Smile Electrical conversion 120v to 240v for New Zealand

Hi everyone, I am new to this forum, and have recently got our dream Airstream here in New Zealand. It's a 2010 Flying Cloud and we are loving it!

In order to meet the New Zealand electrical regulations, we are looking to convert the voltage to 240v. I have heard that the 110v cable rating in the Airstream is not robust enough for 240v, and need to be replaced? The cable rating for NZ needs to be 450 vac, does anyone know what the cable rating is used for late model Airstreams?

Has anyone successfully converted a 110v Airstream to 240v? This sounds like a very big project, and with much dismantling of panels required.

We are still in the planing process, and would love to gather as much info as possible, and we look forward to your feedback.

Thanks in advance.

If you can get at any if the wiring, it will be printed or stamped on the cable. I do believe however that it is a 600V rating. Also equally important is the amperage. 14 gauge wire has a 15 amp max rating, and 12 gauge has a 20 amp rating. The size of the circuit breakers are an indication of what size wire is in your trailer.
I am not familiar with NZ electrical, but if it is only 240 where one side is line 1 and the other side is line 2 and there is a ground, vs 120/240 like in the USA having a line 1, a line 2, a neutral, and a ground. So if you don't use a neutral in NZ, I would think you could change the end of the power cord and the receptacles in the trailer using the black wire as one line and the white wire as the other as long as you do not exceed the amperage rating of the wire.
Hope this helps

I suspect the wire in place is 600v. Your current draw is no higher but in fact lower by utilizing higher voltage. I am not familiar with the specs on devices local to your standards hovever I can't imagine fir example your roof A/C but likely it draws 30 amps. I think you are good.
You'll have to replace all the outlets, converter, microwave, fridge heater element and board, inverter, etc.
This should be a pretty easy swap. There is a Hella 7 pin direct swap for the umbilical cord.
How will you address your parking brake (or lack of) issue. Don't you need one when off the tow vehicle?

As stated the wire in the trailer should be rated at 600V. This will be printed on the exterior sheathing of the wire. When you pull the outlets you should be able to prove this visually.

For those of us here in the states who don't know the 240 used for typical household current around the world is not like our 240 v, it is wired like our 120v.

600v as others have said

Not much to it.

You will have to replace:
1) the converter
2) the air conditioner
3) the microwave
4) the mains panel and breakers

You will have to modify or replace:
4) The television
5) The refrigerator (I believe 230v elements are available from Dometic)

If you have an electric water heater (most Flying Cloud do not) then you would have to replace the heating element.

It isn't strictly necessary to replace the outlets, because you can purchase adapters for any appliances you use with them.

Since the lighting, water pump, and furnace are 12v and run off the converter you don't have to change them.

NZ wiring is typically 230/400v center-grounded wye.

If you have to replace the outlets for regulatory compliance reasons you may be better off removing some of them since it may be difficult to fit NZ-type outlets in the same space.

Is it 240V single phase? or Two 120V single phase that add up to 240V. It you have two 120V phases it is relatively simple. All you need to do is put in a new breaker box or even rewire the one already in the trailer. If you actually need to run everything in the trailer on 240V single phase then you are going to have to replace everything or use a step down transformer.

Thumbs up

Wow, thanks for all your replies! I love this community If the wiring is rated at 600v rating, then it should meet the NZ 450v rating, this is what the regulation says:

"All wiring systems have a rated voltage above which the insulation properties are not adequate. The minimum rated voltage for 230 volt ac systems recognised for safety is 450 volts ac. Only cables rated at or above 450 volts ac could be retained for use on circuits reconfigured to supply NZ fittings at 230 volts ac. The use of single strand cables would not be in accordance with AS/NZS 3001although this is not generally considered to be a safety deficiency provided the cable is constructed and installed to reduce the effects of movement."

The only 110v appliance inside the van is: 1. Fridge , 2. Ceiling Air con, the rest run on 12v off the converter/battery. If I can get the fridge to work at 230v easily, then I might replace the AIr con unit with a roof vent.

If I can retain the cable inside the walls of the van, it'll make a lot simpler job with this conversion, so this is the crucial point I guess.

New Zealand 240v is single phase I believe, and a normal household cable is a 3 way Red : Black : Green. I will check the Flying Cloud cable to see if it is single strain or multi. I will keep you guys posted of my progress, thanks!

The only appliance running 110v inside the van is the fridge and the ceiling Air Conditioner. All other devices are 12v powered, in which this might make things a bit simpler. I have already modified my tow vehicle with a electronic brake controller, so this is sorted with no issues at all. Thanks for checking

Don't forget your converter... that is most assuredly 110 volts!

Well spotted, indeed I will need to source a new 240v converter for this. It seems the NZ electrical compliance is very strict, and have been told by a few that I am required to completely rip out all existing cables, and rewire/retrofit everything... if this is the case then it will be a huge project, and I'd hate to see a rather new van ripped apart for this

Have talked with an electrician, and looks like we are out of luck in hoping to use existing cables in the van. Here is what is required:

"3.4 Wiring System
3.4.1 Size and type of cable
Fixed wiring forming part of the electrical installation shall consist of multi-strand insulated and sheathed cables or flexible cords having not less than seven strands and a conductor cross-sectional area of not less than 1 mm2."

If we were to convert it to 240v, looks like a complete re-wiring is needed, I'd hate to rip out working parts to effect factory condition...

You have to love regulators.

Multi strand? Really.

The 40 year old Romex in my trailer was none the worse for the wear after 40 years of hard use.

I ended up reusing all of it.
