Hi, does anyone know if I can get a 110v to 220v transformer in the DR and where from, I have got a generator making 220v but would like a transformer so I could plug straight into the mains.

lots of places

Yes, 110 to 220 VAC transformers are available here, in Santo Domingo in 30 de Marzo. If outside of SD, best place would be any old electrical supply or decent sized ferreteria but I am talking about straight 110 VAC to straight 220 VAC like in Europe.

The transformers I have seen here, and have one, you can plug it into 220 VAC and out come 110 VAC, or visa versa plug into 110 VAC and out comes 220 VAC.

Most gens are 110/220 unless it is From Europe or other country that predominantly uses 220 VAC mains.

Other wise 220 VAC here is generally 2 x 110 VAC mains, unless multi 220 VAC mains to produce 480 VAC.

So be sure what you got and what you really need.

g'luck!

I think it would be easier for you to ask electric company to install 220v, then have 110V and 220 V lines in your fuse box.

2x 110 VAC

For standard residential electricity in the DR/USA you have three wires of which two are hot and carry 110 VAC and one neutral which is exactly that and carries nothing in. Plus in your residence there should be a fourth wire creating a grounding circuit, mostly missing in most installations here in the DR.

So to use 110 VAC for your 'puter you plug-in to a standard tomacorriente where one line is 110 VAC and the other is neutral, the third if existing is ground and should go to earth.

For something like an AC which is usually 220 VAC it will utilize two 110 VAC lines coming in that is where you get 220 VAC and again if existing in the circuit a fourth line which is ground.

In Europe there are only two wires come in, one 220 VAC, a third local circuit for ground.

Who ever decided to use the 2 x 110 VAC circuit must had copper stocks or sold electrical supplies, because the DR/USA system needs heavier wires and more of it, the European Electric System is superior.

Like I said, make sure you know what you got and what you really need.

g'luck

Maybe I understood the question completely, and if so, delete it...

we brought in a breadmaker, working on 220 V, and even with the small transformer it did not work... so we called our tiny, funny, hilarious, playboy electrician... and gifted as he is... he transformed some plugs to produce the necessary 220-240 V...

Price-tag.... well, a marker on which he insisted so he could write clearly 240V on those plugs, and 300 pesos for the work...

Clarify

I need a transformer so I can use different electrical sockets in different locations.

What is it that you are doing?

Are you using European Appliances and Gadgets?

or are you using American / Typical Dominican available appliances and gadgets?

Example, a typical light bulb in Europe is 220 vac, here it is 110 vac!

Here typical correctly wired 220 vac uses three wires, two hot and one nuetral, in Europe 220 VAC uses two wires, one hot and one nuetral.

Note: in either case there should be one additional wire for the ground.

You really need to make clear what you are trying to do.

Clarify!

The European Connection

We have both systems (supplied by 'stacked' (synchronized) inverters) in the house, using different sockets, of course.

Is it not just so, that for a 220 V outlet two 110 V lines feed the two contacts and a third (= ground) connects to the third contact (European style)?

In some cases, when motors are to be driven, the difference 50/60 Hz gives a problem (e.g. washer, pumps, etc.), not often, though.

if you got two 110 vac lines making your 220 vac you are 100% American / Dominican set up.

reverting to you original ? makes no sense now.

you have stack inverters, perfect supplies your 110 vac and your 220 vac with two 110 vac hot wires, good.

Your house is obviously set up for the inverters.

If your gen-set is American / Dominican normal type, it should be 110 / 220 vac output.

WHY do you need a transformer????

Hi, I have a rodeo bull (bucking bronco) that I use at parties also a friend who has a bar would like to use it there but would like to do so without the noise of a generator.
