| Jul 13, 2020 at 18:23 | comment | added | Harper - Reinstate Monica | Because Amazon is a lousy place to buy electrical gear, for a litany of reasons. 1) being absolutely flooded with cheap Chinese junk, which they pay extra to SEO-boost in search results, crowding out any listings for proper electrical gear. And 2) Proper gear sellers dislike mail-order because most gear is low-value but rather heavy. Mail-order is not a good business model. A proper DPDT center off 60A switch costs a fortune. | |
| Jul 13, 2020 at 18:05 | comment | added | Nate S. | @crockeea, you have to keep in mind, the number one rule in the electrical code is that you MUST follow the manufacturer's instructions when installing anything, and so in effect those instructions (which are regulated as part of the device's UL listing process) become part of the code. So it can often be confusing to figure out the "why" of code until you also find and read the instructions of the particular device that that code section had in mind when written. | |
| Jul 13, 2020 at 16:54 | comment | added | crockeea | @PhilippNagel Yes, I saw that. But it is still confusing why that would be the case. There seems to be an implicit assumption that tripping the 20A breaker must be caused by the sum of currents over multiple receptacles, but it's not clear why this assumption matters. Anything that can go wrong with a single 5-15 on a 20A could also go wrong with multiple 5-15 on a 20A. | |

| Jul 13, 2020 at 16:37 | comment | added | manassehkatz-Moving 2 Codidact | For something like this (a) you definitely want to see a UL or comparable listing - 120V 15A is bad enough, at 240V 50A you are playing with some seriously dangerous (electrocution) power; (b) while if UL (or comparable) listed with a plastic box would be OK, metal would be inherently safer because a lose wire would be more likely to hard short and pop the breaker instead of flopping around making sparks, plus metal would contain sparks if it did. | |
| Jul 13, 2020 at 16:27 | comment | added | PhilippNagel | The key in your question is " install multiple NEMA 5-15 outlets on a 20A breaker" - you're installing only one. This would also not be legal with only 1 15A recep on a 20A breaker. | |
| Jul 13, 2020 at 16:20 | comment | added | Ecnerwal | Lack of mass market need for it. ...and shopping at Amazon, not an electrical supply house. Without looking at the link I'm guessing Chinese product - North American (or European in Europe) product would be easy to find via industrial supply or electrical supply, but not at your local hardware store unless it's unusual - though having one at all is becoming unusual... | |
