There is a 4 core cable wo energize the stret light pole I think I phase and neutral I s utilized what about other are two

What is the light voltage? 120, 208, 240? Sounds like a 3 conductor and a ground but you don't give us much detail.

I think you got two hots and a neutral and the fourth cable ground meaning you got 208/240 between the hots, 110/120 between a hot and neutral.
