Growler make your own

[John1397]

I see different growlers and the one that seems the best uses 28 gauge copper wire X 2800 turns hooked to 120 volts AC does this sound right? I think this can be figured out using ohms law to so the windings do not get hot when AC is applied.

What is a growler in this context? I see that they are beer bottles, but I don't see a need for power.

Also, if this project involves connecting to AC Mains for power, what is your experience level so far in building such projects? Are you familiar with the UL regulations for making such connections, for example?

I use the laminated core and windings from small shaded pole motors to make growlers. They are pre-designed, and available in the scrap.

The AC current is limited first by the inductance, and then by the resistance. It is the resistance that makes it hot, not the inductance.
