The only way is to use a meter, it does not have to be expensive. Radio Shack offers inexpensive meters. Simply "clamp" the meter around the circuit you want to test.

Good Luck.

Purpose of a breaker in an electrical circuit?

Breakers ensure that when too much amperage is being drawn through the circuit the power is shut off. Excessive amperage creates heat. Without a breaker that heat buildup could lead to fire.


When will a circuit breaker trip or turn off?

A circuit breaker has a specific amperage trip setting. That is the number on the handle of the breaker. When an amperage that is drawn by a load goes higher than the setting on the breaker, the breaker will trip off. This tripping action opens the circuit and drops off the load that was causing a higher than normal amperage.


What size breaker do you need for a well pump?

A breaker is based on the amperage that is drawn by the pump motor load. Find the full load amperage of the motor. The wire fed from the breaker has to be rated at 125% of the motors full load amperage. The breaker for motors have to be over sized, usually 250% of the motors full load amps.


Can 3 fans 115 volts be plug in one outlet on 120 volts?

Depends on the size breaker used in the distribution panel, and the total amperage drawn by any other devices being powered on that same circuit, and of course, the amount of amperage drawn by each of the 3 fans.


What is the function of a circuit breaker?

The purpose of a circuit breaker is to open the circuit in the event of an overload. Wires/conductors are only rated for a specific Amperage. If this amperage is exceeded the conductor/wire begins to heat up and given enough time it becomes a fire hazard. For instance a 15 amp breaker will trip once the Amps drawn through that circuit exceed 15 amps. The short answer is to keep you safe.

What amp breaker do you need for a 325 watt heater 120 VAC?

Electrical breakers are sized by the conductor that is connected to it. The conductor is sized by the current that is drawn by the circuit. The formula for amperage is I = W/E. Amps + Watts/Volts. 325/120 = 2.7 amps. A #14 copper conductor is rated at 15 amps. This is the minimum size wiring that is used for house circuits loads. The breaker for this size wiring will be a 15 amp breaker.


How many breaker amps can you use on a 70 amp panel?

The amperage that can be used from a service distribution panel is governed by the amperage of the main breaker. If the main breaker is 70 amps then up to a maximum of 70 amps can be taken from the panel before the main breaker trips on an over current fault. Any combination of branch circuits can come off of this panel as long as there is slots left for breakers to be installed. If you add up all of the breaker amperages in your distribution panel now you will see that the total is well above what your main breaker is rated for. The main breaker is used for two purposes, one to disconnect the panel from the utility supply source and two to limit the amperage that cam be drawn from the manufactures rated equipment. If the electrical panel's maximum rated current draw is 70 amps then that is what the manufacturer of the panel found, through UL testing, that that is all it can handle without becoming overheated due to the excessive current draw.


How many amps does a House draw?

Impossible to tell without a meter. Most homes are wired with a 60amp or 100amp (max) Panel. Checking how many amps are being drawn off a main hot wire should do the trick.Another perspective Actually... a house doesn't consume any electrical energy. The only way to use electrical energy is to turn on appliances or other electric devices. To determine the amperage consumption of your house, add the total amperage draw of all electrical devices that are on at any one time.


Can you use a 30 amp breaker for a stove?

The breaker commonly used for ranges is a 40 amp. This size is used to cover the total wattage of the range. If for some reason all of the top elements and the oven were in use at the same time then the amperage drawn would be just under the trip setting of the breaker. If this same scenario were played out on the range with a 30 amp breaker supplying the power it would trip the breaker.


How much amperage is drawn by a kiloWatt motor?

To answer this question the motor voltage is needed.


What is air circuit?

You may be referring to an air circuit breaker or, more accurately, and air-blast circuit breaker. This is a type of high-voltage circuit breaker in which the electrical arc, drawn when it opens, is stretched and snapped by a blast of air directed between the separating contacts -so the air is used as a method of extinguishing the arc. Often, these breaker's mechanisms are also driven by compressed air.
