I have an assortment of SQ.D Arc Fault breakers. Some are the old blue test buttons, some are the newer green test buttons, and some are the even newer white test buttons. Are only the white test buttons combination type or were some of the others also rated combination type? Nowhere on the breakers themselves do they specify series, paralell, or combination. I would like to make use of them if I still can, and I dont know if the test button color even means anything.
