Hello and welcome to Just Answer. My name is ***** ***** I will be happy to assist you with your electrical question.
1) Sure, either obtain a continuity tester or a toner/probe set and you can easily identify the conductors.
2) Once each conductor is identified, they can then be color coded at each end with electrical tape with the respective colors such as black and red for the 2 hot phases and white for the neutral conductor.
Whenever testing and/or using a continuity meter or tester, make sure the conductors do not have any voltage present. Continuity testing always requires a de-energized circuit.
3) Shown in the link below is a great continuity tester. It provides an audible tone as well as a visual flashing LED indicator. This tester can perform local and remote testing to easily identify conductors.........ie....... perfect for your application.
If you have any additional questions, just let me know and I’ll be glad to answer them for you.
