Electric motor research. Nov 8, 2007. #6. If you had a true 120/240V single phase meter that met the requirements of 'Blondel's Theorem', then the system would work as Rick describes. The meter would separately meter the voltage to each 'hot' conductor, and separately meter the current to each 'hot' conductor, and then register the total power Let N equal the number of turns around the transformer of each wire. The relationship between the voltage and the number of turns on each side is described by the equation: V_ {S}/V_ {P} = N_ {S}/N_ {P} V S/V P = N S/N P. This means that increasing the "outgoing" voltage is accomplished by increasing the number of turns, resulting in a step-up
By connecting the converter to two independent sources (different phases) of 120V, the 240V step-up converter creates one source of 240V power. As a result, the 240V step-up converter can power a wide range of machinery and equipment, for homes, offices, and more. It's important not to be confused with a 240v step-down converter, which takes an
Dryer wiring, especially in older homes, often does not have a ground wire - it is wired hot-hot-neutral. It's not impossible to put 120V receptacles on that, but they need to be GFCI if they do. Sometimes it uses SE cable which has a bare neutral. Further, some older dryer wiring is actually wrong and can't be used for 240V, but can be used
I spoke to my contact at Valterra and found that the # A10-5030FBK steps down a 50 amp service receptacle (2 X 120VAC) to 30 amps supply. This would work great for your camping trailers electrical system. I have linked the above mentioned product to this page for your convenience. expert reply by: Jackie C.

For 120V operation 1 & 3 would be connected to 120V Hot, and 2 & 4 connected to 120V Neutral. For 240V operation, 2 & 3 would be connected to each other and one leg of 240V would go to 1 and the other to 4. Problem is that I cannot figure out whether or if the convertible wiring applies to the motor I have. My lizard brain says surely, with all CEE 7/3 Socket. NEMA 5-15 Socket. Two-Prong Plug. Universal Socket. These transformers continuously operate at 80% of the rated power output. They convert voltage to run American appliances in Europe or European appliances in the United States. These transformers are CE Marked, which means they meet European Union safety standards.
I have a customer with a small 3000 watt inverter generator (intended for camping). At the customer's home, we installed a listed mehanical interlock for his GE 200 amp main breaker panel, a 240V-30 amp generator breaker and a 240V-30 generator inlet port. I have a standard 4 wire generator cable (L14-30P on one end, a L1430-R on the other end).
