New Fuse Box Needed for 110v Electrics

[GeorgeCooke]

It's probably like the UK changing from 250V to 240V and now 230V, the actual transformers are still outputting exactly the same 250V they always were, it's just the paperwork that changed.

No, that is not the case in the US. 110v would be outside the 120v plus or minus 5% spec. Last time I was there in Brooklyn I measured the voltage at 123v.

Guess what. I had a look on the Airlink site and their transformers ARE actually 120v not 110v. OP please note.

But sadly they are autotransformers not double wound isolated types. Thus there is the possibility of 240v to earth on the output side if input polarity is reversed, a common problem with caravan sites on the continent.

Bearing this in mind I would consider a yellow site transformer a safer bet. Just use one of double the rating required.
