TEMPO4D RTP SLOT An acceptable alternative version of the 5-20R receptacle has a rectangular slot that will only accept 5-20P plugs. Stations that do not carry news in this slot usually air syndicated fare or an infomercial; in numerous cases, educational programs can be buried in this slot or any other daytime slot as a form of malicious compliance with the mandate for such programs. There are no 1-20R and 1-30R receptacles, because 1-20P and 1-30P can mate with a corresponding NEMA 5 receptacle. There are some obsolete 1-15R or 1-20R (120 V, 15 or 20 A) receptacles which are mechanically able to accept 1-15P (120 V), 1-20P (120 V), 2-15P (240 V), or 2-20P (240 V) plugs. The 5-20R receptacle has a T-shaped neutral hole, to accept both 5-15P and 5-20P plugs. Cheater plug adapters allow a "3-prong" grounded 5-15P plug to be mated to a non-grounded 1-15R receptacle.|The Ugly {Truth|Fact|Reality} About Slot Yang Ada Rtp
