Is there an electrician in the house?

Our local code says it still should be in conduit if it is not buried, I think. We had some work done on our hot tube and all the wire that runs to it is in conduit. I would think for safety you would need to do the same to prevent animals from eating the wire. But I assure you I am no electrician.
