outdoor illuminated sign on post

Hello. I recently had a pole sign put up in the parking lot of the small commercial building I own.
The sign company said I would need to run triplex cable to power the sign.

I have done a lot of interior wiring in the past, but never used triplex cable or run cable outdoors.

What gauge triplex cable is typically needed for this type of thing?
Can triplex cable be connected to a junction box with 12-2 ROMEX to take it back to the panel?

How is triplex connected to the panel once it is run inside the building?

Any help is appreciated.
Thanks

Triplex for a single sign is a little over kill.

When I wire a sign like that I use 12-2 UF attached to a metal guy line. 12-2 will supply up to 20A of power which is a lot of lighting.

1/8" plastic coated steel cable makes a good messenger line (guy line). Note: The messenger line must be grounded. The UF must be marked sunlight or UV resistant, most is.

AL Triplex would probably run cheaper all told when you factor in the length of the copper UF, the messenger wire and its associated hardware, etc. Also seeing what the sun has done to exposed "above-ground rated" PVC conduit on my west wall in just two years I would not trust PVC-jacketed UF for an exposed application.
