Which if it is sized OK for 40A (minimum 8 AWG, and that looks like it is OK) then used to be fine for 3-wire, so now the issue is adding a ground wire and then connecting to a modern (4-prong) receptacle while making sure neutral and ground don't connect to each other in the receptacle box. | |

I want to be sure I am clear here - the SE cable goes directly from my main panel to the receptacle box. It is black, black with red stripe and bare neutral. In my main panel, all neutrals and grounds go to the same bus. I want to do whatever is correct and safe. | |

But assuming it terminates in an actual main panel then that's OK and you just need a separate ground wire - but which needs to be kept electrically separate from the bare neutral in the junction box - simplest way may be to use a green wire rather than bare. | |

The key is that the 3rd wire is bare but not a typical ground. That cable is really meant for subpanel feeder or similar in the pre-ground days. The trick being that you have to make sure that bare neutral doesn't get grounded along the way. Simply example: If you had a main panel (neutral ground bonded) and then made it a subpanel (either new, larger, main or replaced outside meter with meter-main) then if the bare neutral is in a metal box (like the main-now-subpanel box) it is presumed to | |
