As explained in great detail 110 (or 120) applies to the voltage. 30 (or 50) applies to the current.
You have multiple 120 Volt AC service plugs:
15 Amp
20 Amp
30 AMP RV
But the "50 Amp RV" outlet is really a standard 240 VAC outlet. It's rated at 50 Amps at 240 VAC but most RVs just use the 2 hot legs independently so each leg uses up to 50 Amps at 120 VAC for a "total" of 100 Amps at 120 VAC.
