Discussion Overview

The discussion revolves around the feasibility of using 28 gauge copper wire wound 2800 turns for a growler connected to 120V AC. Participants explore the electrical characteristics of the setup, safety considerations, and the definition of a growler in this context.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions whether using 28 gauge copper wire with 2800 turns and 120V AC is appropriate, suggesting that Ohm's law could be used to ensure the windings do not overheat.
  • Another participant seeks clarification on what a growler is, noting its common association with beer bottles and expressing concern about the need for power in this context.
  • A participant provides a link to a Wikipedia article defining a growler as a shorted turn tester for wound armatures.
  • It is mentioned that the inductance limits AC current, but the resistance is what causes heating, indicating a distinction in how these factors affect the growler's operation.
  • Several participants emphasize the importance of safety when connecting to AC mains, questioning the experience level of the original poster and their familiarity with UL regulations.
  • Suggestions are made regarding using laminated cores and windings from small shaded pole motors as a basis for constructing growlers.
  • There is a repeated emphasis on the need for a proper understanding of safety requirements when making AC mains connections.

Areas of Agreement / Disagreement

Participants express differing levels of understanding regarding the growler's function and safety considerations for AC connections. There is no consensus on the appropriateness of the proposed wire gauge and winding configuration.

Contextual Notes

Participants highlight the need for clarity on safety regulations and the specifics of electrical connections, indicating that assumptions about experience and knowledge may vary significantly among contributors.

Who May Find This Useful

This discussion may be of interest to individuals involved in electrical engineering, DIY electronics, or those exploring safety standards for AC powered devices.

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.
