First post here, I have a practical understanding of basic electronics, but my problem is way out of my depths.

I come from the UK, just moved to Ecuador, and with me I brought a coffee machine (220-240v, 50/60Hz). Knowing it’s possible to have 240v installed in houses over here, we figured it was a good idea. That’s for the future...

Currently staying on my wife’s mother’s house whilst we house hunt. Discovered a 3-prong 250v dryer outlet in the kitchen, so decided to try and make coffee machine work here...

The UK plug is standard type G (earth/ground, neutral and live). Is there any way of fashioning some form of rewiring solution without getting into changing the mains wiring, to make this work?

I’m aware that the three prongs carry two hot wires, and the UK plug only one - any way around this? Similarly, the three prong doesn’t have a dedicated ground, but the coffee machine requires it. Any way around that?

Thanks in advance for help/advice!

  • Does this coffee pot have any electronics on it, or is it just a heating element?

    We need more information. Ecuador is half-in North American 120/240V split-phase electrical wiring, and half in Euro-style 230V 1-phase wiring (from 3-phase "wye") as you are familiar. Can you state the voltagesor shoot us a pic of the plug and/or the wiring behind? Commented Dec 14, 2018 at 19:19
  • BTW the 250V is the safety rating of the plug, not actual voltage. Just as a VR rating (210 kph) on your car's tires does not oblige you to drive that fast. Commented Dec 14, 2018 at 19:22
  • Is the outlet wired directly back to the main panel of the house, or to some subpanel somewhere? Commented Dec 14, 2018 at 23:39

The best way to do this is with a step-up transformer (like this one) that is rated to handle the amps your coffee pot needs (most convertors will not handle that much amperage so be sure to double-check).

You can't really adapt a dryer plug to Type G because they get to 240v by using two phases (120v x 2 prongs) and Type G uses a single 240v. Also, UK us 50Hz and Ecuador/US is 60Hz.
