to answer the question the first question is no it have to be UF cable because it is a outdoor location and it have to be sunlight proof type and the second question about running romax under siding well it can be done but i wont recomend at all i am not sure about your area and i dont know where you are located because the local codes will be diffrent than the national or state code i will just check with inspecter if any doubt about doing it best way to get a electrican who they know the area very well and they can steer you right and by the way the outdoor plugin cover are getting very strict now ( my area requird to use " in use cover " insead of flat cover but i am sure other members here can ring it here too i am sure they will tell you the same answer what i say about it above items
