I am looking into purchasing a counter top coffee roaster that requires a 30 Amp 120 outlet; manufacturer says it uses about 21A.The only plug/circuit that can handle this load at this time is a 240 V outlet. We have a gas stove and we are not currently using the circuit.Does anyone know of a manufacturer that makes a external/freestanding step down (240 to 120) voltage transformer / regulator that I can plug into a grounded (North American) 220V outlet ? Note: a) I don't need it to be variable, just a fixed 240V to 120V is perfect. b)It would also need some sort of internal voltage regulation/ stabilization as erratic voltages would affect the (coffee) roast.
Install a 125 volt 30 amp receptacle where the oven outlet is and rewire for a neutral in the breaker panel.
If each leg of the 240v circuit is 30 amps, you won't need a transformer at all. There are travel kits for going to foreign countries that have a variety of adapters for plugging into 240V outlets that only use one leg of the circuit, which is 120v. Find the adapter that fits your outlet, and you will be up and running! DO NOT TRY TO MAKE SUCH AN ADAPTER YOURSELF UNLESS YOU HAVE A DEGREE IN ELECTRICTY/ELECTRONICS! Using a transformer involves balancing the load, getting a transformer that is rated for the current, a lot of worms in that can. There are also adapters available to stabilize the current, they are available wherever compurers are sold.
