is not meant for exposed applications.
What is code for wiring a garage?
Garage. As of the 2017 NEC, newly constructed garages need at least one dedicated 120-volt 20-amp circuit that serves only the garage. This circuit may also power receptacles mounted on the exterior of the garage. Inside the garage, there should be at least one switch controlling lighting.
