Breakers and other electrical equipment are rated in voltage so you know what voltage they can withstand. The breaker could fail and start a fire if you apply a higher voltage than it is rated for. Breakers are actually rated in amps (current in excess of this will trip it), interrupting rating (how many amps the breaker can handle during a short circuit) and in volts (is the difference of potential or the pressure that is pushing the current). The breaker I am looking at is rated for 15 amps, 10,000 amps interrupting rating and 120/240 volts.

How do you measure the voltage by looking at a breaker box in a home?
You don't. You need test equipment to measure voltage.
What size breaker do you need for 3kva?
To calculate an answer a voltage must be stated.
Why would power be received before breaker but with breaker on no power is in any recepticles?
The voltage before the breaker is from the distribution panel's buss bars. This voltage is controlled by the panel's main breaker. To have no voltage on the terminal of the breaker means that either the breaker is shut off or it has gone into a trip position. If it has tripped push the handle of the breaker to the off position and then to the on position. This should reset the breaker. If the voltage is not present at the output terminal of the breaker after resetting it, then replace the breaker as it has a fault in it.
How do you test a 220 volt breaker?
You will need a multimeter to check a 220 volt breaker. You should unplug appliances that go to that particular breaker. Use the multimeter at the breaker to check the voltage. If it shows 220, then the breaker is okay. If it doesn't, then the breaker is no good.
Can breaker be bad and still show voltage?
A breaker that still shows full voltage after it has tripped is definitely bad.
What size of wire and breaker do you need for a 20kw electric furnace?
In order to properly size the wire per National Electric Code (NEC) standards you will need to know the amperage and the distance of the device (heater) from the source (circuit breaker panel). In order to know the amperage one would need to know the voltage since amperage changes inversely with voltage.
When a shunt trip breaker trips does the voltage remain on?
No, it does not have voltage in trip position.
High voltage will trip a circuit breaker?
A higher voltage means that a higher current will flow in the same load. It is the current that causes the breaker to trip.
Does the power supplied to trip shunt trip breaker have to be applied momentarily or can it latch?
A shunt-trip breaker trips when voltage is applied to the coil. It does not self-reset when the voltage is removed, the breaker must be reset manually. The trip voltage can either latch or be applied momentarily, but must be de-energized before the breaker will reset.
What is a Circuit breaker and explain type circuit breakers?
A circuit breaker is a switching device which can make,brake and carrying (or trip the circuit) that specified over currents for a small interval of time . There is a different types of Circuit Breaker's are there 1.According to their arc quenching media these are divided into 4 types a) Oil circuit breaker b) Air blast circuit breaker c) SF6 circuit breaker d) vacuum circuit breaker 2. According to their services the circuit breaker can be divided as a) Outdoor Circuit Breaker b) Indoor Breaker 3. According to the operating mechanism of circuit breaker they can be divided as a) Spring operated Circuit Breaker b) Pneumatic Circuit Breaker c) Hydrolic Circuit Breaker 4. According to the voltage level of installation these are divided into 3 types a) High Voltage Circuit Breaker b) Medium Voltage Circuit Breaker c) Low Voltage Circuit Breaker.
What is HT breaker?
high voltage breaking capacity
How many amps breaker you need for a 5000 watts immersion heater?
To answer this question the voltage of the immersion heater is needed. I = W/E.
