I live in France and bought a MBP in the US and operated it with no problem (France runs on 220v). Message was edited by: tanepierre. ( 0) The current that flows through is 10 Amp when it is plugged to 110V and 5 Amp when it plugged into 220V Construction wise, a wire that conducts electricity has to be thicker when it conducts higher AMPs. I.e. in countries that use 220V the electrical wires that bring the electricity home can be thinner and thus use less copper and cost less money. Single voltage would read 120V. Household kitchen appliances like coffee makers, toasters and blenders are typically single voltage. This is usually not the sort of thing you are going to take on a trip. Dual voltage would read 110V/220V, and the device may have a switch to toggle between the 2 voltage inputs. Europe uses 230V as its standard for electricity. As a result, fans that run on 200 to 240 voltages are typically found in foreign imported equipment that was not designed specifically for the US market. If a US resident wished to directly plug a 230V fan in an outlet, he or she would require a step-up transformer to convert the outlets 120V to What happens when you plug a 220V device into a 240V outlet? In principle, any 220V device can be operated on 240V without hesitation, there is a shared increase in the performance of electric motors, e.g. if 240V falls into the 60Hz range, increase the speed of 220V generators to 240V, measure the frequency and measure you have 10 Hz gained. Step 8. Attach the wiring to the outlet, by tighten each screw on the outlet down on the wires. Connect the black wire to the brass screw, the white wire to the silver screw, and the bare wire to the green screw. Line up the holes on the outlet with the holes on the electrical box and insert a screw into each one and tighten it down. Yes, any device that is classified in 240 volts and can be used in a 220V socket. Can I plug 220V 100 240V? A dual voltage device can accept both 110-120V and 220-240V.Plug adapters do not convert electricity; converters do that, but you won’t need one for a dual voltage device. These devices should read something like 100/240V (V=voltage) or You may need a plug adaptor. Possibly dumb question: can a BMPCC 6k handle 220V? comments. 115 to 230v switch kvhKbwI.
