Unlike a temporary travel adaptor, conversion plugs, when closed, resemble normal plugs, although larger and squarer. Because the AC system is set up nicely to “take back” energy from braking as readily as it “gives out” energy under acceleration, you can recover a LOT of your battery power during the normal driving process. It has a variable charging rate based on the battery voltage and solar panel voltage, and you can tune (and fine tune, if desired) the voltages delivered to the battery during the bulk, absorption, and float stages. If two voltages are 180 degrees out of phase (as is the case with the two hot legs of a US supply), the voltages don’t cancel each other out, in fact the voltage is doubled (which is where the 220/240 volt supply is derived from). There are also counterfeit plugs which appear to meet the standards (and are marked as such) but do not in fact comply. Counterfeit products are regularly seized when found, to enforce the safety standards and to protect the approval marks and trademarks of imitated manufacturers.
I guess UK works on different standards as everything is wired with hot at 230 v not two taps of 120 v which are only used on the high current stuff. Typically for a 230 volt supply to a home, the main fuse rating is 80 to 100 amps at the consumer unit. Answer: It depends on the wattage of an appliance or other load connected to a 220 volts supply. This is known as Ohm’s law and basically says that the current is proportional to the voltage and inversely proportional to the resistance (As resistance increases, current decreases and vice versa) Remember the resistance measured in ohms is just a measure of how the load or appliance in the circuit “resists” the flow of current. ALL ENGINE has the same load ,for example around 600kw of all Engine 1,2&3. And 1,&2 showing the same Amps.But for the No.3 is higher than those two Engines. Correct polarity is established by the position of the earth pin relative to the other two pins, ensuring that the line pin is connected to the correct terminal in the socket-outlet.
The earth pin also serves to operate the basic shutter mechanism used in many sockets. This amended standard adds a requirement that it shall not be possible to operate a shutter by the insertion of a two-pin Europlug, and added specifications for switched adaptors amongst others. It also added that the injury would need to be ‘pretty severe to initiate a claim’, and tripping over on a pavement may not necessarily result in a life threatening or altering injury in most cases. May 1950: BS 1363:1947 Amendment 3, title changed to “Specification for two-pole and earthing-pin fused-plugs and shuttered socket-outlets for A.C. circuits up to 250 Volts (not intended for use on D.C. circuits)”. December 1961: BS 2814:1957 Amendment 2, title simplified to “13 Ampere Switch Socket-Outlets”. January 1957: BS 1363:1947 Amendment 5, added clause permitting operation of shutters by simultaneous insertion of two or more pins (in addition to original method using only earth pin). This method is sometimes used to allow a Europlug (with two small round pins and no earth pin) to be forced into the open line and neutral ports.
The method actually adopted is described in the 1972 British Patent GB1292991. The Plugs and Sockets, etc. (Safety) Regulations 1994 permit domestic appliances fitted with non-BS 1363 plugs to be supplied in the UK with conversion plugs fitted, but not with conversion plugs supplied for fitting by the consumer. Such covers are also sometimes sold in the UK, but the shutters of the BS 1363 socket-outlet make these unnecessary. Fused plugs and sockets of various proprietary and non-interchangeable types are found in older public buildings in the UK, where they are used to feed AC electric wall clocks. In countries such as the UK, homes are fed by one of the phases plus a neutral. In other countries it is 50 Hz. Switched and unswitched fused connection units, without sockets, use BS 1362 fuses for connection of permanently wired appliances to a socket-outlet circuit. The final ring circuit in the UK requires the use of BS 1363 plugs and sockets. However, the BS 1363 system is not limited to use with final ring circuits being suitable for radial circuits. They are smaller than conventional sockets, commonly being made to fit BESA junction boxes, and are often of very low profile.
