.....Anyway, back to the subject at hand. The electrician made a series of errors that are common, but inexcusable. First, the required receptacle is an industry standard TT-30. This device has "125v-30A" molded into the face. Ignoring this info. is inexcusable. The second issue is that the terminating clamps on the back of the device are color coded, brass, nickel, and green. This is a universal color code for where to land the hot, neutral and ground, respectively. If it was a straight 220V device, it would not have a neutral screw, just two brass colored ones, and a green ground terminal. Any competent electrician has installed individual circuit conductors thousands of times, following this procedure, as every 15/20 amp. duplex receptacle is marked as such. Third, in order to "stupid-proof" the installation, it is now common to see that the manufacturer has even molded the wire color, or abreviation (I.E. "White" or a capital "W") at the entrance to the terminating clamps. Bottom line is that the electrician made an assumption, and then proceeded to ignore a lot of visual clues that should of caused him to question his assumption. The responsibility for the error, and subsequent damage, lies solely with the professional tradesmen in this case, the RV owner is competely fault free, even if he gave the electrician incorrect info. ..
