Question

Which two different ways can the current sensing circuit of a magnetic overload device be set up?

Answer 1

The current sensing circuit of a magnetic overload device can be set up using a resistor and a galvanometer, or using a circuit breaker or a ground fault circuit interrupter (GFCI).

Step-by-step explanation:

The current sensing circuit of a magnetic overload device can be set up in two different ways:

1. Using a combination of a resistor and a galvanometer, which gives an analog reading of current. This setup can be used to measure the current flowing through the circuit.
2. Using a circuit breaker or a ground fault circuit interrupter (GFCI), which are devices that open the circuit to protect it from overload or faults. These devices are designed to react quickly to changes in current and magnetic fields.

Both setups have their own advantages and are commonly used in different applications.
