GFCI use with electric breweries
« on: May 11, 2021, 11:15:44 PM »
I brew with a 240V electric induction cooker and have been "getting by" without using a GFCI.  Another thread reminded me that safety is important so I bought and put together a stand-alone GFCI unit to put in-line with the power to the cooker.  When testing it- the GFCI tripped at low power as the cooker power cycled on and off, but it didn't trip at full power.  Not exactly what I want as I boil at low power once up to temp.

I assume the large current draw when the induction cooker cycles on is the culprit.  I have no way of knowing if I'm right or if there is a larger problem with my cooker.  Anyone have an knowledge on this?

My advice is to get a licensed electrician. Better to error on the side of caution. You may need to have him change the circuit breaker with a built in GFCI.
Also, I assume the outlet is a dedicated circuit only for your device. If not, you might want to do so.

I can tell you that a GFCI in a 120v application measures the difference in amperage between the Hot and Neutral wires.  If the two leads are not perfectly identical, it indicates a “leak”.  A “leak” indicates amperage is going elsewhere and the result is a Trip.  I’m not sure how a 220v GFCI measures these values.  Perhaps you can post a wiring diagram or model number?
