That is if the cost of the recept and plug offset what extra time you would be paying for using the normal method.
I would like to see what these look like after a couple of years of use and abuse especially how the plug stands up to heat. Or at least what tests they had to go through to get them approved by UL or whoever else puts their stamp on them.
I also like the idea, again with the provision the connector is of good quality with 'tight' connections. I also really like the concept of the circuit identifier label under the outlet plate, and the 'preattached poly bag' to prevent mud/paint/grit/dust etc entering the connector. This seems a well thought out product. Now the interesting thing would be to hook one to a low voltage AC supply and feed 25 amps through it (5A greater than the breaker rating it would be connected to) for 2 weeks continuously in an enclosed space. And see what it looks like after that
This has been around for quite a while. The fact that you haven't seen them being used may speak volumes. This is a special interest item that I doubt the accountants can justify as a cost saver. The classic product in search of a market. Perhaps someone would spec this if they thought it would help the maintenance man in the future but I don't see bad receptacles as being that big a maintenance problem. Reliability wise your money is better spent in simply using a quality device with screwed in connections.
I'd be happier with beryllium-copper contacts in the plug. Brass just isn't very springy, especially at higher temperatures.
One question comes to mind: Is the "plugtail" part of the device? Here's why I'm asking.
If I install a receptacle on a multiwire circuit, NEC requires me to loop or pigtail the neutral. With this device, I assume I'd wirenut the white plugtail lead with the two neutral wires. But if the plugtail is part of the device, then that's a violation.
Even if it's not part of the device, if the receptacle is replaced later with a conventional one, disconnecting the plugtail opens the neutral temporarily, which violates the intent of the NEC.
This would definitely be a timesaver when installing a second receptacle alongside a GFCI, though.
If the "plug-tail" is installed as part of the required switched light in a room, does the rest of the device need to be installed prior to the final by a licensed professional or can it be installed by a homeowner?
