    They were cranky about the use of "romex" on a HI forum that I rarely visit, wanted either NM or Romex® used if I recall correctly. Southwire does need to protect their trademark, guard it or lose it.

    Just to add, if using the high leg & another phase for a 240V 1Ø load the circuit breaker would have to have a 240V rating, not the more common 120/240V rating.

    In a residential situation, a 30A SP breaker is a bad thing unless proven otherwise, besides a travel trailer, not much in the residential realm needs a 30A 120V circuit.

    Another hack job is that I see 2-30A single pole breakers in there, since no photos were posted of when the panel was in service can't say anything about the missing handle tie on another breaker.
