Dual voltage sockets / circuits / appliance / transformer

[ColJack]

yes all that's a problem, but since it's mainly for small kitchen appliances and he's listed things like a waffle iron, toaster, kettle etc then those shouldn't be a problem..

I don't think that a smoothie maker would be a problem either since they usually have 2-3 speeed settings anyway

it could be possible to use an inverter to supply the 120V anyway so that it could be stepped down to the correct voltage and stepped up to the proper frequency..

Wow!

Ok.... I wonder what they do in Base Housing and some building over there as some are dual voltage....

Maybe I could work the other side of the worktop separating the kitchen from the diner so as to avoid having to notify anyone to come and inspect, use a site transformer which should have enough woof for most appliances....
Pre-fuse the transformer and pre-fuse the outlet..... Covers most bases.

So these guys who run fans [ or other motors ] off of transformers are having burn-out etc problems because of frequency as opposed to voltage irregularities?

*Goes off in search of an inverter*

Thanks guys!

for arguments sake, say a motor is designed to run at 600rpm on a 60Hz supply, if you keep the voltage constant and change the frequency you'd have it running at 500rpm at 50Hz..

if it relied on that 600rpm to shift enough air over it to keep itself cool, then at 500rpm it will shift less air and start to heat up..

Gotcha!

The impedance of a winding is lower at 50 Hz than it is at 60 Hz so even if it has the correct voltage applied to the winding the current in the winding will be higher than its design current.

Providing a 115V 60Hz supply simply won't be economical unless done on a large scale (such as the enitre base would have, or the entire hotel, or a row of houses).

Far cheaper, quicker and safer to buy UK appliances. Toasters, fans and hair curlers are cheap. Transformers and inverters are not.

it's gotta cost more than it's worth to bring the things over in the first place..

I note the location and remember loads of houses in Woodbridge had 110v transformers and US sockets designed for US servicemen.

They may have been auto-transformers I did not really take a good look but seems the guys from USA had no problem with the cycles being 50Hz the transformers may have even been 3.3kv feed for all I know but split phase with 110 upstairs and 110 downstairs and 220 volt to cooker outlet.

As to converting now the standard yellow box transformer are not very good as then are not efficient you only need to see how hot they get and are centre tapped so only double insulated equipment can be used.

The larger transformers which floor or wall mount use less power and can be left on 24/7 but the price rises as a result and looking at around £150 so at that price maybe cheaper to replace equipment.

I am sure with so many houses in Woodbridge area wired 110 volt there would be no problem with LABC as they would be use to the system and so would local electricians.

Since it would come under Part P being kitchen I would say go to local electrician and ask them. They may also know where you can get transformers etc. Since this is a local issue I would say the chances of finding anyone on here who has done work in your area on 110 is slim so better to talk to locals.

For small items Look here £35 for 300W model and 45W for £10

USA voltage is 120V, but i suppose that they have tollerances as much as we do..
my american dewalt radio charger has no problems working on the 110V from a site transformer..

From somewhere I recall motor-generator sets were used at some US military installations. 230v 50Hz in and 110v 60Hz out.
