The yellow cord shown above is for connecting your camper directly to a 30 amp, 110 volt, power pedestal available at most campgrounds,(some pedestals also have a 50 amp plug, but you are not concerned with that.)With the 30 amp cord connected to a 30 amp pedestal you can run most everything in the camper at the same time. The black adapter cord shown above is for use when there is no 30 amp, 110 volt outlet available, like maybe at home. Using it you can connect to a regular 110 volt outlet, but do not expect to run everything in the camper at once (microwave, Air conditioning, hairdryer, etc.). Capiche?
