Shore outlet

[BlakeSmith]

I just purchased a 2021 Flying Cloud. I planned on using a 220 outlet in my shop to keep it charged. Are all 220 outlets safe to connect? Where can I find a converter to get me to 50 amp and what would that be called?

Also, can you get a converter for a standard 110 outlet to the shore cord?

Do not plug into a 220 VAC supply. The 50 amp circuits on an RV & even an Airstream are two (2) sides of 110 VAC, nowhere is there a 220 volt device.

Depending on your understanding of electricity and comfort working with it (actually working with unpowered wires, junctions, breakers, etc.) it may be best to hire a qualified electrician that knows about RV & Marine 50 amp hook-ups.

About your question re adapters: If you just want to keep batteries topped off use a standard 110 VAC outlet with an adapter designed for RV/Marine use.

You can get a "dog bone" connecter to use a regular 110 outlet on your shore power cord. It will trickle charge the batteries, and run almost everything in the trailer, with the exceptions being devices that draw large amounts of power, like the air conditioning. My trailer is in storage right now connected to a 110 outlet to keep my batteries charged.

Without throwing anyone under the bus, there is a lot of mis-information out there about 50A RV power.


The voltage standard for US residential single phase power has evolved over the years from 110/220 volts to 115/230 to now 120/240. IF you measure the voltage at a "110" outlet in most places you will find it to be very close to 120 volts.


Residential service currently consists of two hot lines, a neutral, and a ground. If your "220" outlet has 4 connections it may be close to what you need for 50A service. As was said above, RV 50 amp service consists of two lines, each at 120 volts to the neutral line. If you measure from line to line you will find it is 240 volts. Nothing in an Airstream trailer is connected line to line, thus nothing sees 240 volts.


The only possible difference between a 4-wire 120/240 circuit in your shop and RV 50A service is what the size of the wire is and what circuit breaker feeds it. More than likely it will be a 20A or 30A breaker. RV 50A service has a dual 50A breaker and wire rated for 50 amps.


If you have a 4-wire "220" outlet with a dual 30A or higher breaker, with a cable wired properly for your "220" outlet it should run your trailer's 50A service just fine since nothing in your trailer draws anything close to 50 amps.


CAUTION! If you have a 3-wire "220" outlet, it does not have a neutral and cannot be used to feed your trailer. These were, and still are, typical for dryers and kitchen ranges.

They aren't uncommon in new chargers for electric vehicles either. I had a 240V, 50A outlet installed in my garage for the charger for our electric vehicle. It's a NEMA-6 50 outlet, with 3 wires. This configuration is also used in welding equipment and other shop equipment that needs 240V, sometimes found in residential garages.

The outlet in my shop was originally for a welder, which I do not have, so I have never used it. I think I may need to get an electrician to see if it is straight 220 or 2 sided 110?

Probably a safe bet to have it checked out first.

Trying to keep it as uncomplicated as possible, I agree that calling someone who knows what they are doing is your best option.

You want to ask if it is 120/240 or just 240 with ground. If there are only three pins on the outlet, it is probably 240 with ground.

Most likely, if you plug your AS into this plug, you will cause a fire and probably fire-works and cause extreme damage to your AS. Your plug wont fit, and it would require some sort of adapter. One of these adapters really should not exist for safety reasons.

Do not plug into this outlet. 220 household plugs and an RV50a is not the same and are incompatible.

Hire a licensed electrician if you cant accurately decipher the differences in these plugs with online assistance.

Thank you, everyone! I am just using a 110 outlet to keep the batteries charged.

220's are safe to connect - making sure that your electrical wiring is up to date and have ample room in your electrical box to handle loads.

You can find converters for 110 outlets (we use one for our 22FB Sport) as well as converters for 50 amp. Go to your local AS dealer, Camping World, Gander Outdoors, etc. as they would have these for you.
