The device here that draws 50va is drawing 4.1666 Amps at 12 volts. This is calculated as 50/12. If you're trying to measure the current draw at the mains, then that draw is 50/240, or .208 Amps.
No, it is not safe to plug a 120v 20 amp welder into a 240v 40 amp outlet. The voltage difference is too high and could damage the welder. It is important to match the voltage and amperage of the welder with the corresponding outlet.
You would need one 30 amp double-pole breaker in the breaker box for a 240V cooktop.
In the US: 120/240V. Newer homes generally have a 200 amp service.
In normal simple circuits WATTS = VOLTS x AMPS So if you use a 12V car battery 4 amps is 48 Watts American 110V mains 4 amps = 440 Watts English 240V mains 4 amps = 960 Watts
For 240V circuits, the most common wire gauge (AWG) used is 10 AWG for a 30-amp circuit and 8 AWG for a 40-amp circuit. Make sure to consult the National Electrical Code or a licensed electrician for specific wiring requirements based on the current draw of your devices.
go by a little 12v adapter at radioshack for twenty or so dollars. that's what i do and it works and even powers a amp and 4 speakers
No, you need at least a 1.5 amp power pack.
The maximum current capacity of a 30 amp breaker for a 240v circuit is 30 amps.
The recommended wire size for a 240V 30 amp circuit is typically 10 gauge wire.
The recommended wire size for a 30 amp 240v circuit is typically 10 gauge wire.
The appropriate wire size for a 240V 30 amp circuit is typically 10 gauge wire.
The recommended wire size for a 240V 50 amp circuit is typically 6 AWG copper wire.
The appropriate wire size for a 240V 50 amp circuit is typically 6 AWG copper wire.
The appropriate wire size for a 50 amp 240v circuit is typically 6 AWG copper wire.
what is the diference between 12V 15A DC coil & 12V 10 amps DC coil
yes, it is 12 volts
Yes, the larger cable can carry more load (current) than the other cable.
