1	Most U.s. sockets for 20A plugs are designed in a fashion that they tin can also exist used for 15A plugs. The prototype shows a duplex socket rated at 125V, 20A (NEMA 5-20R). See nos. 5 and vi for corresponding plugs. Manufacturer: Leviton.
ii	Scheme that illustrates which parts of slots are used for 125 or 250 Volt and fifteen or 20 Amp plugs.
iii	Combined 250 Five, 15 and 20 A socket (NEMA vi-20R). This voltage is frequently used in Northward America for more heavy duty applications. Come across nos. vii and 8 for corresponding plugs. Image no. 14 shows the Canadian version of this socket. Manufacturer: Hubbell.
four	Dual amperage (15-20A) and dual voltage (125-250V) duplex socket. This device accepts each of the plugs shown in images 5 to 8. See image nos. ten and 11 for details. Manufacturer: Leviton. In that location are some more special combination duplex sockets. As well combinations of apartment bract and twist-lock devices exist.
5	15A - 125V grounded plug (NEMA v-15P). Manufacturer: Leviton, U.s..
vi	20A - 125V grounded plug (NEMA 5-20P). Manufacturer: Leviton, U.s.a..
vii	15A - 250V grounded plug (NEMA 6-15P). Manufacturer: Hawkeye, Usa
8	20A - 250V grounded plug (NEMA 6-20P). Manufacturer: Hubbell, USA

The above scheme comes with the Leviton dual amperage / dual voltage socket shown in image nos 4 and 10. Duplex sockets usually have pause-away tabs to separate the meridian and bottom outlet. In the Leviton leaflet it is indicated as Break-Off Fin. Image no. x shows a duplex receptacle with an intact fin (green arrow). Breaking the fin allows placing the two outlets on carve up circuits, each with its own billow.
Ii branch circuits may share a neutral terminating on duplex sockets, a condition sometimes referred to every bit "split-wiring", "divide-receptacle", or "split feed" (see scheme no. 12)

eleven	Split-phase wiring (run across scheme at right) allows the choice of 120 or 240 Volt in a single socket (come across nos 9-10), or separate outlets. The socket shown is a NEMA ten-20R 3 pole, 3 wire non-grounding receptacle. Brand name: Eagle Electric. The combination of slots West and Y (or X) gives 120V, whereas X-Y offers 240V. Comparable sockets be for 30A and 50A. A 15A-125V / 10A-250V variant is now phased out. For household applications (for example ranges and dryers) NEMA class 14 sockets and plugs are used, which have an boosted equipment ground wire (see examples in the heavy duty section). the matching plug is identical to the Japanese 20A separate-stage plug, and the Brazilian 20A "tristinha" plug.
12	Dissever-stage wiring, which is commonly used is U.S. homes, has two line wires ('hot' in American English), whereas the neutral wire is a grounded center-tap of the secondary scroll of the transformer; see scheme. A combination of line-i (X) or line-2 (Y) and neutral (Westward) offers 120V. Because of alternate current line-1 and -2 are out of phase and can be combined to offer 240V. The scheme is based on information given on the HyperPhysics site (Georgia Country University).
13	NEMA half dozen-20R, Canadian version. NEMA v-20R (no. ane) and 6-20R (no. 3) for the US market place have a T-shaped neutral slot so they will accept both 15A and 20A plugs. The Canadian ones have to exist designed to accept 20A plugs only. Brand name: Bryant Hubbell.
