How do you measure load on a single pole circuit breaker?

Answer 1

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.

Answer 2

You can measure the load on a single pole circuit breaker by using a clamp meter to measure the current passing through the breaker. This will give you an indication of how much electrical load is being drawn by the devices connected to that breaker. Alternatively, you can also use a power meter to measure the power consumption of the devices on that circuit, giving you a more comprehensive view of the load.

Answer 3

Get a clamp meter and put it around the wires leading from the breaker.
