Mounted Tub

Is it permissible to connect a spa with a non-metallic conduit above the ground (mounted on an exterior wall of the house)?
Planning to install spa. I've done it before, but always through. With the location of existing public services, this would be very hard. It seems easier to find around the house and under the bridge. The situation is such that the physical damage and sunlight should be minimal. What do you think? Also, does anyone know what the electrical code says about this? Planning on using 6AWG 1 1 / 4 or 1 1 / 2 light sunlight resistant gray PVC pipe. Thanks in advance for your contribution. Craig Yes for GFCI. Code requires a cut of more than 5 meters, but less than 15 meters from the resort. I had planned to go with a "package" of Lowe's or Home Depot you have the box and 50A GFCI.
My husband is an electrician, and he looked in the code book to the most recent response to this question. He said no could not find any thing that says this is not correct. He said certainly going to www.neccode.com and ask questions about their country, just to make sure. Good luck and enjoy the spa!
