That is the only reason to chose one or the other. If your facility has 480V, use that, there is zero reason to buy a transformer to make 230V. If your facility has 240V, installing and running power through a transformer to run the motor at 460V more than negates ANY possible savings on wire size or I^2R losses. 208V is a line to line voltage of a 208/120Y system. 220V is a line to ground voltage of a 380/220Y system. 240V is the line to ground of a 415/240Y system. The important dfference, othere than maybe having too high or low a voltage, is that one of the input leads is either ground referenced or both are hot. It can protect your item against a surge current of up to 100,000 Amps. Your equipment must be protected by a circuit breaker rated 20 – 60 amps. It is for use with 120/240 Volt, Single Phase service. This model is UL listed in the US and Canada, and has dimensions of 2.16″H x 2.78″W x 5″L. ICM517 Wet Location Surge Protector for Mini Code disallows using wire too thin for the breaker. But even if you do everything in 10AWG if you want the common receptacle, those come in 15A and 20A. Not allowed on a 30A breaker. You can still use 3-wire 240V in the USA, but must be hot-hot-ground. Baseboard heaters, compressors, hot water heaters would be wired this way. This is why more and more buildings in the US are being built using a 220v system instead of a 120v .So in reality the 220v system is the smartest thing anyone could do for their home. Also those with a 220v/240 system can always use a plug in step down transformer at any power outlet to reduce the voltage to 110/120v for other appliances Sometimes the outlet can start to smoke slightly and that’s not a good sign. Always check the device before you plug it in. 8.Is it OK to plug 220V to 110V? No. These two outlets are typically different voltages and can’t handle 220 volts. If you would like to be safe, try to buy a converter to use in different areas. Step 3 - Strip the Outer Cable Jacket. Strip the outer cable jacket by using the utility knife to gently slice through the outer insulation. Be careful while doing this to ensure you don't cut too deep and damage the insulation on the individual wires. You will want to strip the jacket back far enough you can easily land the wires on their respectable screws 3. Can a 220V 3-phase motor run on 208V? Generally, a 220V 3-phase motor is not recommended to run on 208V because the voltage drop can lead to reduced performance and potential overheating. It’s best to use a motor designed for the specific voltage supply available. 4. Can a single-phase 230V motor run on 208V? The thickness of the wire determines the amount of current that it can handle safely. The higher a wire's gauge, the thinner it is and the less current it can handle. Similarly, lower gauge wire is thicker and can handle more current. For example, #2 wire can handle 100 amps, while #16 wire can only handle 13 amps. So if 230V is within that range, then yeah. Can i use it directly with 220-240v voltage without any step down voltage converter? Can I use 110v input on a kw7Zy.
