Hello guys, is it safe if i use a 10-16 A with 250v power cable to a Evga 750w psu which uses 100-240v with 10 A? Search Everywhere Threads This forum This threadYes, you can connect your laptop charger to an electrical outlet in Singapore as long as the outlet is compatible with the charger's voltage and plug type. In Singapore, the standard voltage is 230V and the standard frequency is 50Hz. Most laptop chargers are designed to be compatible with a range of voltages (dual voltage), so they should work If the power rating is given at 230V it will take rated current at 230V and more at 240V. If the power rating is given at 240V it will take rated current at 240V and less at 230V. Many heating elements only deliver rated power at their highest rated voltage, making that the worst case for current. 110 volt 30 amp wire can deliver 3,300W wattage. 120 volt 30 amp wire can deliver 3,600W wattage. 220 volt 30 amp wire can deliver 6,600W wattage. 240 volt 30 amp wire can deliver 7,200W wattage. You just have to make sure that your wire has an ampacity of at least 37.5 amps (as calculated from the NEC code).
Kevin, according to the specs for the air conditioner the circuit that should be installed would be a 30 amp 230 volt circuit using 10/2 cable with ground. The circuit breaker for this air conditioner circuit should be a 2-pole 30 amp breaker. More about Electric Circuit Wiring for a 230 Volt Air Conditioner. Air Conditioning Articles.
12 gauge NM-2 carrying 12v DC should apparently use the same current limiting as 120v AC, at about 15 amps, and for 10 gauge, 20 amps. Voltage drop may be higher with 12v in standard AC wiring, but it does not appear to be enough of an issue to worry about in a shed wired with 12v LED fixtures, with wire runs of less than say 100ft / (30m) max. I purchased a new air conditioner 230v/208v volt 250v-15A. However, plug face does not match wall outlet. Wall outlet has two big flat pins and one round pin and is bigger than the air conditioner plug face. Will I able to use a plug adapter or extension cord? By spec, can you assume that there will be 30 amps at it? No. Follow up: if you come across a L6-30R (250v, 30A), does it have to supply 240-250v, or can it supply 208, or even 120? If they are following the NEC, then they should be using the correct 120/208V outlets if the supply is 208V. OHsrpIk.
