My gosh 30 amps through a 10 gauge conductor? This is really on the bitter edge IMHO. Have "they" reduced the 8 AWG stranding inside a standard 30 amp RV shore power cord to 10 AWG? Down here in "minimalist land" the standard service drop for 30 ampere 127 vac service is 8 AWG.
Yes, for 30A service in both the RV and marine industries, 10 ga. is standard, 14ga for 15A circuits and 12ga for 20A circuits with 6ga being standard for 50A service. The exception would be for an exceptionally long wire run, then it would go to the next bigger size.
