When measuring current on a meter, what relation should the meter capacity have to the expected amperage?

When measuring current with a meter, it is essential that the capacity of the meter is higher than the expected amperage. This is crucial for a couple of reasons. Firstly, if the meter's capacity is lower than the expected current, it could overload or damage the meter, leading to inaccurate readings or even permanent failure of the device. Additionally, using a meter with a higher capacity ensures that it can handle unexpected surges in current without risk of harm.

Moreover, having a higher capacity allows for a margin of safety, accommodating fluctuations in the current that may occur in the circuit being measured. This is particularly important in practical applications, where currents can vary due to different operating conditions or loads, ensuring that the readings remain reliable and safe throughout the measurement process.
