Plugging 30A 5th wheel into 50A service

The 50 amp service is over what you need for your 30 amp rig, one it should be more stable, two at 50 amps even if it is overloaded from too many other 50 amp rigs in the park you should have no problems with using 30 amps! The adaptor is less than $20, well worth the price! No worries you can not use more than the 30 amps that your rig is rated for! If there should be a fault your 30 amp circuit breaker will kick in and handle the emergency, and that would be a problem un related to your using the 50 amp plug!! The lack of knowledge about how electricity works makes you wonder???

The 50 amp outlets are power by the same conductors that the 30 outlets are powered from. If the park is having brownout conditions(which is low voltage because of load, and more amps are trying to flow to make up for it) on one or both of the power legs of a 50 outlet, that same condition will be occurring on the single leg of a 30 amp outlet if brownout is on both legs or on the single leg if 30 amp outlet and you are on the same brownout leg. The 30amp outlets if wired correctly should be alternating site to site between the two legs of the parks power distribution.

The worst condition people face is those with full 50 service. If the neutral lead goes bad, then 240V is placed across everything in the trailer or coach, and you burn up TVs, micro waves, converters, inverters, stereos, and sat equipment. Friend had that happen this winter in California. His bill to date is 7K and they are not done replacing things.

If you have full 50 service, have a good isolation device that will protect you from this happening.
