Mitch, great presentation. However, the typical homeowner watching this - may be confused when the vast majority of their household receptacles are 15A and only have the two VERTICAL slots. As shown in your presentation - the 20A 120v receptacle could be easily confused with a 20A 250v receptacle. Understandably your intent was to explain Nominal Voltage (only) but this is a great example of how complex our trade can be and the many variables. Compliments to you for your expertise and your willingness to help educate those wanting to learn. Kudos big time!

Thank you for the comment. In my years of teaching nothing has been more valuable than the comments, discussions, and suggestions I am party to. I appreciate what you are saying about the receptacles. I agree. I always strive to keep things simple, but our industry makes that difficult because it is complex and ever-changing. Thank you for watching an participating!

Will you please cover safely getting 220VAC 3PH power for our hobby equipment, like lathes, planers and such?

Thank you for the suggestion. That is a pretty interesting subject. I may try to video something on that at some point. And thanks for watching!

@@takingmeasure I hope soon. I have a bandsaw, two lathes and a milling machine but only one VFD and need to build a Rotary Converter.

MITCH, most house panels use 15A breakers for the outlets around the house. Can you replace the 15A breaker with a 20A or 30A breaker to raise and increase the current? or is the outlet still going to be limited to only 15A even if you replace it with a 30A breaker.

The size of the wire is a big factor in sizing breakers. As a general rule, #14 copper must be protected with no larger than a 15A breaker, #12 copper = 20A, and #10 copper = 30A. If more than one receptacle is present on a 20A circuit the receptacles can be rated at 15A. But a single receptacle must match the circuit rating.
