ECN Forum Forums Code Related Discussion NEC & other Code issues Barn Electric

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

We use primarlity rigid pvc for ag buildings. Keep the conduits up high where the livestock can't reach them.

I've never seen a case where a rat chewed through pvc. They do seem to like the flavor of thhn insulation, however.
