In todays world of tech and power needs, I personally think the use of a dual receptacle is long outdated and industry needs to move to quad style per location. It’s more about accommodating all the gadgets without having power strips under beds and behind furniture making them fire hazards Considering all the things we need to add due to code changes, this can be a benefit over annoyance. BTW, let’s reinvent the blasted “outlet” and get past the single dual and develop a single quad. Ken 👍
Is there a difference between plumbing pipe (galvanized steel or black iron) and electrical conduit (I think it's called rigid metallic conduit) which appears to be galvanized steel? They look the same but the conduit costs much more. Is plumbing pipe permitted to be used according to NEC?
Hey Joel, I think you're a good teacher and an excellent speaker, but I have some comments. You said a 15 amp receptacle is only rated for 15 amps and anything higher it may melt, implying that a 20 amp receptacle would be a solution. This is false and feeds the common misconception that you need a 20 amp receptacle for a 20 amp circuit. A 15 amp "spec grade" receptacle is the same as a 20 amp except for the horizontal slot in the plastic housing. It's also code compliant in a 20 amp circuit as long as It's a duplex receptacle. The wire gauge is the gating item. Using the water analogy, 12 gauge is a bigger pipe than 14 gauge. You mentioned rating for 120 volts "nominal". By nominal I assume you mean RMS voltage. Peak voltage is approximately 170 volts and peak to peak is double that. In general, I like your channel, I recently subscribed.
"Nominal" means "or there abouts." The UPS my computer is plugged into will care if the voltage is 125 volts versus 120, but my toaster won't care. No one cares about the peak waveform voltage in electrical service like this. Everything is rated by RMS voltage.
Rigid sucks to run, better have your measurements right, bends and offsets right because it's a long walk back to the fab shop to adjust your pipe to make it right to fit
Not a knock at you, but in vernacular in general. Receptacle can also be a rubbish bin. Electric socket could be a receptacle, a light socket, or a joint. Also the word "age" added to everything. It's Amperes, volts, watts, Etc. For example, you would never pay Ohmage because that doesn't make sense. Saying voltage or wattage also does not make much sense if thought about. To me, it sounds as off as "ohmage" does. It doesn't make sense. We have a volts drop or a power failure. Not an "outage" Not sure when all this strange vernacular came about or even became acceptable but it's really annoying to people like me that hear it. I am not the only one, I am just the only one that actually speaks up about it. As for conduit, you know my answer. Galvanized stainless steel. Yes, it costs more. Yes, it will eventually rust but it's the best, especially for grounding. And when it comes to finished spaces it is a whole lot easier to fish wire through a tube than through open cavities in walls, drilled through fire stops, insulation, maybe even spray foam, and then staples. Otherwise you're tearing up drywall adding even MORE cost and delays, and complications. It will likely be over a few decades that metal conduit needs to be replace and it's the problem of the next generation. Even so, it would be easier to replace as well. As for wire gauge, I would like to see 14 wire gauge be phased out. 12 gauge is more rigid, will last longer, be better for all the crap people plug into these days. Adding strips to convert to "receptacles" into 12 or more with their space heaters, there computers, TV sets, Video Game Consoles, DVR boxes, cable boxes, satellite boxes, coffee pots, tea kettles, toaster ovens, air fryers... The list goes on forever. Especially in college dorms. Batteries are great too but they need to be recharged sooner or later, so now you have endless chargers for phones, tablets, laptops, I pads, or for me "Dewalt" power tools. That 14 gauge was fine back in the days when people only plugged in a lamp, but no one plugs in just a lamp anymore.

You are a great teacher. I really appreciate what you are doing with these videos!

Great work
Love what you’re doing, subscribed. Coming from a fellow sparky in Chattanooga TN. Looking forward to more content. Thank you!
Aren't the (usually) pre-made drops, like in a commercial setting from a junction box to a luminaire, also called "whips" ?
So informative. Thank you!

So for a 220v receptacle
