You are absolutely correct. I guess I should have been more clear.Not exactly the same. 20 amp receptacles use screws to terminate the wire end where 15 amp receptacles use friction (push-in) termination.
Those devices are what I was referring to in the quote.Of course sub par installation of any device can cause problems.
"Speed wire", "Quick wire", or whatever they want to call the devices should be outlawed, especially when people "daisy chain" through the device. (Which is also in violation of the code, but is seen too often.)
I have installed 15a and 20a duplex receptacles in all kinds of installations, from multi-family dwellings (apartment complexes) to installations at the Kennedy Space Center, and NEVER used the push-in terminations.
Sorry if it sounds like I'm attacking anyone, I'm not.
What I was trying to say is 15a receps are approved for 20a circuits, and sounded like an easy upgrade in your situation.
I personally would not use any device that is not terminated with a screw connection for anything more than a desk lamp. :serious:
The use of speedwire terminations is one of the big reasons arc-fault detection devices are now required in residential dwelling units.
One more thing to note.
The 15a rated devices that I have seen with the speedwire feature were not approved for use with 12 awg conductors. Hence the reason I assumed yours were screw terminal connected and would be an easy upgrade.
I tend to forget what Ass U Me means sometimes.:frown2:
