20 amp how many volts?
9539
Volts = Watts / Amps 2400 Watts / 20 Amps = 120 Volts.

Locate the circuit for which you want to calculate the circuit load. Take the breaker size and multiply it by the rated voltage. For example, a 20 amp breaker that operates at 120 volts has a maximum load of 2400 watts.

These are technically all vector quantities, but since the power figure you provided is in watts (as opposed to volt-amperes), and the voltage is in RMS, then 12 watts = 120 volts x current (in amperes), or current (in amperes) = 12W/120V = 0.1 amperes = 100 milliamperes (mA).

In de meeste bestaande woonhuizen vindt u een 1 -faseaansluiting (aansluitwaarde van 1 x 35 Ampère voor elektriciteit). Er komt dan via één kabel (fase) 230 volt binnen.

Watts = Amps x Volts 10 Amps x 120 Volts = 1200 Watts.

LitePOWER 20kw generators are typically wired for Single-Phase. This gives you 83 amps @ 120 volts per leg. The circuit breaker is pre-set at 90 amps.

Knob and tube wiring is often #12 gage copper wire and can handle 20 amps. Note: Even though some knob and tube wiring is capable of handling 20 amps, we suggest that it be protected by 15 amp fuses because, in all likelihood, some modern #14 gage wire may be connected to the older #12 gage wiring.

20 amp switches are about 10x the cost of 15 amp switches. 20 amp switches double pole (always I think). You can use a 20 amp switch on a 15 amp system. Light switches (residential, anyway) are almost never double pole.

An important note to remember is that circuit breakers can only handle about 80% of their overall amperage. That means a 15-amp circuit breaker can handle around 12-amps and a 20-amp circuit breaker can handle about 16 amps.

20-amp receptacles have a horizontal slot branching off one of the vertical slots. Appliances, such as microwaves, often have 20-amp plugs and must be plugged into a 20-amp outlet. ... A 15-amp circuit is usually served by 14-gauge wire and is protected by a 15-amp circuit breaker or fuse.

The 20-watt amp is double the power of the 10-watt amp, but doubling the power only translates to an increase of 3 dB SPL. Remember, in order to sound "twice as loud," you need an increase of 10dB, so while a 20W amplifier will sound noticeably louder than a 10W amp, it will not sound twice as loud.

40 Watts / 24 Volts = 1.66 Amps. This 1.66 Amps is the amount of current that can safely be drawn on the 24volt R or C control circuit wire. Place an Ammeter on the R or C wire of a 40 VA transformer that has been replaced. Turn the Tstat to the “fan on” position • If the amperage is below the 1.66 try “cool and 60”.

40-amp 240-volt circuit: 40 amps x 240 volts = 9,600 watts. 50-amp 240-volt circuit: 50 amps x 240 volts = 12,000 watts.

In the below diagram you will notice that for a 220-volt outlet you would need a two-pole breaker. ... But for now, this pretty much covers a simple 15 or 20 amp 220 volts. The wiring needed for this type of insulation you would use 12/2 wire for a 20 amp installation.

So a 20 amp breaker usually has 12 gauge wire attached to it. If you replace it with a 30 amp breaker (which usually has thicker 10 gauge wire attached to it) then that could become very dangerous, if too much amperage flows through the wires, the wires could majorly overheat and cause a fire.

So say 120 Volts x 20 amps, is 2,400 Watts. Amperes are units of current. Volts are a measure of voltage.
