[Shop-talk] Wiring a 230v 50hz heater for U.S. 220v 60hz supply

[Mike Rambour]

 Years ago I brought back a Raclette machine from France.   It was designed for 50hz and I wired it into a USA 60hz 220v with modified plug and it works fine, still does.  

Now you can buy raclette machines here in the USA but near 20 years ago you could not

In France (where the manufacturer is located) they're about $300. In the U.S., they're about $900. A huge chunk of that is just how common they are in France and uncommon they are in the U.S.--at home they're sold through a partner licensee.

Either cut it and wire on a dryer plug or unscrew the plug in the unit and install a dryer plug. This is also coming from a sales guy.

The function is the shape of the iron plate--the rest is just a heating blanket. I wouldn't want to switch it to 120v U.S.--it would take forever to get up to temp. and to recover during use.
