Hi,
I'm in the process of starting a barn project. The barn has been erected and now it's time to install lights etc.
What type of conduit is best? (I know loaded question) Emt tends to rust over time. Are there concerns around PVC and rodents? Primarily rats or other rodents gnawing through it?
Do any of you have experience in this area and can provide some feedback? Any help or suggestions appreciated....

Thanks
