Alexphd1 Posted June 21, 2017 Share Posted June 21, 2017 What would I need to run a 110v circuit for American appliances? Link to comment Share on other sites More sharing options...
ProDave Posted June 21, 2017 Share Posted June 21, 2017 A very big autotransformer, and a load of USA Sockets. If you want it to be authentic, some blank & white cored cable. This is how USAF houses used to be wired in the UK (probably still are) Link to comment Share on other sites More sharing options...
Temp Posted June 21, 2017 Share Posted June 21, 2017 How many American appliances do you have? Link to comment Share on other sites More sharing options...
Alexphd1 Posted June 21, 2017 Author Share Posted June 21, 2017 Oven & warming drawer. 240/208v 60hz Link to comment Share on other sites More sharing options...
PeterW Posted June 21, 2017 Share Posted June 21, 2017 So why do you need a 110v circuit or am I missing something .? Link to comment Share on other sites More sharing options...

If it's 208V that won't work off 240V. I had a water pump with a 208V motor. I managed to rig up an autotransformer to run it okay, but trying it on 240V direct it got very hot and bothered very quickly. Link to comment Share on other sites More sharing options...
Jeremy Harris Posted June 21, 2017 Share Posted June 21, 2017 (edited) Be aware that there may well be safety issues as well. US 230V AC is 115V AC either side of earth, I believe, not the same as the UK system of 230V AC above earth; I think it's effectively a two phase 115V AC supply to the house, with the 115V circuits from one phase and the 230V circuits using both phases in series (it's a 180 deg two phase system, IIRC). This has implications for the PE and the internal wiring and insulation within the appliance, so needs checking. It may well be OK. but it may not. I had a 230V oil cooled arc welder years ago, that was US made. It didn't mind working on 50Hz, but it did need internally re-wiring to be OK on a UK 230V AC supply.

Alexphd1 Posted June 21, 2017 Author Share Posted June 21, 2017 thank you for the good replies. I think its a non starter. Link to comment Share on other sites More sharing options...
