Comparison of NYY-J and NYY-O cables
| Comparison criterion | Ny-j | NYY-O. |
| Protective driver | Includes a yellow-green earth thread (protective driver), offering additional protection | No protective driver, requires a connection to the earth by other means |
| Identification of conductors' colors | Yellow-green earth thread + Other color threads (For example, brun, noir, gris) | Blue neutral thread (so present) + Other color threads (For example, brun, noir, gris) |
| Driver type | Solid driver (RE), twisted driver (RM) or sector -shaped driver (SM), According to the transverse section chosen | Identical to NYY-J, The type of driver is determined by the transverse section |
