Not really.
The 6.3 amp fuse will allow about 50% more current through the circuit than the 4 amp fuse. The extra drain may damage things.
4/0 (4 ought) in copper will handle 250 amps. The voltage drop at 175 ft. is about 2.14 volts which should be okay.
10 amps 250 volts or 16 amps 250 volts.
A 220 volt line may put out 250 volts because this specification features voltage that varies between 220 and 250 volts. In other countries, the electricity varies in voltage between 110-120 volts.
and breakers that can only hold up to 250 volts
12V.
Almost every home in north America will have a 240 volt supply (250 volts is the same).
To determine the amperage drawn by a 250-watt metal halide bulb, you can use the formula: Amps = Watts / Volts. Assuming the bulb operates on a standard voltage of 120 volts, it would draw approximately 2.08 amps (250 watts / 120 volts). If it operates at 240 volts, it would draw about 1.04 amps (250 watts / 240 volts). Always check the specific voltage rating for accurate calculations.
150-250 volts
Yes, that is safe.
12 Volts.
NO
The battery is 12 volts but the alternator generates about 13-14v to charge the battery.
