I've been surprised about the wire sizes that Coachman used in this 78 Royale. ( A review for those that aren't aware of wire sizes. And the load that a wire size can carry. Gauge size wire is based on how many wire thicknesses it takes to make one inch. #10 wire will carry a 30 amp load. #12= 20 amps, #14= 15 amps of maximum loads. These loads are based only for 110 volts AC current. ) The roof A/C units run at under 15 amps. ( more at startup. But that's under 20 amps. ) Coachman used #10 wire to each roof A/C unit. I expected #14 to be used everywhere else. But it's all #12. Coachman did a very nice job with size, and installation.Bob Dunahugh78 Royale
