SUMMARY

The discussion centers on the feasibility of using 28 gauge copper wire wound 2800 turns for a growler connected to 120V AC. Participants emphasize the importance of understanding Ohm's Law to prevent overheating of the windings due to resistance. Additionally, the conversation highlights the necessity of adhering to UL regulations when connecting to AC mains. A growler, in this context, refers to an electrical device used for testing shorted turns in wound armatures.

PREREQUISITES
  • Understanding of Ohm's Law and its application in electrical circuits
  • Familiarity with UL regulations for AC mains connections
  • Knowledge of electrical components, specifically shaded pole motors
  • Basic principles of inductance and resistance in AC circuits
NEXT STEPS
  • Research the specifications and applications of shaded pole motors
  • Learn about UL safety standards for electrical devices
  • Explore the principles of inductance and resistance in AC circuits
  • Investigate the construction and testing of growlers for electrical applications
USEFUL FOR

Electrical engineers, hobbyists building electrical testing devices, and anyone involved in AC mains projects will benefit from this discussion.

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.

@John1397 -- Please be sure to address these questions in your reply. Thank you.
 
Shaded pole motor is already wound if it has 3rd wire ground should be safe , refrigerator fan motor might work good.

No, just a motor with AC Mains wires and a ground wire does not describe how you are going to safely hook this up. What else is required by UL to safely make an AC Mains connection like this?

TIL about Growlers. Like dowsing but, you know, real.
