flexible stranded cable for generator inlet


I added a generator inlet and service disconnect to the outside of my house connecting to an existing inside wiring cable on the back wall. I used waterproof outdoor cable which is flexible and stranded and a friend questioned that this could be against the electrical code, that he would have used solid cable within a PVC conduit. I think I could have mounted the inlet directly at the spot where the inside wiring exits, and strung up the whole length of flexible cable as a generator extension cord. Since what I did should be an improvement over that, I don't quite understand what would be wrong with what I did. Also since this is a generator inlet circuit that is on an interlocked breaker, and will never be powered up except by the generator, during a power outage, I thought I learned that there were additional leniencies including to permit running the cable in a less than craftsman-like way. Any thoughts from someone who knows the code would be very much appreciated.

Exactly what type of cable did you use?

flexible stranded cable for generator inlet


I used 10 gauge 4 conductor cable within a rubber housing which says it is waterproof and good for 600V. I used one long piece which has aluminum strands within a yellow jacket to go from a weatherproof junction box, using wire ties to the inside wiring, to the service disconnect, which is a single 30A breaker external box which is fine for either solid or stranded wire. I used a shorter piece of identically rated but copper cable within a black housing to feed this panel from the generator inlet's 30A twist lock. I also have a short generator extension cord which will connect to the inlet from my generator's 20A twist lock which is protected by the generator's 20A breaker.

A close up picture of the label on the cable jacket? Or the overall outside view of how I ran the cables?

Just to clarify my question, I'm just trying to find out if stranded cable is prohibited for use between house wiring and a generator inlet screwed to the side of the house for rare use.

I just was curious about the overall setup on this...

Flexible cords are not to be used in the manner you described if I understand your setup.

I doubt the conductors are aluminum.
