There will be a triangle pointing towards the end of one of the wires on the connector. For single-phase, single-voltage plug-and-socket-connected equipment, double fusing ALWAYS provides protection for both kinds of faults regardless of whether polarity reversal is possible or not. White (neutral) goes on the side allocated for the larger prong. The large prong connects to the neutral wire. When an appliance is plugged into a receptacle, electric current will flow through it and then back to the larger prong, the neutral. There is no positive and negative side in a standard 110 volt AC wall outlet. This smaller slot is usually labeled as L for Line on the plug or receptacle. The right slot is the hot side of an outlet. On a plug, the hot side is also smaller. Common wire is the white neutral wire. The smaller prong of the standard polarized US receptacle receives the high voltage (approximately 120 volts effective, 60 Hz AC). To read diagram: The center positive drawing on the left indicates that the center (also known as the tip) of the output plug is positive (+) and the barrel (ring) of the output plug is negative (). You find white neutral wires tied together in circuits in the United States. 2). Next, insert the blue wire into the left pin terminal and the brown wire into the right pin terminal of the plug. I am looking at three power supplies right now. The hot side of the circuit (black wire) should be wired to the brass screws while the neutral side of the circuit (white wire) should be wired to the silver screws.
