You won't find a 16A breaker in a branch circuit.
You'd likely see a 15A
breaker (residential, probably 14Ga, maybe 12Ga wire), or a 20A breaker
(12Ga or 10Ga wire). A 15A circuit would not be safe at all, while a 20A
*might* be ok, but the system could still overload the receptacle and plug
since they are still only rated for 15A.
Wait a minute, isn't the only physical difference between NEMA 5-15 (110V,
15A) and 5-20 (110V, 20A) that one pin is rotated 90 degrees? In this
case, since residential electrical code would mandate wiring capable of
delivering 20A service on a circuit protected by a 20A breaker, wouldn't
you say that the principle reason for NEMA 5-20 existing be to prevent
user error more than anything else?
ok
