The safest andeasiest way is to get a good ammeter (make sure it is rated for the correct application with at least a CAT IV rating) and then take the hot wire and only the hot wire and put it into the clamp of the ammeter while the wire is under load. Then all you have to do is read the meter.
Note: when using an ammeter you can only test one side of the circuit at once either the hot side or the neutral side not both at once. If you try to put both wires under the clamps at the same time your readings will be wrong. The same goes for a 240v circuit you are only able to read one line at a time.

What is the capacity in amperes 20 amp circuit breaker supplying a continuous load?
For a continuous load the circuit breaker is set 25% higher than the load current. So a 20-amp breaker is used with a continuous 16-amp load.
Can you have two circuits off one breaker?
No, a breaker is designed to handle the load of only one circuit. Connecting two circuits to one breaker can overload the circuit and potentially lead to electrical hazards such as overheating, tripping the breaker, or causing a fire. Each circuit must have its own dedicated breaker.
Why would a circuit breaker switch spark?
the circuit breaker spark when it comes an over load, loss contact,but the probable cause is loss contact...and also the circuit breaker is going to be damage or destroyed.
Can you use a 2 pole breaker for a 120 volt single phase circuit?
A single phase circuit uses a 2 pole breaker if the circuit is 120/240 split phase and the load is connected 240. Both legs are hot, so both need to be protected. This is the normal US/Canada configuration.
Can you use two 15 amp single pole breakers in place of a double pole 30 amp breaker?
Yes. An everyday occurrence of this circuitry is in your kitchen counter split receptacles. The top half of the receptacle is a 15 amp circuit and from the same breaker the bottom half of the receptacle is another 15 amp circuit. A two pole single handle breaker is a common trip. If one of the circuits fed from the breaker faults the other connected circuit will shut off also. If you are talking about slot position in a breaker panel, you can remove the two pole breaker and install two single pole breakers.
A fuse or circuit breaker used in a circuit is usually inserted in?
A fuse or circuit breaker used in a circuit is usually inserted in series with the load.
A 32A breaker was controlling a lighting circuit but is now on a 6A breaker which is now buzzing what should you do?
Answer for countries in Europe and other world areas running a 50 Hz supply service.Depending on the load of your lighting circuit. I would measure the current with an inductive amp meter. once you know the current required for your lighting circuit, you then install a circuit breaker which is 15% higher than your load. eg, load is 10A. 10A load + 15 % = 12A breaker (15 A is ok as the breaker is used to protect the wiring and should be rated in consequence of your wiring by 25% less or its current rating, or less, not the load)The humming of your lighting circuit breaker indicates that your breaker is either faulty, or having a difficult time keeping a closed circuit. Or simply that the manufacturer produced a breaker that hums by nature of its construction.

What type of circuit breaker is required for a 240 v branch circuit?
the circuit breaker used will be miniature circuit breaker(MCB) maily used in homes.Answer for USA, Canada and countries running a 60 Hertz supply service.A two pole circuit breaker is used for a load of 240 volts. It is sized, according to the load amps of the device, to protect the wires that supply the load current.
Where is the double-pole circuit breaker located?
before the load
Why does an electrical breaker trip when you use a lot of appliances in the house?
since circuit breaker consists of coils they get heated up when high current flows, when this happens the coil get energised and pull the moving contacts to open thus the circuit breaker opens when high current flows.
Why would a circuit breaker switch spark?
the circuit breaker spark when it comes an over load, loss contact,but the probable cause is loss contact...and also the circuit breaker is going to be damage or destroyed.
What size fuse required to supply a continuous load of 32 amps?
80% of 40 = 32 amps Load the circuit breaker to 80% choose a conductor to suit the circuit Breaker min.

What circuit breaker rating do you need for a 3 phase electric motor?
The circuit breaker is sized to the full load amps of the motor times 250%.
How do you choose circuit breaker all the control circuit if i have 50kw power of motor?
The breaker should be sized to 250% of the motor's full load amperage.
