RV Daily Tips Issue 504; Not all 30-amp outlets are created equal

Not all 30-amp outlets are created equal.
Does your electrician know the difference?

by Steve Savage

Here’s a common mistake. An RV owner decides he wants to be able to run everything in his RV including the air conditioner. It’s convenient, to be sure, so he wants that ability at home. The next call is to a local electrician who then wires a new receptacle for the RV.Sounds good so far, but most electricians think wiring a 30-amp receptacle is a 240-volt job, like they would for a welder. The problem is an RV needs 120-volts, not that higher, welder-friendly 240 volts. That is to say, they wire the receptacle with a black, red and ground, rather than a black, white and ground.

When having a new 30-amp receptacle installed, be sure to make your electrician aware of what you need. Plugging into 240 volts rather than 120 volts makes bad things happen quickly. Normally, any 120-volt appliance that is turned on or powered at the time — think the power converter and microwave — will go up in smoke instantly when hit with 240 volts, as they are always “on.” How much else is damaged depends — although I have seen high-end entertainment systems fried, to name another common finding in these cases. Just remember, most electricians do not routinely wire for RVs, so there is no reason to assume they will automatically know what is necessary. Just say “120-volt, 30-amp circuit” and you should be free of any disaster.

This is a repost and it is only as to many people still do not take the advice, please make sure your election  knows how to wire up an RV not a home!!


About smokeycamping

Well let's see have lived in NY for my whole life, have always loved the outdoors (as long as it is warm out) have always hated the cold, and like a dummy have stayed in NY. But now with my second try my wife, we have been camping now for well over 25 yrs. We currently own a 2010 Cedar creek silverback 35TS and can not wait to get out on the highways and see this great country we all call home. Hope to see every National park before my medical issue becomes too bad to travel. I love my African gray parrot (she is my baby) and have two dogs at the time brother and sister mutts, but love them all the same. Have always been a big Nascar fan, love computers (have a number of certificates to build and work on them) am trying to learn photography, enjoy light hiking, being with good friends and folks. country music, pop music and just being outdoors. So I hope someday to meet some of the great people who like what I like and post out there in some great campground somewhere in the country, till then I will keep posting and I hope you keep liking.
